To amend the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 to require all Federal contractors to participate in the E-verify program.

HR 2641 requires all federal contractors and subcontractors (at every tier) to elect participation in the E-Verify program, which checks the employment eligibility of new hires. This bill amends the 1996 Immigration Act to mandate that every contractor working with federal agencies must use E-Verify for all new employees. It directly affects businesses that contract with the federal government, including those providing services or goods to agencies. The key mechanism is the mandatory election to participate in E-Verify, replacing the current voluntary system for federal contractors.
