E-Verify is an Internet-based system operated by Department of Homeland Security (DHS/U.S. Citizenship and Immigration Services (USCIS) in partnership with the Social Security Administration (SSA). E-Verify is currently free to employers and is available in all 50 states. E-Verify provides an automated link to federal databases to help employers determine employment eligibility or work authorization of new hires and the validity of their Social Security numbers.Employers or “Designated Agents” (e.g., payroll companies) must register online and agree to the terms of participation to use E-Verify. [Registration includes agreeing to the DHS/Immigrations and Customs Enforcement (ICE) Memorandum of Understanding (MOU). A discussion of the ICE E-Verify MOU is outside the scope of this post.]E-Verify will soon be required of all federal contractors. DHS is now promulgating “final” E-Verify regs. I present an E-Verify overview and update in this post.
