"Males 18-25 Remember to Register with the Selective Service System. If you don't, you could be throwing away some important opportunities and benefits such as state-funded student financial aid, federal employment, state employment, security clearance for contractors, job training under the Workforce Innovation and Opportunity Act (formerly known as the Workforce Investment Act), and U.S. citizenship for immigrant men. Contact Ms. Salima Virani, your Selective Service System Representative for more information." Selective Service System is not a recruiting agency. They will not pass on their information for Recruiters.
