Most MALE U.S. citizens and MALE immigrant non-citizens between the ages of 18 and 25 are required by law to have registered within 30 days of their 18th birthdays and must notify Selective Service within ten days of any changes to any of the information they provided on their registration cards, like a change of address.
Registration for Selective Service is also required for various federal programs and benefits, including student loans (such as FAFSA), job training, federal employment, and naturalization.
The selective service registration requirement must require women to register or suffer the same penalty or be repealed once and for all.
