U.S. Citizenship and Immigration Services reminded employers that "As of March 10, 2010, USCIS will reject any H-1B petition filed without an LCA certified by DOL."
On November 5, 2009, USCIS had temporarily allowed H-1B petitions to be filed with uncertified labor condition applications (LCAs), "due to delays associated with Department of Labor’s (DOL) “iCERT” system." The USCIS reminder states that this temporary policy expired on March 9, 2010, and that USCIS will not renew it.
