Federal law requires that men who are at least 18 years old, but not yet 26 years old, must be registered with Selective Service. This includes all male non-citizens within these age limits who permanently reside in the United States. Men with "green cards" (lawful permanent residents) must register. Men living in the United States without USCIS documentation (undocumented aliens) must also register. But men cannot register after reaching age 26.

Why Do I Need to Register with the Selective Service?

Failure to register for the Selective Service may (in certain instances) make you ineligible for certain immigration benefits, such as citizenship.

For instructions on registering with Selective Service as an immigrant, please see the Selective Service System's Registration Information.

If you would like to confirm that you or someone else is registered with Selective Service, please see the Selective Service System's Check a Registration.
