E-Verify: DHS Employment Eligibility Verification Program
E-Verify is a web-based system administered jointly by the Department of Homeland Security (DHS) and the Social Security Administration (SSA) that allows employers to confirm the employment eligibility of newly hired workers in the United States. The program operates as an extension of the paper-based Form I-9 process mandated by the Immigration Reform and Control Act of 1986. Understanding E-Verify's scope, mechanics, and decision thresholds is essential for employers navigating federal and state compliance obligations. The DHS E-Verify program page provides additional program-level context within the broader DHS framework.
Definition and scope
E-Verify is an internet-based employment eligibility verification system that cross-references information from an employee's Form I-9 against federal records held by DHS and SSA. The program is operated by U.S. Citizenship and Immigration Services (USCIS), a component agency of DHS.
As of 2023, E-Verify enrolled more than 1 million employers, according to USCIS program data, making it the largest electronic employment eligibility verification program in the United States. Participation is mandatory for federal contractors subject to the Federal Acquisition Regulation (FAR) E-Verify clause, and 22 states have enacted laws requiring some or all employers to use the system, according to the National Conference of State Legislatures.
The legal foundation for the program rests on the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA), which authorized the pilot programs that evolved into E-Verify, and subsequent reauthorizations. The program covers only employees hired after an employer's enrollment date — it does not apply retroactively to existing workforces unless specific state law or contract terms require reverification.
How it works
The E-Verify process follows a defined sequence that begins after, not before, an employee's first day of work. Federal rules prohibit pre-employment screening through E-Verify before a job offer is accepted.
- Form I-9 completion — The employer and employee complete Form I-9 no later than the employee's first day of employment, with the employee presenting acceptable identity and work-authorization documents.
- Case creation — The employer enters the employee's I-9 data into the E-Verify system within three business days of the hire date.
- Database query — E-Verify transmits the data to SSA and, where applicable, DHS records, checking fields including name, date of birth, Social Security number, and immigration document numbers.
- Initial result — The system returns one of four initial results: Employment Authorized, SSA Tentative Nonconfirmation (TNC), DHS Tentative Nonconfirmation, or DHS Verification in Process.
- Resolution — If a TNC is issued, the employee has the right to contest it through the relevant agency within eight federal government working days. The employer must continue employing the worker during the referral period.
- Final case closure — The case closes with either Employment Authorized, Final Nonconfirmation, or Close Case and Resubmit status.
E-Verify photo matching applies automatically when an employee presents a U.S. passport, passport card, Permanent Resident Card (Form I-551), or Employment Authorization Document (Form I-766), allowing the employer to compare the document photo against images stored in DHS databases.
Common scenarios
Federal contractor compliance — Employers holding federal contracts with the FAR E-Verify clause (48 C.F.R. § 22.1800) are required to verify all new hires and existing employees assigned to covered contracts. The requirement flows down to qualifying subcontractors.
State-mandated participation — Arizona's Legal Arizona Workers Act (A.R.S. § 23-214) requires all employers in the state to use E-Verify, with penalties including license suspension for violations. Georgia, Mississippi, and Alabama have enacted comparable universal employer mandates.
Tentative Nonconfirmation (TNC) handling — A TNC does not mean the employee is unauthorized to work. SSA TNCs frequently arise from name mismatches, unreported name changes, or data entry errors. Employers who terminate or refuse to continue employing a worker solely on the basis of a TNC, before the contest process concludes, are in violation of E-Verify program rules and may face anti-discrimination liability under the Immigration and Nationality Act (INA) § 274B.
Self-Check function — USCIS offers a separate voluntary tool called myE-Verify that allows individuals to check their own employment eligibility status before entering the job market. This tool does not create an E-Verify case and cannot be used by employers.
Decision boundaries
E-Verify produces distinct outcome states that carry specific employer obligations. The table below contrasts the two most consequential outcomes:
| Outcome | Meaning | Employer obligation |
|---|---|---|
| Employment Authorized | Records match; eligibility confirmed | Close case; retain record |
| Final Nonconfirmation (FNC) | Eligibility could not be confirmed after contest period | Employer may terminate; must close case |
A Final Nonconfirmation does not constitute a finding of unauthorized status by a federal court or immigration judge — it is a database-level mismatch. Employers are not legally required to terminate an employee following an FNC, though continued employment must be reported to USCIS. Failure to report continued employment after an FNC is a program violation.
The distinction between a TNC and an FNC is procedurally critical. A TNC is an interim result that triggers a mandatory referral window; an FNC is a terminal result that closes the referral process. Employers who treat a TNC as an FNC — by immediately terminating employment — expose themselves to anti-discrimination enforcement by the Department of Justice Civil Rights Division, Immigrant and Employee Rights Section (IER).
Employers subject to DHS immigration enforcement policy scrutiny should be aware that E-Verify participation, while reducing liability exposure under IRCA's good-faith defense provisions, does not immunize an employer from I-9 audit penalties if underlying paperwork violations exist independent of the electronic verification outcome.
