USCIS Reminds all U.S. Employers of Requirements to Use Revised Form I-9, Employment Eligibility Verification

WASHINGTON, April 3, 2009 — U.S. Citizenship and Immigration Services (USCIS) issued a reminder that the revised Form I-9, Employment Eligibility Verification (Rev. 02/02/09), goes into effect today for all U.S. employers. The revision date is printed on the lower right-hand corner of the form.

The interim final rule, published Dec.17, 2008 in the Federal Register, revised the list of documents acceptable for the Employment Eligibility Verification (Form I-9) process. Employers may no longer use previous versions of the Form I-9.

The revised list improves the security and effectiveness of the Form I-9 process. The list specifies that expired documents are no longer acceptable forms of identification or employment authorization. Allowing for expired documents makes it more difficult for employers to verify an employee’s identity and employment authorization and compromises the Form I-9 process.

USCIS also updated the Handbook for Employers – Instructions for Completing Form I-9 to reflect the requirements of the revised Form I-9.

Employers who do not have computer access can order Forms I-9 by calling our toll-free forms line at 1-800-870-3676.
