Applicants for U.S. citizenship generally must show that they have lived in the U.S. on a green card for five years (just 3 years for a spouse of a U.S. citizen); can read, write and speak English; understand U.S. history and government; and are persons of good moral character. Elderly green card holders who have lived in the United States for long periods may be eligible to waive the English requirement and take the civics exam in their native language.
Citizenship for Military Members & Dependents
Members and veterans of the U.S. armed forces, and their dependents may be eligible for citizenship under special provisions of law. Members of the U.S. armed forces and their dependents (spouses and children) may be eligible for expedited and overseas processing of their naturalization applications.
Family Based Survivor Benefits (for Relatives)
Immediate relatives of U.S. armed forces members who die as a result of combat while in an active duty status may be eligible for certain “survivor” immigration benefits, including citizenship.
