When Is I-9 Reverification Required?

A lot of I-9 mistakes happen after the employee is already on payroll. Initial verification gets attention. Reverification often gets missed, rushed, or done incorrectly. If you are asking when is I-9 reverification required, the short answer is this: it is required when an employee’s temporary employment authorization or employment authorization documentation has expired, but not in every case where an ID or document reaches its expiration date.

That distinction matters. Employers that reverify too late can create compliance exposure. Employers that reverify the wrong employees or ask for the wrong documents can create discrimination problems. For HR teams, remote employers, and companies using an authorized representative to complete Form I-9 functions, this is one of the areas where being precise matters more than being fast.

When is I-9 reverification required

I-9 reverification is required when the employee presented temporary proof of work authorization that has an expiration date, and that authorization is now expiring or has expired. In most cases, the employer handles this in Supplement B of Form I-9, which replaced the old Section 3 process on newer versions of the form.

The practical question is not whether a document expired. The practical question is whether the employee’s employment authorization requires reverification. Some expired documents trigger action. Others do not.

For example, if an employee originally presented an Employment Authorization Document, often called an EAD, with an expiration date, the employer generally must reverify by the date that work authorization expires unless an automatic extension or other valid rule applies. If the employee is work-authorized permanently and presented a Permanent Resident Card, reverification is not required just because the card later expires.

That is where employers commonly get tripped up. They see an expiration date and assume they need to update the file. That is not always correct.

Situations that usually require reverification

Reverification generally applies when the employee’s authorization to work in the United States is temporary. This can include certain noncitizens who presented time-limited employment authorization documents or work authorization connected to a specific immigration status.

If the employee gave a document from List A or List C showing temporary employment authorization, the employer must monitor the expiration and complete reverification on time. The employee must then present an acceptable unexpired document showing continued authorization to work.

A few common examples include an expiring EAD, certain I-94 records showing temporary work-authorized status, or other acceptable documentation tied to temporary employment authorization. The exact document combination matters, and so does whether a status has been extended automatically under a specific rule. This is one reason employers should avoid guessing from memory.

Situations that do not require reverification

Not every expired document creates an I-9 task. Reverification is not required for US citizens and noncitizen nationals. It is also not required for lawful permanent residents who presented a Form I-551, even when that card later expires.

Likewise, employers do not reverify identity documents from List B. A driver’s license can expire without creating a reverification requirement. The same rule applies to many identity documents used only to establish identity at the initial hire stage.

This is a key compliance point. If an employer asks a worker to present a new driver’s license or an unexpired green card solely because the card expiration date passed, that request can be improper. Employers should reverify employment authorization when the rules require it, not reverify identity or citizenship status unnecessarily.

What document can the employee present at reverification

At reverification, the employee may choose which acceptable unexpired document to present from either List A or List C, as long as it shows continuing employment authorization. The employer cannot demand a specific document.

That means if the employee previously used one type of work authorization document, the employer cannot insist on seeing that same document again. The employee gets to choose from the acceptable options. This is one of the most common Form I-9 errors in real-world onboarding and re-onboarding.

For HR teams, the safer approach is simple: notify the employee that reverification is required, provide the lawful deadline, and allow the employee to present any acceptable unexpired documentation that satisfies the Form I-9 rules.

Timing matters more than most employers realize

Reverification should be completed no later than the date the employee’s work authorization expires. Waiting until well after the expiration date is a problem. Completing it too early can also create avoidable issues if the process becomes inconsistent across employees.

A practical internal process is to track upcoming expiration dates in advance and begin outreach before the deadline. Many employers use a 90-day and 30-day reminder system. That gives the employee time to gather updated documentation while allowing HR to stay on schedule.

The employer should not continue employing a person after temporary work authorization has expired unless the employee has presented acceptable proof of continued authorization or a valid automatic extension applies. That is where recordkeeping and timing meet actual compliance risk.

Rehires are related, but not the same thing

Some employers confuse reverification with rehiring. They overlap, but they are not identical.

If you rehire an employee within the allowed period under the Form I-9 rules, you may be able to complete Supplement B rather than preparing a completely new Form I-9. But if the employee’s work authorization has expired, reverification is still part of that review. If the employee remains authorized and the original form is still valid for rehire purposes, the employer may only need to update the rehire information.

This is one of those it-depends areas. The right step depends on the age of the original I-9, the version of the form used, whether the employee was rehired within the permitted timeframe, and whether the employee’s work authorization remained valid.

Remote hiring adds another layer

For remote employers, reverification can be operationally harder even when the rule itself is straightforward. Someone still has to examine the employee’s document and complete the employer section correctly. If your company uses an authorized representative for I-9 completion, the same care is needed for any follow-up work tied to Form I-9 obligations.

That matters in California, where employers should understand that notaries are not automatically authorized to perform I-9 work simply because they are notaries. The employer appoints an authorized representative for the I-9 function, and that person must follow the form instructions accurately. In practice, many businesses prefer a provider that focuses specifically on I-9 document examination rather than treating it like a side task.

For Southern California employers with distributed workers, Afridi Immigration and Legal Services provides appointment-based authorized representative support for Form I-9 procedures, with mobile service across multiple counties. That kind of specialized support can help reduce preventable clerical errors, although employers remain responsible for compliance.

Common reverification mistakes

Most reverification mistakes are not complicated. They happen because teams use shortcuts.

One common error is reverifying permanent residents when a green card expires. Another is asking for a specific document instead of allowing employee choice. A third is failing to track expiration dates at all, then discovering the issue after the deadline has passed.

There is also the opposite problem: over-documenting. Some employers photocopy extra records, request unnecessary updates, or reverify categories of employees who should not be reverified. That can create consistency problems and, in some cases, raise unfair employment practice concerns.

The best internal standard is to apply the same process every time. Check what document established work authorization, confirm whether that authorization was temporary, verify whether any extension rule applies, and complete the correct section of the current form properly.

A practical way to stay compliant

If your organization handles frequent onboarding, remote hires, or employees with temporary work authorization, reverification should not be left to memory or email inbox searches. It should be part of a calendar-based compliance process with clear ownership.

That usually means maintaining accurate I-9 records, reviewing expiring authorization in advance, training whoever completes the employer portion of the form, and using a qualified authorized representative when the employee is not physically present at your office. It also means recognizing the limit of administrative support. Completing forms correctly is not the same as giving legal advice about immigration status.

When there is uncertainty about a worker’s underlying status, automatic extension eligibility, or a complex rehire scenario, legal review may be appropriate. When the task is document examination and compliant completion of the employer side of the form, careful administrative execution is usually what keeps the process on track.

The safest mindset is simple: do not reverify because a document looks old, and do not skip reverification when temporary work authorization actually expires. Get the distinction right, document it correctly, and handle it before it becomes a payroll-day problem.
