What Is the Purpose of This Form?

The principal purpose of this form is to solicit information to secure a duly authenticated certification of honorable active duty service from the U.S. Government Executive Department, under which you served or are serving, to satisfy statutory requirements for naturalization as a U.S. citizen.

Submission of the information is voluntary. If your U.S. Social Security number requested on the form is not provided, no right, benefit or privilege will be denied for such failure. However, as military records are indexed by such numbers, verification of your military service may prove difficult.

If you are applying for naturalization under Sections 328 or 329 of the Immigration and Nationality Act, you should submit this form and Form G-325B, Biographic Information, with your Form N-400, Application for Naturalization, to U.S. Citizenship and Immigration Services (USCIS).

What Is Our Authority for Collecting This Information?

Our authority for collecting the information requested on this form is contained in Sections 328 and 329 of the Immigration and Nationality Act of 1952 (8 U.S.C. 1439 and 1440).

All or part of the information solicited may as a matter of routine use be disclosed to courts exercising naturalization jurisdiction and to other Federal, state, local and foreign law enforcement and regulatory agencies, the Department of Defense, including any component thereof, Selective Service System, Department of State, Department of the Treasury, Central Intelligence Agency, Interpol and individuals and organizations that process the application for naturalization, or during the courses of investigation, to elicit further information required by USCIS to carry out its functions.

Information solicited that indicates a violation or potential violation of law, whether civil, criminal or regulatory in nature, may be referred as a routine use to the appropriate agency, whether Federal, state, local or foreign, charged with the responsibility of investigating, enforcing or prosecuting such violations.
Failure to provide any or all of the solicited information may delay the naturalization process or result in a failure to locate military records or prove qualifying military service.
