6.1 Reverifying Employment Authorization for Current Employees
You must reverify an employee’s employment authorization no later than the date employment authorization expires. The employee must present a document that shows current employment authorization, such as any documentation from List A or C, including an unrestricted Social Security card. You must reject a restricted Social Security card and ask the employee to provide a diﬀerent document from List A or C. You can also accept certain receipts for reverification; see the Acceptable Receipts table in Section 4.4, Acceptable Receipts, for more information. You cannot continue employing a person who does not provide proof of current employment authorization.
When you must reverify an employee, you will complete one block of Supplement B, Reverification and Rehire (formerly Section 3) and attach it to the employee’s original Form I-9. You may use additional blocks on this supplement for subsequent reverifications or updates, attaching additional supplement sheets as needed. If the employee’s previous update or reverification was completed on a Form I-9 version that is no longer valid, you must also complete Supplement B, Reverification and Rehire and attach it to the employee’s original Form I-9. Please check uscis.gov/i-9 for the current Form I-9.
To reverify your employee using Supplement B, Reverification and Rehire:
- Enter the employee’s full name from the original Form I-9 at the top of the supplement.
- If the employee’s name has changed, enter the new name in the appropriate New Name fields in one block of the supplement. Enter only the part of the name that has changed. For example, for employees who changed only their last name, enter the last name in the Last Name field and leave the First Name and Middle initial fields blank.
- Enter the document title, number and expiration date in that block of the supplement.
- You must sign, date and enter your name in the appropriate fields in that block. Keep this supplement page with the original Form I-9.
Some employees may have entered N/A in the expiration date field in Section 1 if they are noncitizens whose employment authorization does not expire, such as asylees, refugees, or certain citizens of the Federated State of Micronesia, the Republic of the Marshall Islands, or Palau. Reverification does not apply for such individuals unless they choose to present evidence of employment authorization in Section 2 that contains an expiration date and requires reverification, such as Form I-766, Employment Authorization Document. Employees with expiring immigration status, employment authorization, or employment authorization documents should have the necessary application or petition filed well in advance to ensure they maintain continuous employment authorization and/or valid documents. USCIS provides employment authorization extensions under certain conditions. See Section 7.0, Evidence of Employment Authorization for Certain Categories, for more information.
