ITAR, export controls and security clearances in space jobs, explained

Why so many rocket and satellite jobs say "U.S. person" or "U.S. citizen", what the export and clearance rules actually require, and which doors stay open whatever passport you hold.

On 29 October 2026, every one of the 2,847 job postings on SpaceX's public job board, from propulsion engineers to an accountant, ended with the same "ITAR requirements" paragraph: to conform to U.S. Government export regulations, the applicant must be a U.S. citizen or national, a lawful permanent resident, a refugee or an asylee, "or be eligible to obtain the required authorizations from the U.S. Department of State". On the same day all 551 Rocket Lab postings carried a similar clause ( Rocket Lab), as did all 186 at Astranis ( Astranis) and all 142 at Muon Space ( Muon Space), and each of 20 Blue Origin postings sampled that day said applicants must be a U.S. citizen or national, a green card holder, a refugee or an asylee. If you want to work in space in the United States, this paragraph is the first filter you meet, and it is the one most career advice explains worst.

The confusion comes from treating three separate gates as one. The first is the ordinary right to work in the United States. The second is export control: the International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR), which decide who may receive controlled technical information, and which define a "U.S. person" far more broadly than "citizen". The third is a security clearance, which decides who may be trusted with classified information, and which is in practice open only to citizens. A posting can invoke one, two or all three, and the rules, exceptions and realistic workarounds are different for each.

This guide works through each gate from the regulations up: what ITAR (22 CFR parts 120 to 130) and the EAR actually say, which space hardware sits under which, who counts as a U.S. person under the current section numbers, why hiring a foreign national can require a license, what employers' postings say today, how the Justice Department's case against SpaceX actually ended, how clearances are sponsored, investigated, timed and judged, how NASA badges its workforce, and what all of it means for dual citizens, international students and anyone looking at Europe. It is general information, not legal advice: the employer's export compliance or security office is the authority on any specific role.

1. Why space job postings ask for U.S. persons

The reason is physical before it is legal. A rocket that delivers a satellite to orbit and a missile that delivers a warhead across a continent share the same propulsion, guidance, structures and staging. The U.S. Munitions List says so directly: its first entry for launch vehicles covers "rockets, SLVs, and missiles capable of delivering at least a 500-kg payload to a range of at least 300 km", marked (MT) for the Missile Technology Control Regime ( 22 CFR 121.1, Category IV). Spacecraft raise the other half of the concern: the same list controls satellites that conduct signals intelligence, autonomously track moving objects in real time, broadcast positioning, navigation and timing signals, or inspect and service other spacecraft ( 22 CFR 121.1, Category XV). In space, the hardware is the military capability, which is why governments treat its know-how as something to be guarded.

The second fact explains why these rules reach hiring rather than just shipping. The government controls information as well as hardware, and information moves through people. Under ITAR, technical data is "released" by visual inspection of a defense article, by oral or written exchanges, or by handing someone the credentials to unencrypted files ( 22 CFR 120.56), and releasing it to a foreign person inside the United States is itself an export, which the regulation calls a deemed export ( 22 CFR 120.50). A foreign engineer looking at a turbopump drawing on a shared screen in California can therefore be an export to another country without anything crossing a border. Once that is true, every hiring decision in a rocket factory is also an export decision.

That is why it helps to separate the three gates before reading any posting. They come from different laws, are checked by different people, and exclude different groups.

The gates are independent. A green card holder passes the first two and not the third. An H-1B engineer passes the first, and the second only with a license. A citizen with unresolved debts passes the first two and may fail the third. The Justice Department's April 2023 employer fact sheet tells companies to "separate export compliance assessment from the Form I-9 process", because separating them "avoids a worker believing they are being asked to prove their citizenship or immigration status" just to be hired ( Hogan Lovells, quoting the DOJ fact sheet).

Many employers apply the export gate to the whole company, an accountant included, and that is a business choice rather than a legal requirement. Controlled drawings sit on shared drives, factory floors are full of hardware that reveals technical data to anyone who looks, licenses take time and can be refused, and a growing startup cannot cheaply wall off one part of its building. A blanket "U.S. persons only" rule removes the risk. What employers may not do is narrow it further: when the Justice Department settled with Honda Aircraft in 2019 over postings limited to citizens and green card holders, it noted that ITAR and the EAR do not authorize or require companies to hire only citizens and permanent residents, and the company paid a $44,626 civil penalty ( Holland & Hart via JD Supra).

In practice, the first thing to do with any space posting is to name which gate it invokes. "U.S. person" language is the export gate, and it includes refugees and asylees. "U.S. citizenship required" usually means the clearance gate, or a government contract that demands it. Silence means the role is probably open to anyone authorized to work, and the rest of this guide explains how to tell which situation you are in and what to do about it.

2. ITAR in plain language

ITAR is the set of regulations that implements section 38 of the Arms Export Control Act. The State Department's Directorate of Defense Trade Controls (DDTC) administers it to regulate the export, reexport, retransfer and temporary import of the defense articles and defense services listed on the U.S. Munitions List, while items outside that list, and outside other agencies' exclusive jurisdiction, fall under the EAR run by the Commerce Department's Bureau of Industry and Security ( State Department proposed rule, 1 Oct 2026). That division is the most important structural fact in space export control: every item is either on the Munitions List, and therefore ITAR, or almost always somewhere in the EAR.

ITAR's reach comes from a handful of definitions in 22 CFR part 120, and they are worth reading in the original because career advice tends to paraphrase them loosely. The four that matter most for a job seeker are these:

• Defense article: any item or technical data on the Munitions List, including models, mockups and anything that reveals technical data ( 22 CFR 120.31).
• Technical data: information "required for the design, development, production, manufacture, assembly, operation, repair, testing, maintenance, or modification" of defense articles, including blueprints, drawings, photographs and instructions ( 22 CFR 120.33).
• Defense service: furnishing assistance, including training, to foreign persons in the design, production, testing, operation or use of defense articles, in the United States or abroad ( 22 CFR 120.32).
• Export: a shipment out of the country, a release of technical data to a foreign person inside it, or performing a defense service for a foreign person ( 22 CFR 120.50).

Just as important is what the definitions leave out. Technical data does not include "general scientific, mathematical, or engineering principles commonly taught in schools, colleges, and universities", information in the public domain, or basic marketing information ( 22 CFR 120.33(b)), and the public domain includes material available in libraries, at open conferences and from fundamental research at accredited U.S. universities that is ordinarily published ( 22 CFR 120.34). Orbital mechanics from a textbook is not controlled; the qualification test data for a particular engine is. That line is why a foreign graduate student can study rocket propulsion and still be unable to see a company's engine drawings.

