Form I-9 Reverification: What Is It and Who Needs It for Compliance?

HR professionals already have enough on their plates, from recruiting and onboarding to benefits administration and compliance management. One task that often gets overlooked until it becomes urgent is Form I-9 reverification. Though only a few reverifications might be required per year, failing to properly complete reverification can lead to fines, and even legal trouble.

Top Takeaways for HR

• While failing to reverify temporary visas creates massive liability, reverifying individuals who hold permanent authorization is equally illegal. HR must ensure that recruiters and managers never request updated paperwork for U.S. passports, valid Green Cards, or standard List B identity documents (like driver's licenses) when they expire
• Waiting until 30 or 60 days before a temporary visa expires to alert an employee is an operational failure that can lead to immediate business disruptions. A compliant strategy requires an automated tracking framework that initiates the first notification 120 days out.

What Is Form I-9 Reverification & Why Does It Matter?

Form I-9 is the official federal document used to verify the identity and employment eligibility of anyone hired in the United States as a W-2 employee. All employers, regardless of size or industry, must complete a Form I-9 for every employee hired after November 6, 1986.

But here’s the catch: not all employment authorization documents are permanent. That’s where Form I-9 reverification comes in. Form I-9 reverification is the process of updating Supplement B (formerly known as Section 3) of Form I-9 when an employee’s temporary work authorization is approaching expiration. Employers are responsible for ensuring employment eligibility remains valid throughout the employee’s tenure, and there cannot be any lapse in employment eligibility.

Why does this matter? Because failing to properly manage reverifications can result in:

• Costly fines and penalties
• Increased audit exposure
• Compliance violations under the Immigration Reform and Control Act (IRCA)
• Business disruptions if employment authorization lapses

Even if your organization only handles a handful of reverifications each year, missing deadlines or completing them incorrectly can create significant risk. Form I-9 reverification confirms updated I-9 documentation which is required during internal audits or ICE inspections.

HR Pro Tip: You should conduct periodic audits to verify that your reverification tracking system is working properly. Don’t delay, start now.

What Is I-9 Reverification?

Simply put, Form I-9 reverification is the process of revalidating an employee’s authorization to work in the United States before their current work authorization expires. This process is completed using Supplement B of the original Form I-9.

It’s also important for HR teams to distinguish between reverification and rehiring:

• Reverification - Applies to current employees whose temporary work authorization is expiring.
• Rehiring - Occurs when a previously terminated employee returns to the organization within three years of the date the Form I-9 was completed. While employers may update the original Form I-9, many organizations choose to complete a new form altogether because tracking prior hire dates can become difficult over time.

The legal framework for reverification falls under IRCA and is enforced by the U.S. Department of Homeland Security (DHS).

Who Needs to Be Reverified?

Not every employee requires Form I-9 reverification. Typically, reverification applies to employees with temporary employment authorization who fall into one of the following categories:

Aliens with Temporary Work Visas

Aliens’ work authorization is tied directly to the validity of their visa. This includes individuals working under temporary visa classifications such as:

• H-1B
• L-1
• Other nonimmigrant work-authorized visa categories

Employees with Form I-766 Employment Authorization Documents (EADs)

Employees with EADs may require reverification when their documents expire, including individuals under:

• DACA
• Temporary Protected Status (TPS)
• Asylum status
• F-1 student employment authorization

If you have employees from counties with Temporary Protected Status, learn what you can do to monitor and handle any changes in status. 

Lawful Permanent Residents Presenting Temporary Evidence

Certain lawful permanent residents who present temporary evidence of permanent residency status may require reverification.

Examples include:

• Temporary I-551 stamps (ADIT stamps)
• Machine Readable Immigrant Visas (MRIVs)

Additionally, individuals presenting Form I-751 alongside an expired Form I-551 may require reverification based on current USCIS guidance and extension timelines.

Who Doesn’t Require Reverification

On the flip side, you should NOT reverify:

• U.S. citizens
• Lawful permanent residents with valid green cards
• Employees with permanent work authorization

This includes situations where documents like passports or permanent resident cards expire. Expired documents alone do not automatically trigger reverification requirements.

Improperly reverifying employees who do not require it can raise compliance concerns during an audit.

