USCIS’s revised edition of the I-9 employment eligibility verification form, dated 11/14/16, will become mandatory for employers on January 22, 2017. Until that date, employers may continue to use the version dated 03/08/13.

The new edition, which was released in November, does not change the key substantive questions on Form I-9 or the list of acceptable identity and work authorization documents, but it contains some format changes that are intended to reduce completion errors when the form is filled out on a computer.
