Am I eligible to file Form Application for Naturalization (Form N-400) based on qualifying military service?
A. You may file an Application for Naturalization (Form N-400), even if you are honorably separated from the military, based upon eligibility under section 328 or 329 of the INA. If you served honorably in any branch of the U.S. Armed Forces for a period exceeding one year, you may claim eligibility under section 328 of the INA. If you served during a specified period of hostility, to include September 11, 2001, to present, you may claim eligibility under section 329 of the INA regardless of the length of service.
