September 8, 2009 marked the effective date of the U.S. Citizenship and Immigration Services’ (USCIS) rule requiring certain federal contractors and subcontractors to use the E-Verify system to verify their employees’ eligibility to work in the United States if their contract includes the Federal Acquisition Regulation (FAR) E-Verify clause. The E-Verify FAR rule requires the use of the E-Verify system to cover federal contractors and subcontractors, including those who receive American Recovery and Reinvestment Act funds. Federal contracts awarded on or after September 8, 2009, and which are subject to rule, will include a clause committing government contractors to use E-Verify. Companies awarded a contract with the E-Verify clause on or after September 8, 2009 will be required to enroll in E-Verify within 30 days of the contract award date. With certain exceptions, E-Verify must be used to confirm that all new hires, whether employed on a federal contract or not, and existing employees directly working on these contracts are legally authorized to work in the United States.
