Honorable active-duty service in the U.S. armed forces during a designated period of hostility allows an individual to naturalize without being required to establish any periods of residence or physical presence in the United States. A Servicemember who was in the United States, certain territories, or aboard an American public vessel at the time of enlistment, re-enlistment, extension of enlistment or induction, may naturalize even if he or she is not a lawful permanent resident.
On July 3, 2002, the president issued Executive Order 13269 establishing a new period of hostility for naturalization purposes beginning Sept. 11, 2001, and continuing until a date designated by a future Executive Order. Qualifying members of the armed forces who have served at any time during a specified period of hostility may immediately apply for naturalization using the current application — Form N-400 — "Application for Naturalization." Additional information about filing and requirement fees and designated periods of hostility are available on the U.S. Citizenship and Immigration Services (USCIS) Web site at www.uscis.gov.
