In an Executive Order dated June 6, 2008, President Bush ordered that all federal contractors will be required to use the E-Verify system to verify the employment eligibility of employees working on federal contracts. E-Verify is a internet-based system operated jointly by the Department of Homeland Security and the Social Security Administration, which allows employers to check applicant’s employment authorization on-line. While federal contractors are not yet required to use E-Verify, the requirement will go into effect 30 days following the publication of a final rule by the DHS.
