U.S. Citizenship and Immigration Services (USCIS) has changed the revision date on its Form I-9. Previously, the revision date (which appears in the form's bottom right hand corner) appeared as "Rev. 02/02/09." Earlier editions of the I-9 form were deemed not acceptable. This month USCIS amended the I-9 form to reflect a new revision date of "Rev. 08/07/09." Employers may use the Form I-9 with the revision date of either 02/02/09 or 08/07/09. Other than the form revision date, the two forms are essentially identical.
