Men living in the U.S., citizen and non-citizens alike, are required by law to register with Selective Service at 18 years old.

Men who register with Selective Service remain eligible for federal student financial aid, state-funded student financial aid, federal employment, state employment, job training under the Workforce Innovation and Opportunity Act, security clearances, and U.S. citizenship for immigrant men. For more information, see Why Register. Selective Service accepts early registrations as young as 17 years and 3 months.

The Selective Service System has not now, or in the past, collected or shared any information which would indicate a man's immigration status, either documented or undocumented.
