Form I-9 And E-Verify

Employers verify each worker's identity and employment eligibility by completing the Form I-9, Employment Eligibility Verification at the time of hire. U.S. Citizenship and Immigration Services (USCIS), in the Department of Homeland Security (DHS), publishes the Form I-9 and accompanying instructions. Some employers also use E-Verify, an electronic system that compares a worker’s Form I-9 information with government databases to verify employment eligibility.

Federal law requires employers to follow Form I-9 and E-Verify rules consistently, regardless of an employee's citizenship, immigration status, or national origin. This anti-discrimination law is found at 8 U.S.C. § 1324b. The regulations for this law are at 28 C.F.R. Part 44.

The Form I-9 instructions explain that employees can present any documentation from the Lists of Acceptable Documents. At the time of hire, all employees can choose to present either an unexpired List A document, or an unexpired List B document together with an unexpired List C document. The Form I-9 instructions tell employers to accept all documents that are sufficient to complete Form I-9 as long as they reasonably appear to be genuine and to relate to the employee. For example, under the Lists of Acceptable Documents, attached to the Form I-9, individuals may present a valid U.S. driver's license and unrestricted Social Security card to satisfy Form I-9 requirements. Under the law that the Immigrant and Employee Rights Section (IER) enforces, employers are not allowed to request more or different documents than are required to establish a worker's identity and eligibility to work in the United States, request a specific document or reject documents that appear to be reasonably genuine on their face based on a worker's citizenship status or national origin. You can learn more by contacting IER and at 8 U.S.C. § 1324b(a)(6). For example, under this part of the law employers must not require lawful permanent residents to produce a Permanent Resident, also known as a "green card," and must not require U.S. citizens who appear "foreign" to produce a birth certificate. If the Form I-9 instructions require an employer to reverify an employee the instructions allow the employee to present any valid List A document or List C document for reverification.

Employers that participate in the E-Verify program must use E-Verify consistently and without regard to an employee’s citizenship, immigration status, or national origin to avoid violating 8 U.S.C. § 1324b or the E-Verify rules. Discrimination in the E-Verify process, such as requiring a DHS-issued document from all non-U.S. citizens to create an E-Verify case, violates 8 U.S.C. § 1324b and the E-Verify rules.
