In general, you must be a U.S. citizen or national (residents of American Samoa and Swains Island) to work for the federal government, but there are some exceptions.

What are the exceptions for non-U.S. citizens?

In rare cases, a federal agency may:

• Hire a non-U.S. citizen into the excepted service or Senior Executive Service, if the annual Appropriations Act, the Immigration Law and the agency's internal policies allow it.
• Request approval to hire a non-U.S. citizen into the competitive service, if no qualified U.S. citizen is available.

How do I know if a job is open to a non-U.S. citizen?

Each job announcement lists a This job is open to section and a Qualifications section to help you understand if you fit the job's requirements. The This job is open to section will tell you whether or not a non-U.S. citizen is eligible for the job.

If you still have questions after reviewing the job announcement, contact the agency listed on the job announcement or read the full legal requirements for hiring U.S. citizens or non-U.S. citizens.

Legal requirements for hiring or not hiring a non-U.S. citizen

There are several legal orders that decide whether a federal agency may hire a non-U.S. citizen:

• Executive Order 11935 requiring citizenship in the competitive civil service.
• The annual appropriations act ban on paying aliens from many countries.
• The immigration law ban on employing aliens unless they are lawfully admitted for permanent residence or otherwise authorized to be employed.

Executive Order 11935 on the competitive civil service

Under Executive Order 11935, only United States citizens and nationals (residents of American Samoa and Swains Island) may compete for, and be appointed to, competitive service jobs. With Office of Personnel Management approval, agencies are permitted to hire non-citizens when there are no qualified citizens available. A non-citizen hired in the absence of qualified citizens may only be given an excepted appointment, and does not acquire competitive civil service status. He or she may not be promoted or reassigned to another position in the competitive service, except in situations where a qualified citizen is not available. The non-citizen may be hired only if permitted by the appropriations act and the immigration law.

Excepted service and Senior Executive Service

Some federal agencies (among them the United States Postal Service, the Tennessee Valley Authority and the Federal Bureau of Investigation), and some types of positions (for example, lawyers and chaplains) are exempt from competitive civil service hiring requirements. An agency may hire a qualified non-citizen in the excepted service or Senior Executive Service, if it is permitted to do so by the annual appropriations act and the immigration law and the agency's specific laws and internal policies. Many agencies have executive level positions in the Senior Executive Service.

Appropriations Act restrictions

Congress prohibits the use of appropriated funds to employ non-citizens within the United States. Certain groups of non-citizens are not included in this ban, including:

• Persons who owe permanent allegiance to the United States (for example, natives of American Samoa and Swains Island).
• Persons lawfully admitted for permanent residence and seeking citizenship as outlined in 8 U.S.C. 1324b(a)(3)(B).
• Persons admitted as refugees under 8 U.S.C. 1157 or granted asylum under 8 U.S.C. 1158 and have filed a declaration of intention to become lawful permanent residents and then citizens when eligible.
• Translators employed temporarily.
• People employed up to 60 days on an emergency basis in the field service.
• Non-resident aliens employed as wildland firefighters for not more than 120 days by the Department of the Interior or the U.S. Department of Agriculture, U.S. Forest Service, pursuant to an agreement with another country.
• Persons who were officers or employees of the U.S. government on December 16, 2009.

Also, some agencies are exempt from these restrictions.

Although the above groups are not prohibited from being paid from agency appropriated funds, they are still subject to the requirements of Executive Order 11935 listed above and to the immigration law as summarized below.

Immigration law requirements on employing citizens and aliens

For any work to be performed in the United States, immigration law requires private and public employers to hire only individuals who are eligible to be employed. Those individuals are:

• A citizen (either by birth or naturalization) or national of the United States,
• An alien assigned by the U.S. Citizenship and Immigration Services (CIS), Department of Homeland Security, to a class of immigrants authorized to be employed (aliens who are lawfully admitted for permanent residence by INS are the largest class of aliens in this category) or
• An individual alien who is expressly authorized by CIS to be employed.

Please contact the local CIS office with questions about an individual's citizenship, nationality, immigration status or eligibility for employment under the immigration law.

Although an alien may be authorized to work under the immigration laws, he or she is still subject to the requirements of Executive Order 11935 and appropriations act restrictions, as stated above.
