Section 2 within three business days of the hire. ## The rule USCIS says the employee must complete and sign Section 1 of Form I-9 no later than the first day of employment, and may complete it any time after accepting the job. The employer may review documents and complete Section 2 any time from the acceptance of the offer and the completion of Section 1 until three business days after the hire. The employer must make the instructions and the Lists of Acceptable Documents available. ## What employers must do Check that Section 1 is complete and signed. If you participate in E-Verify, the employee must provide a Social Security number. If you do not, the Social Security number is optional. Watch the employment-authorization expiration date. Reverification uses the earlier of the Section 1 date and the List A or List C document date. This review did not confirm which employers must use E-Verify. ## Effective dates The USCIS page was last reviewed September 11, 2026. No January 1, 2027 change to these deadlines was on that page. ## What this means for BOSS partners and associates BOSS is often the employer of record for the associate. Wage, break, leave, posting, and tax rules usually follow the state where the associate works. Tell BOSS that state before the assignment starts. Associates should record every hour worked on the timesheet. Do not promise a pay practice, a leave bank, or a posting the statute does not require. Questions?
