U.S. Citizenship and Immigration Services (USCIS) requires that all employers have their new employees fill out a Form I-9. A new version of the I-9 has been issued by the government, of which the most obvious change is the addition of a second page. If employers do not use the new version of the form after May 7, 2013, they will be considered as non-compliant and will be exposing themselves to the possibility of civil, or even criminal, penalties. Current employees do not need to fill out a new I-9 unless they have an event that necessitates re-verification under the
provisions of the Immigration and Nationality Act.
The I-9 can be found here: http://www.uscis.gov/portal/site/uscis/menuitem.5af9bb95919f35e66f614176543f6d1a/?vgnextoid=31b3ab0a43b5d010VgnVCM10000048f3d6a1RCRD&vgnextchannel=7d316c0b4c3bf110VgnVCM1000004718190aRCRD
