“Under current law, all male U.S. citizens are required to register with Selective Service within 30 days of their 18th birthday. In addition, non-U.S.-citizen males between the ages of 18 and 25 (inclusive) living in the United States must register. This includes permanent residents (holders of Green Cards), refugees, asylees, and illegal aliens”
