N-400 Military Naturalization: Expedited Citizenship Guide

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 — no scheduled appointment needed
• Military naturalization may be processed faster than many civilian N-400 cases, but USCIS does not publish a current official military-specific 4–8 month processing range on its military naturalization page. Check USCIS processing times and the Military Help Line for current case-specific updates.

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

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. Form N-400 is currently available to file online through a USCIS online account or by paper mail. If you file by paper, use the current USCIS Direct Filing Addresses for Form N-400; USCIS does not currently instruct all military applicants to mail every N-400 to the Nebraska Service Center.

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 both the English and civics tests. USCIS administers the 2025 civics test only to applicants who filed Form N-400 on or after October 20, 2025. That version draws from 128 questions, asks up to 20 questions, and requires 12 correct answers to pass. Applicants who filed before October 20, 2025 take the 2008 civics test.

Step 7: Oath of Allegiance

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

2025–2026 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): The test now draws from 128 questions instead of 100. You'll be asked 20 at your interview and must answer 12 correctly — up from 10 asked, 6 to pass.

Good moral character standards (August 15, 2025): USCIS issued policy guidance adopting a more rigorous, holistic good moral character review. In a September 17, 2025 USCIS news release, the agency also said it had resumed neighborhood investigations.
