Why Your HCM Auto-Fills Form I-9 Section 1 — and Why That's Now a Substantive Violation Problem
Read the article
If an employee comes to you with a renewed work permit, what do you do? If your answer is "redo the I-9 from scratch," you've already made the most common reverification mistake we see in audit prep. Reverification is one of the most misunderstood parts of Form I-9 compliance — and the mistakes are almost always the same three.
HR teams who have run I-9s for years still get tripped up here. The trigger isn't what you'd expect, the document doesn't drive the timing, and the form you're supposed to use isn't a new I-9. Each of these three errors creates a substantive violation under ICE's current enforcement framework — the kind that doesn't get a 10-day cure window when an inspection arrives.
Reverification is never required for US citizens or noncitizen nationals. Their employment authorization does not expire, full stop. The M-274 is unambiguous — and yet this is one of the most common mistakes HR teams make.
Where it goes wrong: an employee comes back with a renewed driver's license, gets married and updates their name, or mentions their US passport expired. A well-meaning HR coordinator sees an old expiration date and decides to "update" the I-9 — sometimes via Supplement B, sometimes via a brand-new I-9. Either way, wrong.
The rule, per USCIS: employers must not reverify US citizens, noncitizen nationals, lawful permanent residents who presented a Form I-551 (Permanent Resident Card), or any List B (identity) document. List B expirations are never a reverification trigger.
What happens if you reverify a citizen anyway: you've requested more or different documents than the law requires. Under INA Section 274B, that's an unfair documentary practice — sometimes called "document abuse" or over-documentation. The Department of Justice's Immigrant and Employee Rights Section (IER) investigates these claims, with penalties including civil fines, back pay, and court orders to reinstate the affected employee. Over-documentation is one of the most reliable ways to turn a well-intentioned compliance effort into a discrimination charge.
What to do instead: if a US citizen's identity document expires or their name changes, do nothing — or note it on Supplement B as a recordkeeping option. Don't collect new documents. Same for an LPR whose green card expired: their status hasn't expired, only the card.
The trigger for reverification is the employment authorization expiration date in Section 1 — not the document expiration date in Section 2. Most HR teams have this backwards. They watch document dates because that's what shows up in their HRIS. The form itself tells you to look elsewhere first.
Per the M-274, employers must check both: review Section 1 for the date employment authorization expires, and Section 2 for the date the document expires. The two may not match. Reverify by the earlier of the two dates.
This matters because of what employees attest to in Section 1. There are four citizenship/status categories on the current Form I-9:
Where teams get it wrong: an employee in box 4 ("noncitizen authorized to work") presents an Employment Authorization Document (EAD) in Section 2. HR diaries the document expiration, never looks at Section 1, and reverifies on the wrong date. For visa transitions — OPT to H-1B, H-1B to green card, asylum to LPR — see our guide on I-9 reverification when visa status changes.
What happens if you miss the date: a late reverification is a substantive violation. Under ICE's redefined substantive violation framework, late reverifications no longer get the 10-day cure window that procedural errors get — they're scored as full violations during a Notice of Inspection.
What to do instead: look at Section 1 first. Compare it to Section 2. Use the earlier date as your trigger, send the employee a 90-day reminder (USCIS recommends this), and complete Supplement B before the date passes.
Most teams don't know they have a reverification problem until ICE shows up. Run your active I-9s through our I-9 risk calculator for a quick exposure estimate, or book a free compliance call to walk through your reverification workflow before it becomes an audit finding.
Reverification is recorded on Supplement B — a separate page that attaches to the original Form I-9. You do not complete a new I-9 from scratch. Supplement B is the current name for what used to be Section 3 on the pre-2023 form. The rule is the same: reverification continues the original record, it does not replace it.
Where teams get it wrong: the employee comes back with a renewed EAD, HR pulls a blank I-9, has the employee re-attest in Section 1, completes Section 2 with the new document, and files it. Now there are two I-9s — and the new one shows a hire date that's actually a reverification date. One of the most common substantive findings we see in client audits.
"When we run a self-audit for a new client, the reverification errors are almost always the same three patterns," says Patricia Duarte, Director of Compliance at i9 Intelligence. "Someone reverified a US citizen because a driver's license expired, someone reverified an LPR because the green card expired, or someone did a brand-new I-9 instead of using Supplement B. The third one is everywhere — especially after an HRIS migration where the original I-9 went missing."
The rule, per USCIS: when employment authorization or documentation expires, the employer completes Supplement B and attaches it to the previously completed I-9. The employee presents an unexpired List A or List C document (or an acceptable receipt). The employer records the document title, number, and expiration date, then signs and dates Supplement B.
What happens if you complete a new I-9 instead: you've replaced a valid form with one that misrepresents the hire date and breaks the audit trail. ICE inspectors look for exactly this pattern — a "new" I-9 with a hire date years after the actual hire is a red flag, and a missing original is itself a substantive violation.
What to do instead: pull the original I-9, attach Supplement B, complete it, and file the two together. If your original is the pre-2023 version (with the former Section 3 on the form itself), USCIS allows you to use Supplement B from the current form and attach it — no need to redo the original.
Two things, in order. First, run a self-audit to find which I-9s have reverification errors — our 2026 self-audit playbook walks through the process.
Second, correct the errors using the proper protocol. Don't backdate. Don't shred the bad I-9. Use single-line strikethrough with initials and date for cell-level errors, attached memos for missing entries, and a fresh Supplement B (attached, not replacing) when a brand-new I-9 was completed in error. Our guide to fixing I-9 mistakes covers each scenario.
If the wrong-form mistake is widespread — for example, an HRIS migration that generated fresh I-9s for every reverification — get a second set of eyes before correcting. Mass corrections done wrong compound the problem.
Reverification updates Form I-9 (via Supplement B) when existing authorization expires and the employee remains authorized. Re-establishing happens when authorization actually lapsed — that usually requires a new I-9, because employment was effectively interrupted. Most HR scenarios are reverification.
It depends on what the employee originally attested to in Section 1. If they were a "noncitizen authorized to work" with a Section 1 expiration date and later become a lawful permanent resident, the cleanest path is a new Form I-9 with the new attestation — Section 1 status is changing, not just the documents. The visa-status guide above covers this scenario.
The I-94 establishes the period of authorized stay. If the employee presented an I-94 (or foreign passport with I-94) for Section 2, reverify before that expiration date with an unexpired List A or List C document. A renewed visa stamp is not a new I-94 — check the new admission record's expiration.
No. Reverification goes on Supplement B, attached to the original. A new I-9 instead breaks the audit trail and is one of the most common substantive findings we see. The only exception: when an employee's identity has substantially changed and cannot be linked to the previous identity, USCIS directs employers to complete a new I-9 and attach it to the previous one. That's not routine reverification.
Before the expiration date — not on it, not after. Supplement B must be signed before the Section 1 expiration date (or the Section 2 document date, whichever is earlier). A Supplement B completed even one day late is a substantive violation.
If any of this raised a "wait, did we do that right?" question, that's the right instinct. We help HR teams clean up reverification errors every week — usually before they become audit findings, sometimes during a live inspection.
