Summary

Current and former members of the U.S. armed forces may qualify for naturalization under special rules. INA 328 covers at least one year of honorable service. INA 329 covers honorable service during a designated period of hostilities and can remove the ordinary permanent-residence, age, continuous-residence, and physical-presence requirements in qualifying cases.

The period beginning September 11, 2001 remains designated as a period of hostilities for INA 329 as of August 15, 2026.

Eligibility

One year of service under INA 328

The applicant generally must be at least 18, have at least one year of honorable service, and, if separated, have separated under honorable conditions. The person must be a lawful permanent resident at the naturalization examination. Special residence and physical-presence treatment applies while serving or when filing within six months after separation; later filers may need to satisfy the ordinary five-year residence and 30-month physical-presence rules.

Service during hostilities under INA 329

The applicant must have served honorably during a designated period and, if separated, have separated under honorable conditions. The person generally must either have been a lawful permanent resident or have been physically present in the United States or another qualifying area when enlisted, reenlisted, extended service, or was inducted. No minimum service length, minimum age, or ordinary continuous-residence/physical-presence period applies, but good moral character, English, civics, constitutional attachment, and oath rules still matter unless another exception applies.

What This Route Allows

Eligible service members file Form N-400 without the ordinary filing fee and use certified military service evidence, generally Form N-426 for current service. USCIS can conduct parts of the process through military channels and has overseas procedures in qualifying cases.

Special provisions also exist for posthumous citizenship and for some spouses, children, and parents of deceased service members, but those are separate analyzes.

What This Route Is Not

Military service does not guarantee citizenship. The service branch must characterize the service as honorable for immigration purposes, and discharge character matters. Desertion, certain discharges, criminal or immigration history, false statements, and an alienage-based request for exemption or discharge can create serious bars.

Do not assume a recruiter, commander, DD-214 label, or length of service alone resolves eligibility. USCIS applies the statute and requires certified service records.

Next Steps

  1. Identify whether INA 328 or INA 329 fits the exact service dates and enlistment/admission facts.
  2. Obtain certified Form N-426 if currently serving, or DD-214/NGB records and all discharge documents if separated.
  3. Review good moral character, criminal, immigration, selective-service, and discharge issues before filing.
  4. Use the USCIS Military Help Line and installation legal-assistance resources for filing logistics.
  5. If separated under anything other than clearly honorable conditions, obtain individualized advice before relying on this route.
