E-Verify Compliance
E-Verify is a federal web-based employment eligibility verification system operated by the U.S. Department of Homeland Security (DHS) in partnership with the Social Security Administration (SSA). This page covers how the system works, which employers must use it, the process steps involved, and the boundaries between mandatory and voluntary participation. Understanding E-Verify obligations is essential for employers navigating the broader framework of I-9 employment eligibility compliance and federal hiring law.
Definition and scope
E-Verify supplements — but does not replace — the Form I-9 process. Employers compare information from a new hire's Form I-9 against DHS and SSA databases to confirm employment authorization. The program was established under the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA, Pub. L. 104-208) and operates under the authority of 8 U.S.C. § 1324a.
Mandatory participation is not universal at the federal level. Federal contractors and subcontractors holding contracts with a Federal Acquisition Regulation (FAR) E-Verify clause are required to use the system (FAR 22.1800–22.1803). Outside federal contracting, state law drives most mandatory enrollment. As of 2024, 23 states have enacted laws requiring E-Verify use for some or all private employers (NCSL, State E-Verify Laws). Voluntary participation is open to any employer in the United States.
Program enrollment and case submission occur through the DHS-operated portal at E-Verify.gov, administered by the U.S. Citizenship and Immigration Services (USCIS) within DHS.
How it works
The E-Verify process follows a defined sequence tied to the Form I-9 timeline. Each step has regulatory constraints that determine when a case must be initiated and how long a response is valid.
- Employer enrollment — Employers register at E-Verify.gov, designating program administrators and agreeing to a Memorandum of Understanding (MOU) with DHS and SSA. Each employer site location requires its own enrollment record.
- Form I-9 completion — The new hire completes Section 1 of Form I-9 on or before the first day of paid work.
- Case creation — The employer enters the employee's I-9 data into E-Verify no later than 3 business days after the hire's first day of employment. Cases created before an offer is accepted violate program rules.
- Initial automated response — The system returns one of four results: Employment Authorized, Tentative Nonconfirmation (TNC), Case in Continuance, or DHS/SSA Referral.
- Tentative Nonconfirmation handling — If a TNC is issued, the employer must notify the employee in private within the same business day. The employee then has 10 federal government working days to contest the result by contacting the relevant agency (DHS or SSA).
- Final case closure — Cases resolve as Employment Authorized, Final Nonconfirmation, or an employee-initiated No Action closure if the employee chooses not to contest.
Employers may not take adverse action — including delaying a start date or terminating employment — based solely on a TNC result while the contest period is active. This prohibition is stated directly in the E-Verify MOU and the program's User Manual (USCIS E-Verify User Manual).
Common scenarios
Federal contractors must verify all new hires and, in some cases, existing employees assigned to covered contracts. The FAR clause at 52.222-54 specifies that contractors with contracts of more than $150,000 and a period of performance longer than 120 days are subject to the requirement (FAR 52.222-54).
State-mandate employers face requirements that vary by sector and employer size. Arizona, for example, requires E-Verify use for all employers under the Legal Arizona Workers Act. Georgia mandates enrollment on a phased basis tied to employer headcount, starting with employers of 500 or more employees in 2012 and descending to employers of 11 or more by 2013 (Georgia O.C.G.A. § 13-10-91).
Voluntary participants must still follow all program rules — including the prohibition on pre-employment screening (creating a case before the hire date) and selective verification (running only certain demographic groups through E-Verify, which violates anti-discrimination provisions under 8 U.S.C. § 1324b).
Employers operating across state lines should consult multi-state employer compliance resources, since conflicting state mandates can create procedural inconsistencies.
Decision boundaries
The central distinction in E-Verify compliance is mandatory versus voluntary participation, which determines enforcement exposure and penalty framework.
| Factor | Federal Contractor | State-Mandated Employer | Voluntary Employer |
|---|---|---|---|
| Legal basis | FAR 22.1800 | State statute | Program MOU only |
| Covered workers | New hires + assigned employees | Typically new hires | New hires only |
| Noncompliance risk | Contract termination, suspension | State civil penalties, license suspension | MOU termination |
| Anti-discrimination rules | Apply | Apply | Apply |
Anti-discrimination protections under the Immigration and Nationality Act (INA) apply across all three categories. The Department of Justice Civil Rights Division's Immigrant and Employee Rights Section (IER) enforces these provisions. Employers found to have used E-Verify in a discriminatory pattern face potential civil money penalties under 8 U.S.C. § 1324b (DOJ IER).
E-Verify compliance intersects directly with workplace compliance penalties exposure when employers fail to initiate cases within the required 3-business-day window or take adverse action during a TNC contest. Recordkeeping requirements for closed E-Verify cases align with, but are separate from, Form I-9 retention obligations under compliance recordkeeping requirements.
