U.S. Citizenship and Immigration Services (USCIS) will require US employers to use its revised Employment Eligibility Verification Form I-9 beginning on May 7, 2013. 

All employers are required to complete a Form I-9 for each employee hired in the United States.  The updated form includes new information fields.  In addition, the USCIS has stated it also has new formatting to reduce errors and clearer instructions for both employees and employers.

Employers may continue to use previously approved versions until May 7, 2013.  After that date, they are required to only use the Form I-9 with a revision date of. 03/08/13.  These revision dates are printed on the lower left corner of the form.  Employers are not required to complete the new Form I-9 for current employees if they have a properly completed form on file already.

A Spanish-language version of the new form is also available on the USCIS website for use in Puerto Rico only.  Spanish-speaking employers and employees in the 50 states, Washington, D.C., and other U.S. territories can refer to the Spanish version but must complete the English-language version of the form.

The new Form I-9 is available in English and Spanish online at http://www.uscis.gov.
