Joining the Army National Guard does not make you a U.S. citizen. Honorable service can make a green card holder eligible to apply for naturalization under special military provisions, but you still file Form N-400, pass the English and civics tests and take the Oath of Allegiance. This guide follows USCIS pages checked on October 21, 2026. Confirm your own case with a recruiter and USCIS before you rely on it.
Does joining the Army National Guard make you a citizen?
No. Service can make you eligible to apply, and USCIS decides. Under INA 329 you must show honorable service, the ability to read, write and speak English, knowledge of U.S. history and government, good moral character, and attachment to the Constitution. You file Form N-400 and take the Oath of Allegiance.

Which military naturalization law applies to Guard members now?
INA 329 applies, because it covers service during a designated period of hostilities. USCIS says the current period began on September 11, 2001, and continues until the President ends it by executive order. Honorable service in the Selected Reserve can qualify, and most National Guard members are in the Selected Reserve.
USCIS says it does not require proof of federal activation for a Guard applicant who served in the Selected Reserve during the designated period, and that members who serve honorably for any period of time during designated hostilities may be eligible (USCIS Policy Manual, INA 329). INA 328, which requires honorable service totaling at least 1 year, is a separate provision (USCIS military page).
What does INA 329 require?
USCIS lists honorable service during the designated period and, if you have separated, a separation under honorable conditions. You also need lawful permanent residence or physical presence in the United States when you enlisted, English, civics, good moral character for at least 1 year before filing, and attachment to the Constitution.
- A Form N-426, Request for Certification of Military or Naval Service, certified by the military if you are serving; a DD Form 214 or NGB Form 22 if you have separated (USCIS military page).
- INA 329 applicants are exempt from the general continuous residence and physical presence requirements (USCIS military page).
- USCIS cannot decide a current service member's application without a properly submitted N-426 (USCIS Policy Manual, INA 329).
How do you apply?
Ask your chain of command to certify Form N-426, then file Form N-400 under INA 329, online or on paper. There is no fee for naturalization applications under INA 328 or 329. USCIS takes your fingerprints, interviews you, tests your English and civics, and schedules the oath if you are approved.
- Get Form N-426 certified by the military (USCIS military page).
- File Form N-400, with no fee under INA 328 or 329 (USCIS military page).
- Give biometrics. Service members may do this at an application support center before filing; people stationed abroad can use FD-258 fingerprint cards (USCIS military page).
- Attend the interview and tests, then take the oath (USCIS military page).
Questions: USCIS Military Help Line, 877-CIS-4MIL (877-247-4645), Monday through Friday, 8 a.m. to 8 p.m. Eastern (USCIS military page).
What can block or reverse military naturalization?
Your discharge type, and after naturalization, fraud or an early other than honorable discharge. Only honorable and general discharges qualify; uncharacterized ones count only if issued on or before July 31, 2024. For people naturalized under the military provisions since November 23, 2003, an other than honorable discharge before 5 years of honorable service can lead to revocation.
Sources: USCIS Policy Manual, INA 329 and USCIS Policy Manual, revocation of naturalization. The 5-year rule applies after naturalization; it is not a minimum service time to apply. Confirm your situation with a recruiter and USCIS before you treat service as a citizenship plan.
