Q : Which employees should be verified through the system?

As a participant in E-Verify, employers are required to verify all newly hired employees, both U.S. citizens and non-citizens. Employers may not verify selectively, and must verify all new hires while participating in the program. The program may not be used to prescreen applicants for employment, go back and check employees hired before the company signed the MOU, or re-verify employees who have temporary work authorization.
