Beginning Jan. 22, 2017, employers must use the 11/14/2016 N version of Form I-9, Employment Eligibility Verification, to verify the identity and work eligibility of every new employee hired after Nov. 6, 1986, or for the re-verification of expiring employment authorization of current employees (if applicable).
The date on the form is found on the lower left hand corner of the form. Prior versions of the form will no longer be valid for use. Employers who fail to use Form I-9 11/14/2016 N on or after Jan. 22, 2017 may be subject to all applicable penalties under section 274A of the Immigration and Nationality Act, 8 U.S.C. 1324a, as enforced by U.S. Immigration and Customs Enforcement (ICE).
Employers should continue to follow existing storage and retention rules for each previously completed Form I-9.
USCIS has a good resource called “I-9 Central” at USCIS.GOV for more information.