Licenses, penalties and the countries that cannot be licensed

When a release to a foreign person is needed, the usual vehicle is a license: a DSP-5 covers exports of unclassified technical data, and a license is required "for the oral, visual or documentary disclosure of technical data by U.S. persons to foreign persons" unless an exemption applies ( 22 CFR 125.2). Getting it wrong is expensive. The civil penalty for each violation can reach the greater of $1,271,078 or twice the value of the transaction ( 22 CFR 127.10), and willful violations are crimes punishable by up to $1,000,000 per violation and 20 years in prison ( 22 U.S.C. 2778(c)).

Some nationalities are close to unlicensable. The State Department maintains a policy of denying licenses for defense articles and services destined for Belarus, Burma, China, Cuba, Iran, North Korea and Venezuela, with Russia and several other countries subject to country-specific denial rules ( 22 CFR 126.1). For a candidate who holds citizenship of one of those countries, an employer's license application is unlikely to succeed, which is why some postings that say "U.S. person" are effectively closed to them while being open, in principle, to a German or Japanese engineer whose employer is willing to apply.

The 2022 renumbering, and where the rules are heading

If you read older guides, check the section numbers. In 2022 the State Department consolidated and restructured part 120, effective 6 September 2022, and the definition of "U.S. person" moved from section 120.15 to section 120.62, with "foreign person" moving from 120.16 to 120.63 ( 87 FR 16396). Section 120.15 now covers exemptions. A source that still cites 120.15 as the U.S. person definition predates the change.

The direction of travel since then is toward narrower controls. Executive Order 14268 of 9 April 2025, "Reforming Foreign Defense Sales to Improve Speed and Accountability", underpins recent ITAR rulemaking ( State Department final rule, 30 Dec 2025), and on 1 October 2026 the State Department proposed removing items that no longer provide "a critical military or intelligence advantage", with comments open until 30 November 2026 ( Federal Register). The category-specific changes in that proposal concern guns, aircraft, protective equipment and submersible vessels rather than the two space categories, and while its revisions to definitions such as "specially designed" would apply across the list, none of it is final, so the rules described in the next section remain the ones that govern space jobs today. For a job seeker the practical point is simple: the definitions above are stable, so learn them once, and treat any claim about what is "ITAR" as something to check against the Munitions List rather than accept.

3. The space categories of the U.S. Munitions List: IV and XV

Two of the Munitions List's 21 categories carry most of the space industry. Category IV covers "Launch Vehicles, Guided Missiles, Ballistic Missiles, Rockets, Torpedoes, Bombs, and Mines", and Category XV covers "Spacecraft and Related Articles" ( 22 CFR 121.1). Which one a job touches, and whether it touches either, decides how hard the export gate is.

Category IV is deliberately broad. Its paragraph (a) covers rockets, space launch vehicles and missiles above the 500 kg and 300 km threshold, below it, and, through paragraph (a)(5), any rocket or launch vehicle "not meeting the criteria" of the earlier paragraphs, so essentially every orbital and suborbital launcher is a defense article ( 22 CFR 121.1, Category IV). When the State Department rewrote the category during export control reform, a commenter asked whether any sounding or research rockets escaped it, and the Department answered that "all such rockets are controlled under USML Category IV" ( 79 FR 34, Jan 2014). The only carve-out a job seeker is likely to meet is for hobby rockets: model and high-power rockets made of paper, wood, fiberglass or plastic, without active controls, are excluded ( Category IV, Note 3 to paragraph (a)).

Category XV is narrower, and that narrowness is the whole story of the commercial satellite industry. Paragraph (a) lists the spacecraft that remain defense articles "whether designated developmental, experimental, research, or scientific, or having a commercial, civil, or military end-use" ( 22 CFR 121.1, Category XV). Among them are spacecraft that:

• Detect nuclear detonations or are designed to mitigate their effects;
• Conduct SIGINT or MASINT, or autonomously track moving objects in real time;
• Carry high-end imagers, such as visible or infrared optics with a clear aperture above 0.50 m, or certain radars;
• Broadcast navigation signals (positioning, navigation and timing), or perform autonomous collision avoidance;
• Inspect, grapple or dock with other spacecraft, unless they dock only through the NASA Docking System.

Everything not on that list "is subject to the EAR" under ECCNs 9A004 and 9A515, and the list explicitly leaves the International Space Station and its parts under the EAR as well ( Category XV notes). A communications satellite bus with an ordinary payload is therefore usually an EAR item, while a spy satellite, a GPS satellite or a missile-warning satellite is ITAR. The same company can build both, which is why a single employer's postings can have different export clauses for different programs.

Launch integration is ITAR even when the satellite is not

One provision catches people by surprise. Category XV(f) defines the related defense services to include helping a foreign person integrate "a satellite or spacecraft to a launch vehicle, including both planning and onsite support, regardless of the jurisdiction, ownership, or origin of the satellite or spacecraft, or whether technical data is used", and the same for launch failure analysis ( 22 CFR 121.1, Category XV(f)). A mission integration engineer at a launch company working with a foreign customer's satellite is performing a controlled defense service even if the satellite itself is an ordinary EAR item, so those roles sit firmly on the ITAR side.

A revision is pending but not final. On 23 October 2024 the State Department proposed rewriting Categories IV and XV to clarify the text, add and remove items, and create three new license exemptions ( 89 FR 84482); a search of the Federal Register in late October 2026 shows no final rule. To apply this to your own search, map the job to the hardware: propulsion, avionics or guidance on any launcher points to Category IV; a payload that does intelligence, navigation or high-resolution imaging points to Category XV; a commercial communications or Earth-observation bus with ordinary performance points to the EAR, which the next section explains.

4. What moved to the EAR: export control reform, 9x515 and the 600 series

For fifteen years, every satellite was a weapon in law. The Strom Thurmond National Defense Authorization Act for Fiscal Year 1999 required that "space-related items, including all satellites" be controlled as defense articles and removed the President's authority to move them off the Munitions List ( State Department rule, 13 May 2014). Defense and State reviewed the risks of changing that under the 2010 defense authorization act, Congress returned the authority to the President in section 1261 of the 2013 act, and the State Department then rewrote Category XV so that "certain commercial communications and remote sensing satellites" became subject to the EAR, effective 10 November 2014 (same source). Radiation-hardened microelectronics moved earlier, to new ECCN 9A515.d, effective 27 June 2014.

The result is the EAR structure space engineers now work inside. The Commerce Control List groups items into categories, and Category 9 holds aerospace. ECCN 9A515 covers "spacecraft" and related commodities, and ECCN 9E515 covers the technology "required" for their development, production, operation, installation or repair ( 15 CFR part 774, Supplement No. 1). The "515" entries were created in the 2014 reform to receive the spacecraft items moved off the Munitions List ( State Department rule, 13 May 2014). Alongside them sit the 600 series, the "604", "610" and similar entries that received other transferred items, as when the 2014 rewrite of Category IV moved military explosive excavating devices to ECCN 0A604.b ( 79 FR 34). For space, that family includes ECCN 9A604, "Commodities related to launch vehicles, missiles, and rockets", and 9E604 for the matching technology ( 15 CFR part 774, Supplement No. 1). In shorthand, "9x515" means the family of 9A515, 9B515, 9D515 and 9E515, and "9x604" the same for launch-vehicle-related items.

