Does military service make me a U.S. citizen automatically?

No. Service doesn't confer automatic citizenship at any point, even after 20 or more years. You must file Form N-400, complete the interview and testing, and take the Oath of Allegiance. Use the N-400 eligibility checker to confirm your eligibility path before filing.

How much does it cost to apply for citizenship through the military?

$0. Military applicants under INA §328 or §329 pay no filing fee for Form N-400, Form N-426, or the N-336 appeal hearing if denied. Civilians pay $760 by paper or $710 online. Read more about N-400 costs if your spouse is applying through the civilian track.

What is Form N-426 and who needs to submit it?

Form N-426 is the Request for Certification of Military or Naval Service. Currently serving members must submit it with their N-400, signed by an O-6 or above. Veterans with a DD-214 or other discharge documentation don't need it. See the full list of what to bring to your citizenship interview.

Can I apply for citizenship while deployed overseas?

Yes. Service members stationed abroad can complete the process overseas. Two domestic field offices oversee these cases: the Guam Field Office for the Asia/Pacific region and the Washington Field Office for Europe, the Middle East, and Africa. They coordinate with the Department of Defense on a video-facilitated interview location. If you're applying based on former military service, you must complete the interview and Oath of Allegiance in the United States.

How long does military naturalization take right now?

There's no official military-specific estimate. USCIS prioritizes military cases, and they often move faster than civilian N-400s, but timing varies case by case. Check the USCIS processing times tool or call the Military Help Line for an update on yours.

N-400 Military Naturalization: Expedited Citizenship Guide

Serving in the U.S. armed forces puts you on a faster, cheaper path to citizenship — but you still have to apply.

Written byAlicja

Military members and veterans can apply for U.S. citizenship through Form N-400 with advantages over civilian applicants: no filing fee, waived residence requirements in most cases, and faster processing. But service alone doesn't make you a citizen — you still need to file, interview, and pass.

Does Military Service Automatically Give You Citizenship?

No. USCIS flags this as the most common misconception about military naturalization. Time in uniform doesn't make you a citizen, no matter how long you've served.

What service does give you:

A $0 filing fee (vs. $760 for civilian paper filers)
Waived continuous residence and physical presence requirements in most cases
Walk-in biometrics using your military ID, with no scheduled appointment needed
Typically faster processing than the civilian track, though USCIS doesn't publish a separate military timeline

You still need to file Form N-400, pass the English and civics tests, attend an interview, and take the Oath of Allegiance.

Your Two Paths: INA §328 vs. INA §329

Military members qualify under one of two statutes depending on when and how they served.

INA §328: Peacetime Service

You qualify under INA §328 (8 CFR Part 328) if you've served honorably for at least 1 year in any branch: Army, Navy, Marines, Air Force, Coast Guard, Space Force, or federally recognized National Guard.

Requirements:

At least 1 year of honorable service
Must hold a green card (LPR status) at time of interview
Good moral character for the past 5 years
At least 18 years old
Pass the English and civics tests

If you file while still serving or within 6 months of honorable separation, the standard 5-year continuous residence and physical presence requirements are waived (USCIS Policy Manual, Vol. 12, Part I, Ch. 2).

INA §329: Service During Hostilities

You qualify under INA §329 (8 CFR Part 329) if you served honorably during a designated period of hostilities. The current period runs from September 11, 2001 through the present, per Executive Order 13269.

Requirements:

Any amount of honorable active-duty or Selected Reserve service during a designated period
Green card NOT required. You qualify if you were physically present in the U.S. at enlistment, or if you later became an LPR
Good moral character for only 1 year (not 5)
No minimum age requirement
Fully exempt from all residence and physical presence requirements

	INA §328 (Peacetime)	INA §329 (Hostilities)
Service required	≥ 1 year	Any amount
Green card required?	Yes	No (if present at enlistment)
Residence waived?	Yes, if filing within 6 months	Fully exempt
Moral character period	5 years	1 year
Minimum age	18	None

How to Apply for Military N-400: Step by Step

Step 1: Confirm your eligibility path

Figure out whether you're filing under INA §328 or §329. This affects which checkboxes you select in Part 1 of Form N-400 and what documents you need.

Step 2: File Form N-400

Military applicants use the same Form N-400 as civilians. There's no separate military version. You can file online through a USCIS online account or by paper. If you file by paper, mail your package to the dedicated military address at the Chicago Lockbox (USCIS, Attn: Military N-400, P.O. Box 4446, Chicago, IL 60680-4446), listed on the USCIS direct filing addresses page.

Step 3: Submit Form N-426 (if currently serving)

If you are currently serving, you must include a signed and certified Form N-426 with your N-400. USCIS states that only authorized military personnel may certify Form N-426; certification authority is generally an officer in pay grade O-6 or above, or the civilian equivalent, subject to your service branch's policy.

Veterans with a DD Form 214, NGB Form 22, or other official discharge documents don't need N-426, per Policy Alert PA-2023-09 (March 2023). Include your discharge paperwork instead.

Step 4: Gather your documents

Along with N-400 and N-426 (if applicable), you'll typically need:

Copy of your green card (§328 applicants)
Military service records or DD-214
Two passport-style photos, but only if you reside outside the United States
Court records for any arrests or convictions

The N-400 document checklist covers everything to include.

Step 5: Biometrics

USCIS allows current and former service members to submit fingerprints at a USCIS Application Support Center in the United States before filing Form N-400. Bring your A-Number and evidence of current or prior military service, such as a military ID, official orders, enlistment contract, or discharge documents.

Step 6: Interview and civics test

You'll attend an interview and take the English and civics tests. N-400s filed on or after October 20, 2025 get the new 2025 civics test; earlier filings get the 2008 version. Our 128 civics questions study guide covers the current format and every question.

Step 7: Oath of Allegiance

If approved, you take the oath, often the same day as your interview at military ceremonies.

2025 and 2026 Policy Changes That Affect Military Applicants

Several updates took effect in the past year.

Uncharacterized discharges (effective guidance issued September 26, 2025): USCIS now states that an uncharacterized discharge issued before August 1, 2024 meets the separation 'under honorable conditions' requirement for military naturalization, while an uncharacterized discharge issued on or after August 1, 2024 does not.

New civics test (October 2025): Applications filed on or after October 20, 2025 take a tougher test drawn from a 128-question pool instead of the old 100.

Good moral character standards (August 15, 2025): USCIS issued policy guidance adopting a more rigorous, holistic good moral character review. A separate memo issued August 22, 2025 (PM-602-0189) resumed neighborhood investigations of naturalization applicants; reports indicate USCIS began conducting them in November 2025.
