The U.S. Citizenship and Immigration Services has revised the Employment Eligibility Verification Form I-9, which all employers are required to complete for each employee hired in the United States. “The revisions to Form I-9 contain formatting changes and the inclusion of additional data fields,” according to the Department of Homeland Security Notice published on March 8, 2013, in the Federal Register. “Employers are required to use the Form I-9 to verify the identity and employment authorization eligibility of their employees.” Employers must use the new version of the form for all new hires and re-verifications, effective immediately. Employers may continue to use previously accepted versions (rev. 02/02/09)N and (rev. 08/07/09)Y until May 7, 2013. After May 7, 2013, employers must only use the new version.
