The Selective Service System is an independent agency of the United States government that maintains information on those potentially subject to military conscription. 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.
