Just a reminder that a revised I-9 form was released by the USCIS on March 8, 2013. Employers have a 60-day grace period, but will be required to use the new form after May 7, 2013. The main changes to the form include additional data fields, improved instructions, and a revised layout. A copy of the new form is attached, and can also be found here.
A new I-9 does not need to be completed for existing employees who already have an I-9 on file, unless their employment eligibility needs to be re-verified.
The USCIS also issued a revised "Handbook for Employers: Guidance for Completing Form I-9," which provides practical guidance on completing the I-9. The Handbook can be found here.
