Fact Sheet: Naturalization in the U.S. Armed Forces

The United States allows individuals who are not citizens to join the U.S. Armed Forces as enlisted members, a policy with a long-standing history. As a part of this tradition, the United States has adopted policies that allow enlisted members of the armed forces who are not citizens to naturalize more quickly.
