N-400 for current and former service members
Military citizenship: your service may shorten the path
Military citizenship runs on two special rules, INA 328 and INA 329, and applicants under either pay no USCIS filing fee. We prepare your N-400, tell you exactly what the N-426 needs, and show you a report of the answers that could cause a problem before you pay.

Military naturalization
Which military rule fits your service?
Two laws cover military naturalization. The free eligibility check reads your dates and discharge and tells you which one applies.
- 01
Service during hostilities
You served honorably during a designated period of hostilities, which includes service from September 11, 2001 to the present. You skip the usual residence and physical-presence time, and a green card is not always required.
MOST FLEXIBLE INA 329Check eligibility - 02
One year of service in peacetime
You served honorably for at least one year at any time. This route generally needs a green card, and the residence rules depend on when you separated from service.
GREEN CARD NEEDED INA 328Check eligibility - 03
Less than honorable service
Honorable and general (under honorable conditions) discharges qualify. Other than honorable, bad conduct and dishonorable discharges do not. If you hold a green card you may still qualify the standard way once you meet the usual residence rules.

Common questions
Military citizenship, answered
What service members and veterans ask before they apply.
You file the same Form N-400 as everyone else, but under one of two special laws. INA 329 covers honorable service during a designated period of hostilities. INA 328 covers at least one year of honorable service at any time. Either way, some of the usual requirements are waived or reduced.
INA 328 is the peacetime rule. It asks for at least one year of honorable service, and you generally need to be a green card holder. INA 329 applies to service during designated hostilities, a list that includes September 11, 2001 to the present. Under INA 329 you do not need a set period of residence or physical presence in the U.S., and you do not always need a green card.
USCIS charges no filing fee for naturalization under INA 328 or 329. Immiva charges its own fee of $199 for preparing and reviewing your N-400, and you pay it only after you have seen your report.
Under INA 329, not always. You must either be a lawful permanent resident or have been physically present in the U.S., or on a qualifying U.S. vessel or territory, when you enlisted, reenlisted, extended your service, or were inducted. Under INA 328 you must be a green card holder at your interview.
Form N-426 is the certification of your military service, signed by an authorized official. If you are serving when you file, it goes in with your N-400. Immiva does not prepare the N-426. We prepare the N-400, and our report tells you what the N-426 needs and who has to sign it. Veterans submit a copy of their DD-214, NGB-22 or other discharge papers instead.
Honorable and general (under honorable conditions) discharges qualify. Other than honorable, bad conduct and dishonorable discharges disqualify you from both military paths. If you are a green card holder, you may still qualify the standard way after the usual residence period. Our check says so plainly, and an immigration attorney or a veterans service organization can look at a discharge that is unclear.
Yes. Currently serving members can apply, and under INA 329 your service during the current period of hostilities can be enough. Many installations have a USCIS liaison who can help you get the N-426 signed.
The N-426 if you are serving, or your DD-214, NGB-22 or other discharge papers for every period of service if you have separated. After that, whatever your answers call for: green card copy if you have one, travel dates, and records for any arrest. We build the list from your answers. See the full N-400 checklist
