Reverification and rehires: when you need Supplement B

The mistake to avoid first

An expired green card does not mean expired work authorization. Lawful permanent residents never need reverification, even when the physical card expires. Reverifying them anyway isn't just unnecessary — it can be treated as discriminatory. (Related: why a Permanent Resident card doesn't require an expiration date in E-Verify.) If you remember one thing from this article, make it this one.

Who needs reverification

Only employees whose work authorization itself expires — typically those who attested as "alien authorized to work" with an expiration date in Section 1, or who presented time-limited employment authorization documents.

Never reverify: U.S. citizens, noncitizen nationals, or lawful permanent residents.

When and how

Reverify on or before the day the current authorization expires — the employee cannot keep working on expired authorization. Track the dates from Section 1/Section 2 and start early enough for the employee to obtain renewal documents; in Onboarded, expiration-driven tasks surface this ahead of the deadline.

Record the reverification on Supplement B (this replaced the old Section 3). The employee chooses which acceptable document to present — the employer can't demand a specific one, same rule as the original I-9. Note that receipts have limited validity in reverification situations.

Rehires

When someone returns:

• Rehired within 3 years of the original I-9: you can either complete Supplement B on the original I-9 or do a fresh I-9 — your choice, applied consistently.

• Rehired after more than 3 years: a new I-9 is required.

In Onboarded, a rehire flow reopens onboarding for the returning employee; whether that generates a new I-9 or references the prior record depends on your configuration — ask support if you're unsure which your org uses.

Name changes

A legal name change doesn't require a new I-9 or reverification. Noting it on Supplement B is recommended, not mandatory.

E-Verify and reverification

Do not create a new E-Verify case for a reverification. E-Verify is for new hires (and specific federal contractor situations) — running existing employees through it outside those rules violates the MOU.

Regulations change. Verify current guidance at USCIS I-9 Central. This article is general guidance, not legal advice.
