You are exempt from Selective Service registration if you can prove you were continuously institutionalized or confined from 30 days before you turned 18 through age 25. If you were released for any period longer than 30 days during this window, you were required to register with the Selective Service System.
For Selective Service to determine this exemption, the following supporting documentation is needed when you mail your status information letter request form:
- Proof that your dates of confinement or institutionalization are accurate
- Proof that you were continuously incarcerated, or never released for any period of 30 days or longer.
