The start date for the mandatory E-Verify program for federal contractors and subcontractors is now set for September 8, 2009. Further postponements are not expected. The U.S. Citizenship and Immigration Services has posted a Frequently Asked Questions page to help contractors understand the new requirements, and I highly recommend that all employers with federal contracts or subcontracts read it. All employers are permitted to participate in E-Verify, but federal contractors and subcontractors who do not comply risk debarment (loss of their ability to obtain federal contracts and subcontracts).