Moving to the EAR did not mean decontrol. The 9E515 technology entry is controlled for national security, missile technology, regional stability and anti-terrorism reasons, and its regional stability control is "RS Column 1" ( 15 CFR part 774, Supplement No. 1), which requires a license for exports to all destinations except Australia, Canada and the United Kingdom ( 15 CFR 742.6). In 2024 the Commerce Department loosened parts of this: one rule reduced license requirements on less sensitive spacecraft items "to reflect the close relations with certain countries" ( 89 FR 84770), and another removed license requirements for certain remote sensing and in-space servicing spacecraft for Australia, Canada and the United Kingdom ( 89 FR 84766).

Why an EAR role is still easier than an ITAR role

The EAR has its own deemed export rule: releasing "technology" or source code to a foreign person in the United States is an export ( 15 CFR 734.13), which the Commerce Department summarizes as "the sharing or release of controlled technology or source code to a foreign person within the United States" ( BIS, deemed exports). Its definition of foreign person mirrors ITAR's, excluding citizens, permanent residents and other protected individuals ( 15 CFR 772.1). Two differences make EAR roles more open in practice, and they are summarized below.

The first difference is how nationality is counted: ITAR counts every citizenship a person "has held or holds", while the EAR counts only the most recent. The second is that EAR controls vary by destination and have exceptions, so the analysis for a given engineer may end in "no license needed" or in a license that is routinely granted. If you are not a U.S. person, roles built around EAR-controlled commercial spacecraft, ground software or data products are therefore the part of the industry where your nationality is most likely to be workable, which is why the rest of this guide keeps returning to the question of which side of the line a job sits on.

5. Who counts as a U.S. person

The current ITAR definition is short. "U.S. person means a person who is a lawful permanent resident as defined by 8 U.S.C. 1101(a)(20) or who is a protected individual as defined by 8 U.S.C. 1324b(a)(3)"; it also covers U.S.-incorporated businesses and federal, state and local government entities, and "does not include any foreign person" ( 22 CFR 120.62). A foreign person is the mirror image: any natural person who is not a lawful permanent resident or protected individual, plus foreign companies, governments and international organizations ( 22 CFR 120.63).

The definition borrows its list from immigration law. A protected individual is a citizen or national of the United States, a lawful permanent resident, a person granted temporary residence under two 1986 amnesty provisions, a person "admitted as a refugee under section 1157", or a person "granted asylum under section 1158" ( 8 U.S.C. 1324b(a)(3)). Read literally, that gives the U.S. person population for space jobs: citizens, nationals, green card holders, refugees and asylees. Everyone else who is lawfully working in the country, whether on an H-1B, an L-1, an O-1, Optional Practical Training, Temporary Protected Status or a work permit tied to a pending application, is a foreign person for export purposes.

The clearance column comes from different rules, explained in section 9: an executive order allows non-citizens only "limited access" for specific programs ( Executive Order 12968, section 2.6), and the industrial security rule says such a Limited Access Authorization is not valid for Top Secret, intelligence or communications security information ( 32 CFR 117.10(k)). The distinction between "asylee" and "asylum applicant" is the one most often misunderstood: the statute covers a person who "is granted asylum", so the protection begins with the grant, not the application.

One subtlety cuts in the green card holder's favor. The immigration statute strips "protected individual" status, for anti-discrimination purposes, from a permanent resident who does not apply for naturalization within six months of becoming eligible, or who has not naturalized within two years of applying unless actively pursuing it ( 8 U.S.C. 1324b(a)(3)). ITAR, however, names lawful permanent residents separately, by reference to 8 U.S.C. 1101(a)(20) ( 22 CFR 120.62), so a long-term green card holder who never naturalizes remains a U.S. person for export purposes even where that discrimination protection has lapsed.

To use this, know your status precisely and keep the document that proves it. An employer doing an export check may ask for proof of U.S. person status for roles that genuinely need it, but the Justice Department's guidance tells employers to run that check only for positions that require it, to say why they are asking, and not to dictate which documents you present for the Form I-9 ( Hogan Lovells summary of DOJ guidance). If a recruiter asks for a passport "for ITAR" before an offer, for a role that does not touch controlled data, that is worth a polite question.

6. Deemed exports: why hiring a foreign national can need a license

The deemed export rule is what turns a hiring decision into a licensing decision. Under ITAR, releasing technical data to a foreign person in the United States is an export, and "is deemed to be an export to all countries in which the foreign person has held or holds citizenship or holds permanent residency" ( 22 CFR 120.50). Under the EAR, the release of controlled technology is a deemed export to the person's most recent country of citizenship or permanent residency ( 15 CFR 734.13). Either way, the employer must hold an authorization before the new hire sees the controlled material, not after.

Immigration paperwork builds this in. Every company petitioning for an H-1B, H-1B1, L-1 or O-1A worker must certify on Form I-129 that it has reviewed the EAR and ITAR and determined whether a license is needed to release controlled technology to the worker, and if one is needed, that it "will not release or otherwise provide access" until the authorization arrives ( USCIS Form I-129 instructions). The same instructions note that the requirement "will affect only a small percentage of petitioners because most types of technology are not controlled", which is true of the economy as a whole and much less true of a rocket company.

From the employer's side, the decision is an expected-value calculation. A license costs compliance staff time, has to be in hand before the person starts the controlled work, may come with conditions that wall the person off from parts of the work, and may be refused outright for nationals of countries under the State Department's denial policy ( 22 CFR 126.1). Against that sits the value of the candidate. For a rare specialist, the license is worth it; for a role with many qualified U.S. person applicants, most employers will not file. The postings say this openly: Muon Space states that it "may, for legitimate business reasons, decline to pursue any export licensing process" ( Muon Space posting), and Planet makes employment in export-controlled roles contingent on access "without additional export licensing being required" by either agency ( Planet posting).

Three ways the rule bends

The rule has edges that matter for real careers. The first is the university: research whose results are "ordinarily published and shared broadly in the scientific community" is fundamental research and falls in the public domain, unless the university accepts restrictions on publication or specific access controls ( 22 CFR 120.34). This is why international graduate students can work in university space labs on open projects, and why the same student may be excluded from a sponsored project with publication restrictions.

