U.S. Citizenship and Immigration Services is working on several revisions to Form I-9, including expansion of the form to two pages, expansion of the instructions to six pages, changes to Section 1, and a revised layout.  The new version has not yet been approved so employers should continue to use the version of the form with the expiration date of 8/31/12 until the new one is posted at www.uscis.gov/files/form/i-9.pdf.
