After December 26, 2007, employers who fail to use the new Form I-9 may be subject to all applicable penalties. All employers are required to complete a Form I-9 for each new employee hired in the United States. The revision removes five documents for proof of both identity and employment eligibility, including: Certificate of U.S. Citizenship (Form N-560 or N-570); Certificate of Naturalization (Form N-550 or N-570); Alien Registration Receipt Card (Form I-151); the unexpired Reentry Permit (Form I-327); and the unexpired Refugee Travel Document (Form I-571). The forms were removed because they lack sufficient features to help deter counterfeiting, tampering, and fraud. Additionally, the most recent version of the Employment Authorization Document (Form I-766) was added to List A of the List of Acceptable Documents on the revised form. The revised list now includes: a U.S. passport (unexpired or expired); a Permanent Resident Card (Form I-551); an unexpired foreign passport with a temporary I-551 stamp; an unexpired Employment Authorization Document that contains a photograph (Form I-766, I-688, I-688A, or I-688B); and an unexpired foreign passport with an unexpired Arrival-Departure Record (Form I-94) for nonimmigrant aliens authorized to work for a specific employer. Employers are advised to begin using the new Form I-9 (Rev. 06/05/07), immediately, and this version will be mandatory upon publication in the federal register.
