Employment eligibility verification is one of the most heavily enforced areas of federal labor law — and one of the most frequently mismanaged. The Form I-9 process, mandated by the Immigration Reform and Control Act of 1986 (IRCA), requires every U.S. employer to verify the identity and work authorization of every employee hired after November 6, 1986.
In 2026, with immigration enforcement at the forefront of federal policy, employers face heightened scrutiny. ICE’s Homeland Security Investigations (HSI) division has significantly increased the volume of I-9 audits — known as Notice of Inspection (NOI) actions — targeting employers across industries.
I-9 Basics: What the Law Requires
Every employer must complete a Form I-9 for each employee within three business days of the employee’s first day of work for pay. The form requires the employer to physically examine original documents that establish both the employee’s identity and their authorization to work in the United States. Employers may not specify which documents an employee must present.
Completed I-9 forms must be retained for the duration of the employee’s employment and for either three years after the date of hire or one year after the date of termination, whichever is later. They must be made available for inspection by ICE, the Department of Labor, or the Office of Special Counsel upon request — typically within three business days of receiving a Notice of Inspection.
The Most Common I-9 Violations
| Violation Type | Description | Penalty Range (Per Violation) |
| Missing I-9 forms | No I-9 completed for an employee | $281 – $2,789 |
| Late completion | I-9 completed after the 3-day deadline | $281 – $2,789 |
| Incomplete sections | Missing signatures, dates, or document info | $281 – $2,789 |
| Improper re-verification | Failure to re-verify expiring work authorization | $281 – $2,789 |
| Knowingly hiring unauthorized workers | Hiring workers not authorized to work in the U.S. | $698 – $27,894 (first offense) |
⚠️ 2026 Enforcement Reality: Federal worksite enforcement actions have increased significantly. A single audit finding multiple violations across a workforce of 50 employees can result in penalties exceeding $100,000. The best time to conduct an internal I-9 audit is before ICE does it for you.
E-Verify: What It Is and When It’s Required
E-Verify is an internet-based system operated by the Department of Homeland Security in partnership with the Social Security Administration. It allows employers to electronically verify the employment eligibility of newly hired employees. E-Verify does not replace the I-9 — it supplements it.
E-Verify participation is mandatory for: all federal contractors and subcontractors; employers in states with mandatory E-Verify laws (currently 22 states); and employers participating in certain federal programs or receiving federal funding.

Conducting a Self-Audit: Where to Start
If your organization has not conducted an internal I-9 audit in the past 12 months, now is the time. A self-audit involves reviewing all current I-9 forms for completeness and accuracy, identifying any missing forms, and correcting technical errors using the proper correction protocol — single line through the error, correct information, initials, and date. Never use correction fluid.
