Qualifying immigrants who have served honorably on active duty in the U.S. Armed Forces and certain components of the National Guard and the Selected Reserve of the Ready Reserve, may apply for expedited citizenship processing under special wartime provisions in the Immigration and Naturalization Act.

To honor the service and sacrifices that these immigrants have made for their adopted nation, these troops can naturalize in overseas ceremonies instead of waiting until their return to the U.S.

The spouses and children of these military members may also naturalize abroad without having to return to the U.S. for any part of the process.
