The label says the milk is expired, but can you really drink it?  The U.S. Citizenship and Immigration Service (USCIS) announced through its website that employers should continue to use the current I-9 form after August 31. The current I-9 form was revised August 7, 2009 and “expires” on August 31, 2012. The USCIS announced that employers should continue to use the current form even after the August 31, 2012 expiration date has passed, and USCIS will provide information about a new form as it becomes available.