The second edge is abroad. ITAR has an exemption that lets an authorized foreign end user transfer unclassified defense articles to its own dual-national or third-country-national employees within the country where it is located, provided it has safeguards against diversion, such as host-nation security clearances or employee screening backed by non-disclosure agreements ( 22 CFR 126.18). The third is the license itself: Planet's German subsidiary states that it "is authorized to receive U.S. export-controlled information" under a license from the Commerce Department ( Planet Labs Germany posting), which shows the route a company can take when it wants foreign staff on controlled work.

How to apply this: if you are a foreign person, ask early, and ask specifically. Does the role involve controlled technical data, under ITAR or the EAR? Has the company obtained deemed export licenses for comparable hires? Is your nationality one the company can realistically license? A recruiter who can answer those three questions has an export compliance team behind them; one who cannot is probably applying a blanket rule.

7. How employers actually handle it

Reading postings side by side shows that "ITAR" means different things at different companies. Some list exactly the U.S. person categories and leave the license door open in writing; some close it; some go further and require citizenship for every cleared role. The table summarizes what seven employers' postings said on 29 October 2026.

Two patterns stand out. First, at launch and spacecraft companies the export clause is universal: every SpaceX, Rocket Lab, Astranis and Muon Space posting carried one, accounting roles included, which is the blanket approach described in section 1. Planet, a satellite operator that sells imagery and data, is different: 66 of its 130 postings carried the export block that day, and the rest, mostly software, data, sales and product roles in the United States and Europe, did not ( Planet job board). The more of a company's value sits in data and software rather than hardware, the more of its roles tend to sit outside the export gate.

Second, citizenship requirements and U.S. person requirements are not the same thing, and the law treats them differently. The immigration statute bars discrimination based on citizenship status against protected individuals, but exempts discrimination "required in order to comply with law, regulation, or executive order, or required by Federal, State, or local government contract" ( 8 U.S.C. 1324b(a)(2)(C)). A cleared role or a contract that specifies citizens can therefore lawfully say "U.S. citizen". An export-controlled role generally cannot exclude refugees, asylees or green card holders, because the export rules treat them exactly like citizens. The statute does allow an employer to prefer a citizen over an equally qualified non-citizen ( 8 U.S.C. 1324b(a)(4)), which is a tiebreaker, not a license to exclude.

The practical reading is short. If a posting lists citizens, green card holders, refugees and asylees, it is applying the export gate correctly and you qualify if you hold any of those statuses. If it adds "or eligible to obtain authorization", a foreign person can apply and should raise the license question in the first conversation. If it says "U.S. citizenship required", look for the clearance or contract behind it; if there is none and the role is not cleared, the requirement may be broader than the law allows.

8. The Justice Department's case against SpaceX

The case that made this debate public was brought under the immigration statute's anti-discrimination provision, not under export law. The Justice Department filed its complaint with the Office of the Chief Administrative Hearing Officer (OCAHO), the administrative court for these claims, as case No. 2023B00082 on 23 August 2023 ( court filing, S.D. Tex.). It alleged that from September 2018 to May 2022 SpaceX discouraged asylees and refugees from applying, rejected or refused to consider them, and claimed it could hire only citizens and permanent residents because of export control laws; according to the department, of about 10,000 hires in that period only one was an asylee and none were refugees ( NPR).

The government's legal position was a reading of the export rules themselves. "Asylees' and refugees' permission to live and work in the United States does not expire, and they stand on equal footing with U.S. citizens and lawful permanent residents under export control laws," the department said ( NPR), and it argued that "no law, regulation, executive order or government contract required or permitted SpaceX to engage in the widespread discrimination" its investigation found ( FOX 7 Austin). Elon Musk called the suit "yet another case of weaponization of the DOJ for political purposes" and said the company had been told that hiring anyone who was not a permanent resident "would violate international arms trafficking law" ( NPR).

SpaceX denied wrongdoing, saying in a November 2023 filing that export laws impose "strict limitations on who it can employ" ( FOX 7 Austin). The case never reached a ruling on any of these arguments. SpaceX also sued in federal court in Texas, arguing that the administrative law judge system hearing the case was unconstitutional ( Immigration Policy Tracking Project), and the sequence after that is set out below.

A dismissal with prejudice means the case cannot be brought again ( FOX 7 Austin). The accurate summary is therefore that the government dropped the case for good in February 2025, and that no court or administrative judge ever decided whether SpaceX discriminated or whether its constitutional challenge was right.

What the case did not change is the regulation. Refugees and asylees are U.S. persons because 22 CFR 120.62 defines them that way through 8 U.S.C. 1324b(a)(3) ( 22 CFR 120.62), and that has nothing to do with how one lawsuit ended. SpaceX's own postings now spell it out, naming "Refugee under 8 U.S.C. § 1157" and "Asylee under 8 U.S.C. § 1158" in the same list as citizens and green card holders ( SpaceX posting). If you are a refugee or asylee and are told a space role is closed to you "because of ITAR", the regulation is on your side; say so, and if the employer persists, the anti-discrimination provision of 8 U.S.C. 1324b is the law that covers it.

9. Security clearances: who needs one and what the levels mean

A clearance answers a different question from export control. Export control asks where information may go; a clearance asks whether a specific person can be trusted with information whose disclosure would harm national security. The executive order on classification defines three levels by the damage an unauthorized disclosure "reasonably could be expected to cause": Confidential for damage, Secret for serious damage, and Top Secret for exceptionally grave damage ( Executive Order 13526, section 1.2). No other terms may be used to label U.S. classified information (same source).

On top of the three levels sit additional accesses. The government's own explainer lists Sensitive Compartmented Information (SCI), Special Access Programs (SAPs) and the "Q" and "L" accesses for nuclear weapons information as supplements to a clearance rather than separate levels ( Personnel Vetting Basics fact sheet). Being "eligible" is also not the same as having "access": eligibility comes from the investigation, while access to any particular information also needs a need-to-know and a signed non-disclosure agreement ( 32 CFR 117.10(a)), and the government deliberately keeps some vetted people eligible but without access until their work requires it ( Personnel Vetting Basics).

Who in the space industry needs one

Clearances follow classified contracts, and in space those come from national security space: the military space mission, the intelligence agencies that operate satellites, and the contractors who build for them. The National Reconnaissance Office is one of the intelligence community agencies overseen by the Department of Defense, which recent federal reports call the Department of War ( PAC legacy metrics, FY2026 Q3). On the contractor side, cleared roles show up even at commercial companies: SpaceX had about 190 postings mentioning a Secret or Top Secret clearance on 29 October 2026, including Starshield roles requiring an "Active Top Secret, Top Secret SCI, or DOE Level Q clearance" ( SpaceX posting), and Astranis's national security sales director role asks for TS/SCI eligibility and willingness to sit a counterintelligence polygraph ( Astranis posting).