When Does Reverification Need to Happen?

Timing is critical when it comes to Form I-9 reverification. Reverification must be completed no later than the expiration date of the employee’s current work authorization. Allowing employment authorization to lapse could place the organization in violation of federal law because the employee could then be working without legal authorization to do so.

To stay ahead of deadlines, HR teams should implement proactive tracking and notification systems.

Recommended Reverification Reminder Timeline

Best practice is to send automated reminders to:

• The employee
• The employee’s manager
• The HR team responsible for processing reverifications

Recommended notification intervals include:

• 120 days before expiration
• 90 days before expiration
• 60 days before expiration
• 30 days before expiration

These reminders help create an audit trail showing the company acted in good faith and provided sufficient time for document renewal.

HR IRL: An HR manager discovers during an internal audit that an employee’s EAD expired two weeks earlier. Because no automated reminders were in place, the organization now faces potential compliance exposure and must immediately investigate employment authorization status.

Using the proactive steps listed above could have alleviated this potentially risky situation.

How to Complete a Form I-9 Reverification

While the process itself is straightforward, accuracy matters. Here’s a step-by-step breakdown you and your HR teams can follow.

Step 1: Employee Presents Updated Documentation

The employee must provide original, unexpired documentation to establish continued work authorization.

Step 2: Complete Supplement B

The employer representative completes Supplement B of the original Form I-9.

Step 3: Record the New Document Information

The employer enters the updated document information into Supplement B.

Acceptable reverification documents include:

• List A documents
• List C documents

List B documents, such as driver’s licenses, cannot be used for reverification because identity was already established during the original verification process.

Step 4: Sign and Date Supplement B

The employer representative must sign and date the reverification section.

Step 5: Retain the Updated Form Properly

Employers must securely retain the updated form, whether electronically or physically, in accordance with DHS retention requirements.

Don’t forget to provide the employee with advance notice to allow time to present updated documentation. A lack of cooperation on the employee’s part should be documented, and the company may need to consider termination if work authorization can’t be verified by the deadline.

Common Form I-9 Reverification Mistakes to Avoid

Even experienced HR professionals can run into issues with reverification. Here are some of the most common mistakes:

• Reverifying U.S. Citizens. - This is unnecessary and should never occur.
• Accepting Incorrect Documents - Only List A or List C documents are acceptable for reverification.
• Completing Section 1 Again - HR should complete Supplement B only and not restart the entire form unnecessarily.
• Missing Signatures or Dates - Supplement B must always be signed and dated upon completion.
• Poor Recordkeeping - Disorganized documentation can quickly become a liability during an ICE inspection or internal audit.

Best Practices for HR Teams

Managing reverifications becomes much easier when organizations build repeatable, scalable processes. Here are some tips:

• Use a reverification tracker: A simple Excel or Google sheet, calendar tool, or integrated HRIS system can keep you ahead of deadlines.
• Assign a point person: Having one person responsible for I-9 management helps ensure consistency and accountability.
• Stay organized: Maintain clearly labeled, easily accessible (but secure) documentation that’s audit-ready at any time.
• Conduct regular internal audits: Spot check your Form I-9s quarterly or bi-annually to catch errors before they become problems.
• Stay current on regulatory changes: Employment authorization guidance can change. You should regularly monitor updates from DHS and USCIC.
• Consider partnering with experts: HR CaaS partners can help support your reverification tracking, audit readiness, document management, and policy updates, which reduces the administrative burden on you and your HR teams.

What Form I-9 Reverification Means for Your Organization

Form I-9 reverification may only affect a portion of your workforce, but the compliance risks associated with mishandling it can be significant.

As organizations move through the year and focus on optimizing processes, operations, and audit readiness, now is the time for HR leaders to evaluate whether their reverification process is proactive, organized, and scalable.

Small improvements can make a major difference, including:

• Automating reminders
• Standardizing documentation practices
• Conducting internal audits
• Training HR staff on reverification procedures
• Partnering with compliance experts when needed

Don’t let reverification slip through the cracks, treat it as a vital piece of your overall compliance strategy. At the end of the day, a well-managed reverification process protects both your company and your employees while strengthening your company’s compliance strategy.
