U.S. law requires companies to employ only individuals who may legally work in the United States – either U.S. citizens or foreign citizens who have the necessary authorization. This diverse workforce contributes greatly to the vibrancy and strength of our economy, but that same strength can also attract unauthorized employment.

E-Verify is administered by the U.S. Department of Homeland Security, the United States Citizenship and Immigration Services, Verification Division, and the Social Security Administration.

E-Verify is closely linked to Form I-9 and exists to strengthen the Form I-9 employment eligibility verification process that all employers, by law, must follow. Though all employers must verify their employees’ employment eligibility with Form I 9, participation in E-Verify is usually voluntary.


Why do people come to the United States illegally? They come here to work. The public can, and should, choose to reward companies that follow the law and employ a legal workforce.

The U.S. Department of Homeland Security is working to stop unauthorized employment. By using E-Verify to determine the employment eligibility of their employees, companies become part of the solution in addressing this problem.

Employment eligibility verification is not only good business — it’s the law.


More than 409,000 employers across the United States use E-Verify to check the employment eligibility of their employees, with about 1,300 new businesses signing up each week.

While participation in E-Verify is voluntary for most businesses, some companies may be required by state law or federal regulation to use E-Verify. For example, most employers in Arizona and Mississippi are required to use E-Verify. E-Verify is also mandatory for employers with federal contracts or subcontracts that contain the Federal Acquisition Regulation E-Verify clause.
