Reverification is the part of Form I-9 that comes back. When an employee’s permission to work has an end date, the employer must confirm continued permission on or before that date.
Miss the date and the employer either keeps someone on payroll without a current record, or suspends a worker who is still authorized. A calendar avoids both.
What needs reverifying
Reverify when the employee’s work authorization expires. In practice that usually means:
- An Employment Authorization Document (EAD) that has an expiration date.
- A foreign passport with Form I-94 showing a status that ends on a set date.
- A List C document from DHS that shows an end date.
Use Supplement B of Form I-9 to record the new document. The employee chooses which acceptable document to present. Do not ask for a specific one.
What never needs reverifying
- U.S. citizens and noncitizen nationals.
- Lawful permanent residents who presented a green card, even if the card itself has expired.
- List B identity documents, such as a driver’s license.
Reverifying these employees is a common error, and asking for more or different documents than the law requires can be treated as discrimination.
A calendar that works
- Record each expiration date in your HR system when Section 2 is completed.
- Send the employee a notice at 90 days and again at 30 days.
- Complete Supplement B before the date, not on the first day after it.
- Keep the reverification with the original Form I-9.
Rules on automatic extensions of EADs have changed more than once. Before treating an expired card as extended, check the current rule on I-9 Central or ask us.
