Naturalization Through Military Service
Immigrants who have served in the US Armed Forces during a time of hostilities are eligible for expedited naturalization.
Those that have served honorably since September 11, 2001 are eligible to immediately apply for naturalization. This is also true for those who served honorably in a prior conflict (World War II, Korean War, Vietnam War, Gulf War, etc.)
In 2008, the Department of Defense established the Military Accessions Vital to the National Interest (MAVNI) program.
Spouses and children of members of the US Armed Forces are also eligible for immigration benefits.
