Can Non-Citizens Get Security Clearance? The LAA and Its Limits

Non-citizens generally cannot get a U.S. security clearance. Executive Order 12968 restricts eligibility to United States citizens who pass a background investigation into their loyalty, trustworthiness, and freedom from conflicting foreign allegiances.¹ There is one narrow workaround, the Limited Access Authorization, which lets a non-citizen touch certain classified information up to the Secret level when no qualified American is available. It is not a clearance, and it is granted sparingly.

Why Citizenship Is the Baseline Rule

Executive Order 12968, signed in 1995, is the governing policy. Section 3.1(b) says eligibility for access to classified information “shall be granted only to employees who are United States citizens” who have completed an appropriate investigation and whose history shows loyalty, honesty, reliability, and freedom from conflicting allegiances.¹ It applies at every classification level from Confidential through Top Secret, and it covers federal civilian employees, military personnel, and contractor staff alike.

Citizenship on its own doesn’t earn a clearance; it just opens the door to the process. Any doubt about an applicant is resolved in favor of national security rather than the individual.² Without citizenship, the standard route is effectively closed.

The Limited Access Authorization

The one meaningful exception is the Limited Access Authorization, or LAA, set out in 32 CFR 117.10(k). An LAA is not a security clearance. It is a temporary, project-specific authorization that permits a non-citizen to access classified information up to Secret. When the underlying contract or project ends, the authorization ends with it.³

The regulation isn’t limited to green card holders. It uses the broader term “non-U.S. citizens,” which includes lawful permanent residents and other non-citizens with appropriate legal status. In practice, though, three conditions all have to be satisfied:

The non-citizen must have unique or unusual expertise urgently needed for a specific government contract.
A cleared or clearable U.S. citizen cannot be readily available to fill the role.
A senior government official responsible for the contract must endorse the request.

Contractors have to exhaust the possibility of filling the role with a citizen before the government will even consider an LAA request.³ This is why LAAs are rare.

What an LAA Does Not Cover

Even after it’s granted, an LAA carries hard limits. The regulation puts entire categories of classified information off-limits to LAA holders no matter what the project needs:³

Top Secret information. LAAs cap at Secret.
Intelligence information from the intelligence community.
Communications security (COMSEC) material, including encryption keys and codes.
Restricted Data and Formerly Restricted Data, meaning nuclear weapons-related information under the Atomic Energy Act.
Third-party government information provided to the U.S. in confidence by a foreign government.
Any classified material not formally approved for release to the applicant’s country of citizenship.

NATO material has a separate track. A citizen of a NATO member nation may access NATO-classified information if the home country provides a NATO security clearance certificate, and the access is confined to work on a specific NATO contract.³

For the intelligence community, access to Sensitive Compartmented Information requires U.S. citizenship as a threshold. The Director of National Intelligence can grant exceptions, but only on a letter showing compelling national security need.⁴

How an LAA Actually Gets Requested

You cannot apply on your own. A U.S. government agency or a cleared defense contractor has to sponsor the request, and the process only begins after a conditional job offer for a position that requires access to classified information.⁵

The main document is DD Form 3134, “Limited Access Authorization for Aliens and Foreign Nationals.” The sponsoring contractor prepares it. The form has to describe the classified work involved, give a compelling reason a cleared U.S. citizen cannot do the job, lay out a plan for controlling the non-citizen’s access to secure areas, and commit to an annual assessment of continued trustworthiness.⁶ Supporting documents typically include proof of foreign citizenship such as a passport, a government disclosure determination or State Department export license, and a foreign security clearance certificate where one exists.⁷

You will also complete Standard Form 86, the detailed personal history questionnaire covering residency, employment, foreign contacts, and financial records. Investigators then verify the record, interview references, and check databases. An adjudicator reviews the file and decides whether granting access is consistent with national security.

How Long to Expect

Security clearance investigations are slow, and foreign ties stretch the timeline further. A standard Secret clearance typically takes about 60 to 90 days in straightforward cases and four to six months when the file is more complex. Top Secret investigations run roughly 90 to 180 days in simple cases and six months to a year when complications appear. Cases involving foreign contacts, overseas residency, or dual citizenship sit firmly in the complex bucket.

LAA requests add work on top of that. Before any investigation opens, the sponsoring contractor has to assemble the DD Form 3134 package, obtain the disclosure determination or export license, and submit a Technology Control Plan to the Defense Counterintelligence and Security Agency for approval.⁷ All of that runs before the investigation itself begins. Plan for a longer wait than a citizen going through a standard clearance would face.

If You Are a Naturalized Citizen

Some readers asking this question have already naturalized. If you have become a U.S. citizen, you are fully eligible for every level of clearance on the same legal footing as someone born in the country. Executive Order 12968 draws no distinction between natural-born and naturalized citizens.¹

The practical reality is that naturalized applicants tend to face more questions during the investigation because their history includes foreign countries, foreign contacts, and sometimes dual citizenship. None of that is an automatic disqualifier, but it triggers closer examination under the foreign influence and foreign preference guidelines.⁸ Taking the oath of citizenship does not automatically cancel a foreign citizenship you already hold, so be prepared to discuss whether you would renounce it if asked. The strongest position under the guidelines is dual citizenship derived solely from a parent or place of birth, with no active exercise of the foreign citizenship such as using a foreign passport, voting abroad, or serving in a foreign military.

If You Apply and Are Denied

A denial is not the end of the road. Executive Order 12968 sets out a structured appeal process. You must receive a written explanation of the denial that is as detailed as national security allows, and within 30 days of asking, you are entitled to copies of the documents and reports the decision relied on.¹

You can reply in writing and request a review of the decision.
You may hire an attorney or other representative at your own expense.
You get the opportunity, at some stage of the process, to appear in person before an adjudicative authority other than the investigating agency and present documents and information.
You can appeal in writing to a panel of at least three members, two of whom must come from outside the security field. The panel’s written decision is final unless the agency head exercises the appeal authority personally.

For contractor employees, the Defense Counterintelligence and Security Agency handles appeals through its Security Review Proceedings. After a Statement of Reasons is issued, you can submit a written response and elect a personal appearance with a senior adjudicator.⁹ Your agency or company security office can point you to the specific procedures that apply.
