As of September 8, 2009, all federal contractors and subcontractors are now required to utilize the controversial E-Verify system to confirm an employees right to work legally in the United States.  In addition, those companies receiving stimulus funds will be required to implement E-Verify.  The controversy arises from the fact that the administration continues to expand the use of E-Verify without correcting the defects in the database system.  There is a belief that this faulty system will lead to discrimination against US workers who are perceived to be foreign born.  Please see the following Federal resources for guidance on E-Verify.
