On May 4, 2015, U.S. Citizenship and Immigration Services (USCIS) announced that it has completed its data entry of all fiscal year 2016 H-1B cap-subject petitions selected in its computer-generated random lottery process. USCIS will now begin the process of returning all H-1B cap-subject petitions that were not selected in the lottery. Due to the extremely high volume of filings for fiscal year 2016, the time frame for returning the unselected petitions is uncertain. USCIS has requested that petitioners not inquire about the status of cap-subject H-1B petitions until they receive a receipt notice (indicating selection in the lottery) or until the unselected petition is returned in the mail. USCIS will issue a further announcement once all the unselected petitions have been returned.