Most space jobs, by contrast, need no clearance at all. Commercial launch, commercial communications, Earth observation and NASA science missions run largely on unclassified work, and NASA's own badging rules rest on suitability and credentialing investigations, covered in section 14, rather than clearances. When a posting says "ability to obtain a clearance", the employer will sponsor you after hiring; when it says "active clearance", it wants someone already cleared, usually because the program cannot wait for an investigation.

Citizenship is the hard line. The executive order on access lets agencies grant non-citizens with special expertise only "limited access" to classified information for specific programs, never beyond what is releasable to their country of citizenship, and only if the prior 10 years of their life can be investigated ( Executive Order 12968, section 2.6). For contractors, the industrial security rule tells companies to "make every effort to ensure that non-U.S. citizens are not employed in duties that may require access to classified information" and makes the resulting Limited Access Authorization unavailable for Top Secret, intelligence, communications security and several other categories ( 32 CFR 117.10(k)). Military service is not a shortcut around this: green card holders can enlist in the armed forces ( 10 U.S.C. 504), but a regular clearance still turns on citizenship under the same executive order. If a cleared career is your goal and you are not yet a citizen, naturalization is the step that matters, and the pay difference it unlocks is covered in the space industry salaries guide.

10. How a clearance is granted: sponsorship, the SF-86 and the investigation

You cannot apply for a security clearance yourself. The industrial security rule says contractors may request eligibility only for their own employees or consultants, only when access is "essential in the performance of tasks or services related to the fulfillment of a classified contract", and never "to establish a cache of cleared employees" ( 32 CFR 117.10). The government's explainer describes the sequence from the candidate's side: once an agency or contractor extends a conditional or tentative offer, you are asked for fingerprints and an electronic questionnaire covering places lived, employment, foreign travel and close associates ( Personnel Vetting Basics).

That questionnaire is the SF-86, the Questionnaire for National Security Positions, revised in November 2016, whose printable version runs to more than 130 pages ( OPM, SF-86). You complete it online in eApp, the National Background Investigation Services application developed by the Defense Counterintelligence and Security Agency (DCSA), which "has replaced" the older e-QIP system ( NIH Office of Research Services). Many questions look back seven years, and the form ends with a certification that "a knowing and willful false statement on this form can be punished by fine or imprisonment or both (18 U.S.C. 1001)" ( SF-86).

The process that follows is easier to understand as a pipeline than as a list of agencies.

From a conditional job offer to continuous vetting

Investigation tiers

The depth of the investigation depends on how the position is designated, not on how senior you are. Under the legacy model, positions with Secret, Confidential or "L" access get a Tier 3 investigation and positions with Top Secret, SCI, "Q" access and most special access programs get a Tier 5; the reformed model collapses five tiers into three, Low, Moderate and High, and the transition "will take several years to complete" ( Personnel Vetting Basics). The rollout is under way: in April 2026 the FBI became the first investigative provider approved to run investigations under the new standards, and all providers are due to offer them by the end of fiscal year 2027 ( PAC quarterly progress report, FY2026 Q3).

Investigators then verify what you wrote, may interview you and people who know you, and consolidate everything in a report of investigation, which an adjudicator outside the investigation reviews to make the trust determination ( Personnel Vetting Basics). To prepare, assemble the raw material before anyone asks: every address and employer with dates and a reference for at least the last seven years, foreign travel, foreign contacts, debts and any police or drug history. Most delays and most avoidable denials begin with an incomplete or inaccurate form, and the adjudicative rules treat deliberate omissions more harshly than the underlying facts, as section 13 shows.

11. How long a clearance takes, and what interim access means

The government publishes its clearance timeliness every quarter through the Security, Suitability, and Credentialing Performance Accountability Council (PAC). Its headline end-to-end figure runs "from the time of agency initiation of information collection from an applicant to the date adjudication is reported in a repository" ( PAC legacy metrics, FY2026 Q3), and it has traditionally been reported as the average of the fastest 90 percent of cases. Moderate Risk cases include Secret clearances and High Risk cases include Top Secret (same source).

The trend is better, and still far from target. The fastest-90-percent end-to-end time for High Risk cases fell from 220 days in the last quarter of fiscal 2025 to a projected 146 days in the quarter to June 2026, and Moderate Risk from 109 to a projected 82, performance the council itself says "remains much too high" compared with its targets of 75 days for High Risk and 40 days for Moderate Risk ( PAC quarterly progress report, FY2026 Q3). Remember that these are averages for the faster nine-tenths of cases: if your file has complications, such as years abroad, foreign family or financial issues, expect to be in the slower tail that the average excludes.

The investigation phase, measured two ways

The investigation is the longest single phase, and from the third quarter of fiscal 2026 the council began reporting it on 100 percent of cases instead of the fastest 90 percent, a change it says "leads to slower reported speeds but more accurately captures reality" ( PAC quarterly progress report, FY2026 Q3). Its table for DCSA, the largest investigator, reads as follows.

Source: PAC quarterly progress report, FY2026 Q3. A warning sits behind these numbers: DCSA's pending inventory climbed from a low of about 98,000 cases in January 2026 to more than 152,000 in the third quarter, driven by follow-up on continuous vetting alerts and a surge of military and agency requests, and the council warns that the increase "risks slowing background investigation timeliness in coming quarters" ( PAC legacy metrics, FY2026 Q3; PAC quarterly progress report).

Starting work before the clearance is final

The end-to-end figure overstates how long most people wait to start. A preliminary determination is "a risk-based decision to allow an individual to begin work before the full personnel vetting process is complete", based on clean forms, fingerprints and high-yield checks, and roughly 80 percent of workers being vetted do not have to wait for a final determination to onboard ( PAC legacy metrics, FY2026 Q3). Those decisions come in weeks, not months.

The data has limits the council states openly: preliminary determinations are not yet in a central repository, and only about half of agencies responded in the latest collection ( PAC legacy metrics, FY2026 Q3). For contractors, the formal version is temporary eligibility, "previously called interim", which the government may grant for Top Secret, Secret or Confidential access only "if there is no evidence of adverse information" that calls eligibility into question ( 32 CFR 117.10(l)). In practice, a clean file can mean starting a cleared job within weeks while the full investigation runs, and a file with issues means waiting for the final answer.

If you already hold eligibility, moving is fast: DCSA reports deciding Transfer of Trust cases within the Department of War in up to 2 days ( PAC legacy metrics, FY2026 Q3). That asymmetry, months for a new clearance against days for an existing one, is the economic reason employers pay a premium for cleared candidates and post "active clearance required". The lesson for planning is to budget months for a first clearance, to ask whether the employer will start you on a preliminary determination, and to treat your first cleared job as an investment that every later employer can reuse.

