Some employers around the nation have been using E-Verify to check the immigration status of employees for years. Operated by the Department of Homeland Security, the online system is designed to make it harder to hire unauthorized workers — and harder for those workers to find jobs.
While participation in the program has been voluntary since 1996, the immigration bill now in the Senate would make E-Verify mandatory.
