Can Green Card Holders Work for the Federal Government?

Green card holders can work for the federal government, but only in a narrow band of positions. Most federal jobs sit in the competitive service, which is reserved by executive order for U.S. citizens and nationals. Lawful permanent residents can apply for excepted service roles, jobs at agencies outside the competitive framework like the U.S. Postal Service, and the rare competitive opening where no qualified citizen is available. On top of that, an annual appropriations provision requires that green card holders be actively pursuing citizenship to be paid with federal funds.

Why Most Federal Jobs Are Closed to Non-Citizens

The competitive service covers most federal hiring, from entry-level administrative work to mid-career professional roles across dozens of agencies. Executive Order 11935 bars anyone who is not a U.S. citizen or national from taking a competitive exam or receiving a competitive service appointment. Residents of American Samoa and Swains Island qualify as nationals; green card holders do not.¹

The implementing regulation, 5 CFR 338.101, allows non-citizen appointments only “in rare cases” and only when no statute prohibits the hire.² When one of these rare exceptions is made, the non-citizen doesn’t gain competitive civil service status. The person receives an excepted appointment instead and cannot be promoted or reassigned into other competitive service positions unless, again, no qualified citizen is available for that role.¹ In practical terms it’s a dead end, not a stepping stone into a full federal career.

You Must Be Actively Pursuing Citizenship to Be Paid

Even for positions that don’t require citizenship, a separate rule catches many applicants off guard. Each year’s Consolidated Appropriations Act restricts which non-citizens can be paid with federal funds. For fiscal year 2026, the law permits compensation for a limited set of categories:³

Lawful permanent residents who are actively pursuing naturalization as defined under 8 U.S.C. 1324b(a)(3)(B).
Refugees admitted under 8 U.S.C. 1157 and asylees granted status under 8 U.S.C. 1158 who have declared intent to become permanent residents and then citizens.
Translators hired on a temporary basis.
Emergency field workers on temporary appointments not exceeding 60 days.
Nonresident wildland firefighters employed by the Department of the Interior or the USDA Forest Service for up to 120 days under international agreements.

The “seeking citizenship” requirement has real teeth. Under 8 U.S.C. 1324b(a)(3)(B), a green card holder loses protected status if they fail to apply for naturalization within six months of becoming eligible. If you applied but haven’t been naturalized within two years, you need to show you’re still actively pursuing it. Time spent waiting on USCIS processing doesn’t count against you, but abandoning the process does.⁴

The practical takeaway is simple: if you’re a green card holder eyeing federal employment, file Form N-400 as soon as you’re eligible. Waiting can disqualify you from being paid even when an agency wants to hire you.

Where Green Card Holders Actually Get Hired

The excepted service operates outside the competitive hiring framework and is the most realistic route in. These positions are excluded from competitive service rules by statute, executive order, or OPM regulation.⁵ An agency can hire a qualified non-citizen into an excepted role when the agency’s own policies allow it, the annual appropriations act permits it, and immigration law authorizes the person to work.

Some agencies and occupations sit entirely outside the competitive service framework. USAJOBS lists the U.S. Postal Service, the Tennessee Valley Authority, and the FBI as examples, along with certain occupations like lawyers and chaplains.¹

Defense Science and Technology Reinvention Laboratories have flexibility to bring on foreign-born talent for research and technical roles, though a 2022 Department of Defense report to Congress noted that lengthy security processing times make this “practically infeasible” in many cases.⁶

The U.S. Postal Service

USPS is one of the largest federal employers that openly accepts lawful permanent residents. Under USPS policy, green card holders are eligible for all career and noncareer positions at EAS-19 and below, which covers most postal jobs including mail carriers, clerks, and mail handlers. Positions at EAS-20 and above, generally management-level roles, require prior approval from the area vice president.⁷

One important boundary: people with only asylum status, refugee status, or conditional permanent resident status are not eligible for USPS employment. You need a full, unconditional green card. The screening happens early, and your answer on PS Form 2591 about citizenship status determines whether you continue in the hiring process at all.⁷

Security Clearances Are a Hard Wall

Many federal jobs require access to classified information, and this is where green card holders hit the hardest limit. Executive Order 12968 restricts security clearance eligibility to U.S. citizens whose background investigation shows loyalty, trustworthiness, and freedom from conflicting allegiances.⁸ Expertise and good character don’t get around this for a standard clearance.

In rare circumstances, a non-citizen with special expertise can receive a Limited Access Authorization, capped at the Secret level and tied to specific programs.⁹ Under EO 12968, the access can’t exceed what the U.S. government has determined is releasable to the country where the person holds citizenship, and investigators must be able to appropriately cover the prior ten years of the person’s life.⁸ LAAs are genuinely uncommon and aren’t something to plan a career around.

Not every sensitive job requires a full clearance. Public trust positions, designated as moderate or high risk based on their impact on agency operations, require a suitability or fitness determination rather than a national security clearance. Whether a green card holder qualifies depends on the specific agency and position, since agencies set their own eligibility standards.

Selective Service Registration for Male Applicants

Male green card holders between 18 and 25 must register with the Selective Service System within 30 days of arriving in the United States or within 30 days of their 18th birthday, whichever comes later.¹⁰

Failing to register has direct consequences. Under 5 U.S.C. 3328, anyone born after December 31, 1959, who was required to register but did not is ineligible for appointment to any executive agency position. If you missed the window, you aren’t automatically disqualified, but you must show by a preponderance of the evidence that the failure wasn’t knowing or willful.¹¹ Registration is free and takes minutes online. The cost of skipping it can be your entire federal career.

How to Find Postings You Can Actually Apply To

USAJOBS.gov is the central portal for federal jobs. On any listing, look at the “Who May Apply” section. If it says “United States Citizens,” green card holders cannot apply for that role. Postings open to non-citizens will sometimes flag “Excepted Service” or specifically mention eligibility for lawful permanent residents.

A few things save time:

Filter by hiring path. USAJOBS lets you narrow to categories like excepted service.
Check agency career sites directly. USPS, TVA, and others use their own boards with clearer eligibility language.
Read the full announcement, not just the summary. Citizenship requirements sometimes appear only in the qualifications section.

Be accurate about your immigration status. Misrepresenting citizenship on a federal application is grounds for termination and potential criminal liability.

Benefits Come With the Job, Not the Passport

Green card holders in federal positions generally receive the same benefits as their citizen colleagues. The Federal Employees Health Benefits Program keys eligibility to appointment type rather than citizenship. The Thrift Savings Plan works the same way, and non-citizen federal employees can contribute and receive agency matching contributions. Retirement benefits under FERS follow the same pattern. What matters is whether the appointment type qualifies.

File for Naturalization Early

For green card holders serious about a federal career, naturalization is the single step that removes nearly every barrier. Citizenship opens the full competitive service, security clearances at all levels, and positions across every agency, and it eliminates the annual appropriations act question entirely. Most green card holders become eligible to apply after five years of permanent residence, or three years if married to a U.S. citizen.

Filing N-400 as soon as you’re eligible does double duty. It satisfies the appropriations act’s “seeking citizenship” requirement now, and it puts you on track to be a citizen when the right position opens up. Green card holders already working in federal excepted positions don’t gain competitive status through their appointment. Naturalization is what changes that.¹
