Common confusion points

Can I ask the employee which documents to present?

Employers sometimes think they can direct document choice, but the law prohibits it.

Verify that you allow the employee to choose any acceptable document from the list.

Do I need to keep the Lists of Acceptable Documents with the form?

Some think all paperwork must be retained, but the source says it’s not required.

Confirm that only the completed Form I‑9 is retained.

When must Section 2 be completed for a three‑day hire?

The rule changes for hires under three days, causing confusion.

Ensure Section 2 is completed on the first day for hires under three business days.

Am I allowed to request the employee’s A‑Number or I‑94?

Employers may mistakenly request these prohibited items.

Check that you have not asked for USCIS Number, Form I‑94, or foreign passport number.

Do I need to mail the Form I‑9 to USCIS?

The address is listed on the form, leading to the assumption it should be mailed.

Verify that the form must not be mailed to USCIS or ICE.

What if the employee’s documents expire soon?

Employers think they must reject soon‑to‑expire docs, but the source says not to reject due to future expiration.

Confirm you accept documents even if they will expire after the hire date.