12. Polygraphs, continuous vetting and Trusted Workforce 2.0

Some positions add enhanced vetting: medical, psychological or polygraph evaluations, which "often apply to jobs within the Intelligence Community or law enforcement agencies", and which make the average time to a decision "much longer" ( Personnel Vetting Basics). In space, the polygraph shows up on programs for national security customers, and postings name the type, usually either a counterintelligence polygraph or the broader full-scope polygraph. Astranis asks one national security sales candidate for willingness to submit to a counterintelligence polygraph ( Astranis posting), while a SpaceX special programs engineering role asks for "Active Top-Secret or Top-Secret SCI with a full scope polygraph" ( SpaceX posting).

The bigger change for anyone who already holds a clearance is Trusted Workforce 2.0, the reform the council launched in 2018 and which the current administration says it is "revitalizing" ( PAC quarterly progress report, FY2026 Q3). In June 2025 the council adopted four goals for it: getting people to work faster, eliminating waste, optimizing risk management, and strengthening the experience of the people being vetted (same source).

Its core mechanism is continuous vetting, which "replaced legacy periodic reinvestigations" using automated record checks, agency-specific information and time- and event-driven investigative steps ( PAC legacy metrics, FY2026 Q3). At the end of June 2026, DCSA retired its legacy periodic reinvestigation products and now, with limited exceptions, only enrolls people in continuous vetting ( PAC quarterly progress report, FY2026 Q3). The automated checks surface "actionable information that was not previously known" from self-reporting or third parties ( PAC legacy metrics), and alerts needing follow-up are a main reason DCSA's inventory rose in 2026 ( PAC legacy metrics).

The old rhythm of a clearance, investigated once and then reinvestigated at fixed intervals, is gone. A missed tax filing, a new arrest record or a large debt can now surface between investigations instead of waiting for the next one, and the system rewards people who report changes themselves before an alert does it for them. The adjudicative guidelines treat voluntary reporting, and truthful, complete answers, as factors in a current clearance holder's favor ( SEAD 4, paragraph 2(f)). If you hold a clearance, find out what your security office requires you to report, and report early.

13. The adjudicative guidelines and the issues that sink applications

Every executive branch agency judges clearance eligibility against one standard: Security Executive Agent Directive 4, the National Security Adjudicative Guidelines, effective 8 June 2017, which the industrial security rule incorporates for contractor employees ( SEAD 4; 32 CFR 117.10(a)(2)). The process is "an examination of a sufficient period and a careful weighing of a number of variables of an individual's life", known as the whole-person concept, and "any doubt concerning personnel being considered for national security eligibility will be resolved in favor of the national security" ( SEAD 4, paragraph 2).

The thirteen guidelines are lettered A to M, and it helps to see them grouped by the kind of question they ask ( SEAD 4).

Adjudicators weigh the nature and seriousness of conduct, its frequency and recency, the person's age at the time, rehabilitation, the potential for coercion and the likelihood of recurrence ( SEAD 4, paragraph 2(d)). That list is the honest answer to "will X disqualify me": almost nothing is automatic, and almost everything depends on when it happened, whether it is over and whether you told the truth about it.

Honesty, money and foreign contacts

The most avoidable failure is dishonesty on the form itself. SEAD 4 says "any incident of intentional material falsification or purposeful non-cooperation with security processing is of significant concern" ( SEAD 4, paragraph 2(i)), and it lists prompt, good-faith efforts to correct an omission "before being confronted with the facts" as a mitigating condition (same source, Guideline E). A disclosed problem is a fact to be weighed; a concealed one becomes a second, often worse, problem.

Money is the most common substantive issue. Guideline F treats "inability to satisfy debts", "unwillingness to satisfy debts regardless of the ability to do so", a history of unmet obligations, and failure to file or pay federal, state or local income taxes as potentially disqualifying, because "an individual who is financially overextended is at greater risk of having to engage in illegal or otherwise questionable acts to generate funds" ( SEAD 4, Guideline F). Foreign contacts are the second. For people with family abroad, Guideline B's mitigating conditions turn on whether the relationships put you in a position of having to choose between a foreign interest and the United States, whether your ties in the United States are deep and longstanding, and whether you have reported contacts as required (same source, Guideline B).

Marijuana and federal law in 2026

Drug use is where state law and federal law diverge, and the clearance system follows federal law. Guideline H covers the illegal use of any "controlled substance" as defined in federal law, and lists testing positive, illegal possession, use while holding a clearance and "failure to clearly and convincingly commit to discontinue" use as potentially disqualifying ( SEAD 4, Guideline H). The SF-86 asks about illegal drug use in the last seven years "in accordance with Federal laws, even though permissible under state laws" ( SF-86, Section 23). In December 2021 the Director of National Intelligence wrote that prior recreational marijuana use "may be relevant to adjudications, but not determinative" ( Government Executive).

Federal scheduling moved in 2026, but only partly. A final rule effective 28 April 2026 placed FDA-approved drug products containing marijuana, and marijuana subject to a state medical marijuana license, in Schedule III ( Federal Register), and the Drug Enforcement Administration set a hearing beginning 29 June 2026 on rescheduling marijuana more broadly ( Federal Register); a search of the Federal Register in late October 2026 shows no final rule on that broader question. Schedule III substances are still controlled substances under the guideline's definition, and government contracts lawyers at Arnold & Porter concluded after the April rule that, absent future changes to the adjudicative guidelines, clearance applicants and holders remain prohibited from using medical marijuana even where state law permits it ( Arnold & Porter).

The practical advice that follows is the same as before the rule: stop any marijuana use well before you sign an SF-86, disclose past use truthfully, and do not use it while holding a clearance. One reassurance is worth knowing in the same breath: under Guideline I, "no negative inference concerning the standards in this guideline may be raised solely on the basis of mental health counseling" ( SEAD 4, Guideline I), so seeking help is not a reason to fear the process.

14. NASA badging and federal employment

NASA civil service jobs and NASA contractor jobs live under different rules, and the difference matters for non-citizens. For civil service, the Office of Personnel Management states that "under Executive Order 11935, only United States citizens and nationals may be appointed to competitive service Federal jobs", with rare exceptions when no qualified citizen is available, and that Congress often restricts non-citizen hiring in the excepted service through appropriations provisions too ( OPM). Becoming a NASA civil servant is therefore, in practice, a citizens' route.

Everyone who works at a NASA center, civil servant or contractor, needs a badge, and NASA's badging directive applies to "all NASA civil service employees and contractor employees" alike ( NPR 1600.4B, Chapter 2). The current version, NPR 1600.4B, took effect on 3 August 2025 (same source). It requires at least a Tier 1 investigation for anyone needing routine, unescorted physical or logical access to NASA assets for more than 179 days in a 365-day period, and at least a national criminal history check (NCHC) for shorter periods ( NPR 1600.4B, Chapter 3). That investigation supports a Personal Identity Verification (PIV) card, the federal credential that verifies identity under HSPD-12 and is distinct from a clearance ( Personnel Vetting Basics).

