E-Verify

E-Verify is an Internet-based system that allows an employer, using information reported on an employee's Form I-9, Employment Eligibility Verification, to determine the eligibility of that employee to work in the United States. The use of E-Verify is limited to determining the employment eligibility of new hires only. There is no charge to employers to use E-Verify. The E-Verify system is operated by the Department of Homeland Security in partnership with the Social Security Administration.

E-Verify is mandatory for employers with federal contracts or subcontracts that contain the Federal Acquisition Regulation (FAR) E-Verify clause and employers in certain states.
