This bill proposes an amendment to the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 , specifically concerning the E-verify program. The core purpose is to expand the mandatory use of E-verify to all entities engaged in federal contracts. Under the new provision, every Federal contractor , including those working with executive or legislative branch agencies, and all their subcontractors at any tier , would be required to elect participation in the E-verify program. Furthermore, these entities must comply with all terms and conditions associated with their E-verify election, thereby strengthening employment eligibility verification for workforces involved in federal government projects.