Foreign nationals at NASA

Foreign nationals can work at NASA centers, usually through contractors, universities or international partners, but the directive adds conditions. A foreign national needs three years of residence in the United States before NASA will run the background investigation behind a PIV card; until then, centers rely on database checks, including the NCHC, the SAVE immigration status check and a restricted-party screen (Visual Compliance), before issuing an Agency Smart Badge or a center-specific badge instead ( NPR 1600.4B, Chapter 4). Access is "determined on a case-by-case basis" and reviewed against export control and other policies, and "NASA resources shall be given to U.S. citizens prior to consideration of foreign nationals" (same source).

Escort rules depend on nationality. Foreign nationals from designated countries "shall be escorted at all times", normally one escort per visitor, unless they have completed a Tier 1 or higher investigation and the center chief of protective services exempts them; those from other countries with a completed criminal history check may be unescorted at the center's discretion ( NPR 1600.4B, Chapter 4). For a technician or engineer heading to a center through a contractor, the practical sequence is the contractor's own export screening, then NASA's identity process, then the badge, and the aerospace technician guide covers how contractor hiring at centers works. If you are not a citizen and want NASA work, contractor and university routes are open where civil service is not, but plan for the residency clock and the escort rules.

15. Dual citizens

Dual citizenship is simpler than people fear on the export side and more nuanced on the clearance side. For export control, a U.S. citizen is a protected individual and therefore a U.S. person, whatever other passports they hold ( 22 CFR 120.62; 8 U.S.C. 1324b(a)(3)). An American who is also French, Indian or Chinese needs no license to see ITAR technical data. The nationality analysis applies only to foreign persons.

For a foreign person with two or more foreign nationalities, the two regimes diverge sharply. ITAR deems a release to go to "all countries in which the foreign person has held or holds citizenship" ( 22 CFR 120.50(b)), so a British and Iranian dual national is assessed as Iranian too, and Iran is on the State Department's denial list ( 22 CFR 126.1). The EAR looks only at the most recent country of citizenship or permanent residency ( 15 CFR 734.13(b)). For dual nationals working for foreign companies abroad, ITAR's section 126.18 exemption offers a separate route, conditioned on the employer's safeguards against diversion, such as screening employees for contacts with denial-policy countries ( 22 CFR 126.18).

On the clearance side, SEAD 4 is explicit that "by itself, the fact that a U.S. citizen is also a citizen of another country is not disqualifying without an objective showing of such conflict or attempt at concealment" ( SEAD 4, Guideline C). What can raise concern is behavior:

• Not reporting a foreign passport or identity card when required;
• Not using a U.S. passport to enter or leave the United States;
• Foreign government service, or acting for a foreign interest against U.S. security interests;
• Using foreign citizenship to protect financial or business interests in violation of U.S. law;
• Acquiring a new citizenship, or acts of expatriation.

The mitigating conditions in the same guideline include citizenship "based solely on parental citizenship or birth in a foreign country" with no evidence of foreign preference, and a willingness to renounce a citizenship that conflicts with U.S. interests ( SEAD 4, Guideline C). Family abroad is assessed separately under Guideline B (foreign influence), so a dual citizen with close relatives in the other country should expect questions under both. In practice: declare the second passport, travel on your U.S. passport in and out of the country, keep a record of foreign contacts, and expect a longer investigation if the other country is one the United States treats as an adversary.

16. International students and visa holders: realistic paths

If you are in the United States on a student or work visa, the honest starting point is that ITAR roles at launch companies, cleared roles and NASA civil service are, for now, mostly closed, and that a large part of the space economy is not. The work is to find that part deliberately rather than applying everywhere and being filtered out at the export clause. The paths below are ordered roughly from most to least common.

The first path is the work-authorization route most international graduates use. Students with STEM degrees can apply for a 24-month extension of post-completion Optional Practical Training, but only with an employer enrolled in E-Verify ( USCIS, STEM OPT). An H-1B petition then requires the employer's export certification described in section 6 ( USCIS Form I-129 instructions). The $100,000 payment imposed in September 2025 on certain H-1B petitions for people outside the United States was blocked by court order as of 7 October 2026, with the government's appeal pending ( University of Colorado Boulder ISSS).

Within that framework, five realistic routes into space work exist:

• Roles without controlled data: software, data, analytics, sales, finance and operations at companies whose products are data or services, like the Planet roles without an export block.
• EAR-side engineering: commercial spacecraft and ground systems under 9A515, where a license for your nationality may be feasible.
• Employers that will license: those whose postings say "or eligible to obtain authorization", where a rare skill can justify the paperwork.
• University research: fundamental research that is ordinarily published, where you can do real space work and build a record.
• Work abroad: ESA if you hold a member-state nationality, or a company's sites outside the United States, as Rocket Lab's "US offices only" clause implies.

The longer route runs through status itself. A green card makes you a U.S. person under ITAR immediately ( 22 CFR 120.62), which opens almost every export-controlled space job, and naturalization then opens the clearance track. Many international engineers start in an EAR or non-controlled role, move to ITAR work once they hold permanent residence, and move into cleared programs after citizenship. That is a multi-year plan, but it is the plan that the regulations actually support.

What does not work is hoping the issue will not come up. Export checks happen before access is granted, the I-129 certification makes the employer state its conclusion in writing, and misrepresenting your status is far more damaging than the status itself. Say what you are early, ask the questions in section 6, and target the routes above. The aerospace engineer guide covers the degrees and specialties that transfer best between the controlled and uncontrolled sides of the industry.

17. Europe and the UK: ESA nationality rules and UK vetting

Europe has its own nationality gates, built on membership rather than export law. The European Space Agency has 23 Member States, with Cyprus, Slovakia, Latvia and Lithuania as Associate Members, Bulgaria, Croatia and Malta under cooperation agreements, and Canada sitting on the ESA Council under a cooperation agreement of its own ( ESA). Slovenia became the 23rd Member State on 1 January 2025 (same source).

ESA recruits only from those countries. For its Graduate Trainee programme, applicants must be citizens of a Member State, an Associate Member or a Cooperating State, and ESA answers the question "I am not a national of one of the ESA Member States. Can I still apply?" with "Unfortunately, this is not possible", adding that "your country of residence is not the determining factor" ( ESA Graduate Trainee FAQ). The exact list of eligible countries is published in the footer of each ESA vacancy, and the Junior Professional Programme is open to citizens of Member States, Associate Members or Canada ( ESA). Internships follow the same pattern ( ESA, find your path). For a U.S. citizen without a European passport, ESA staff jobs are therefore closed; for a European on a U.S. visa, ESA can be the more open door.

