The U.S. Citizenship and Immigration Services (USCIS) has confirmed that the effective date for mandatory use of the new Form I-9 (Form I-9 (Rev. 03/08/13)N) is May 7, 2013. The USCIS’ announcement resolves apparent discrepancies in previously issued guidance that led some employers to question if the effective date for implementing the new Form I-9 was May 7, 2013 or May 8, 2013. The corrected guidance was issued in the Federal Register on April 9, 2013.
