Employers now have no excuse for hiring a worker and not knowing whether he's an American or not. Any employer can go to this website, which is part of the US Social Security Administration, register a User ID and password, and check as many Social Security numbers as he needs to check. An employer can check a single employee, or he can check up to 10 names at a time, and get instant results. And he can upload a file with up to 250,000 names and receive confirmation by the next day.