The United Kingdom runs national security vetting through United Kingdom Security Vetting, with five main levels: the Accreditation Check, the Counter Terrorist Check, Level 1B, Security Check (SC) and Developed Vetting (DV), all from CTC upward resting on the Baseline Personnel Security Standard ( GOV.UK). SC is for posts with long-term, frequent and uncontrolled access to SECRET assets and includes credit and Security Service record checks; DV is for frequent and uncontrolled access to TOP SECRET assets and adds a full review of personal finances and a detailed interview ( GOV.UK, clearance levels). An SC clearance is formally reviewed after 10 years, or 7 for some contractors, and a DV after 7 years, and the baseline guidance notes that "UK residency may affect the checks undertaken" (same source).

One rule follows U.S. technology overseas. A European company that receives ITAR or EAR data remains bound by the U.S. authorization it holds, which is why Planet's German subsidiary advertises its BIS license for export-controlled roles ( Planet Labs Germany posting) and why ITAR provides a specific exemption for transfers to dual and third-country nationals within an authorized foreign end user ( 22 CFR 126.18). Moving abroad changes which country's vetting you face, but it does not take you outside U.S. export law if the work touches U.S. controlled data. To apply this, check the nationality footer on each ESA vacancy, check whether a UK role names a vetting level, and ask any European employer whether the role touches U.S.-origin controlled data.

18. A decision checklist

This flowchart turns the rules above into the order a recruiter's or compliance officer's thinking usually follows. It starts from what the posting asks for, because that is the information you have before you apply.

The three gates in the order employers apply them

Before applying, five questions settle most cases. Each one maps to a gate and to a section of this guide, so a "no" or "not sure" tells you where to read.

1. Which gate is invoked: does the posting say "U.S. person", "U.S. citizen", "clearance", or nothing?
2. Your exact status: are you a citizen, green card holder, refugee, granted asylee, or on a temporary status?
3. ITAR or EAR: does the work touch launch vehicles or intelligence spacecraft (ITAR), or commercial spacecraft and ground systems (EAR)?
4. License willingness: does the posting say "or eligible to obtain authorization", and is your nationality on the denial list?
5. Clearance readiness: can you document seven years of history, and are your finances, foreign contacts and drug history in order?

The answers interact. A green card holder with a clean history is eligible for almost every export-controlled job and for no cleared ones, so the strategic question is whether to target uncleared ITAR work now and pursue citizenship for later. An H-1B holder whose nationality is licensable should concentrate on employers whose clauses mention authorization and on EAR-side roles. A citizen with a messy financial history should fix it before taking a cleared offer, not after, because the investigation reads the record as it stands on the day it runs.

Once the gates are clear, the remaining question is fit. Use the job board to filter for the roles your status opens, and the master guide for how to stand out once you are in the right pile. Everything in this checklist is general; for any specific offer, the employer's export compliance or security office is the authority, and the other career guides cover the roles themselves.

19. Questions people ask

Does ITAR require U.S. citizenship? No. ITAR requires a license before technical data is released to a foreign person, and it defines U.S. persons to include green card holders, refugees and asylees as well as citizens ( 22 CFR 120.62). Citizenship requirements in space jobs usually come from security clearances or government contracts, not from ITAR.

Is a green card holder a U.S. person for ITAR? Yes. Lawful permanent residents are named directly in the definition ( 22 CFR 120.62), so a green card holder can work on ITAR-controlled programs without a license. A green card does not, however, make you eligible for a regular security clearance.

Can refugees and asylees work on ITAR programs? Yes, once refugee status or asylum has been granted; both are protected individuals under 8 U.S.C. 1324b(a)(3) and therefore U.S. persons ( 8 U.S.C. 1324b). A pending asylum application does not count until it is granted.

Can I get a security clearance with a green card? Not a regular one. Non-citizens can receive only a Limited Access Authorization in rare cases where their expertise is urgently needed, and it is not valid for Top Secret, intelligence or communications security information ( 32 CFR 117.10(k)).

Can I apply for a security clearance on my own? No. A contractor may request eligibility only for its own employees or consultants who need access for a classified contract, and not to build a pool of cleared staff ( 32 CFR 117.10). The usual sequence is a conditional offer, then the SF-86.

How long does a clearance take? In the quarter to June 2026, the government's projected end-to-end average for the fastest 90 percent of new cases was about 146 days for High Risk cases, which include Top Secret, and 82 days for Moderate Risk cases, which include Secret ( PAC quarterly progress report, FY2026 Q3). Many people start work sooner on a preliminary determination.

Will past marijuana use stop me getting a clearance? Not automatically. Past recreational use is "relevant, but not determinative" ( Government Executive), but the SF-86 asks about use under federal law even where states allow it ( SF-86), and ongoing use, including state-licensed medical use, remains a serious problem after the April 2026 rescheduling ( Arnold & Porter).

Does dual citizenship disqualify me from a clearance? By itself, no; SEAD 4 says dual citizenship is not disqualifying "without an objective showing of such conflict or attempt at concealment" ( SEAD 4, Guideline C). Failing to report a foreign passport, or not using your U.S. passport at the border, can raise concerns.

Can an international student intern at a rocket company? Usually only in roles that do not touch controlled data, or where the company obtains a license, because launch vehicles are Category IV defense articles ( 22 CFR 121.1). University research that is ordinarily published is a more open route ( 22 CFR 120.34).

Do NASA jobs require U.S. citizenship? Civil service jobs, in practice, yes: competitive service appointments are limited to citizens and nationals except in rare cases ( OPM). Contractor and university roles at NASA centers can be open to foreign nationals, subject to NASA's badging and escort rules ( NPR 1600.4B, Chapter 4).

What happened to the DOJ lawsuit against SpaceX? The Justice Department moved to dismiss it in February 2025, and the administrative law judge dismissed it with prejudice on 24 February 2025, without any ruling on the merits ( Immigration Policy Tracking Project).

Does working for a space company abroad avoid ITAR? Only if the work does not involve U.S.-origin controlled data. Foreign companies that receive it operate under U.S. authorizations, as Planet's German subsidiary's BIS license shows ( Planet Labs Germany posting).

How this guide is researched

The rules in this guide were checked against the named regulations and agency pages on 29 October 2026: the ITAR (22 CFR parts 120 to 130) and the EAR (15 CFR parts 730 to 774) as published in the eCFR, State and Commerce rulemakings in the Federal Register, 32 CFR part 117, Executive Orders 12968 and 13526, SEAD 4, the Performance Accountability Council's FY2026 Q3 reports, NASA's NPR 1600.4B, OPM, USCIS, ESA and GOV.UK, together with court records and press reports for the SpaceX case and employers' own job postings read that day. This is general information, not legal advice. Before relying on it for a specific role, confirm with the employer's export compliance or security office.
