According to a USCIS News Release: “U.S. Citizenship and Immigration Services (USCIS) announced today that it has received a sufficient number of H-1B petitions to reach the statutory cap for fiscal year (FY) 2015. USCIS has also received more than the limit of 20,000 H-1B petitions filed under the U. S. advanced degree exemption.
Before running a random selection process, USCIS will complete initial intake for all filings received during the filing period which ended today. Due to the high number of petitions, USCIS is not yet able to announce the date on which it will conduct the random selection process.
A computer-generated process will randomly select the number of petitions needed to meet the caps of 65,000 visas for the general category and 20,000 under the advanced degree exemption. USCIS will reject and return filing fees for all cap-subject petitions that are not selected, unless found to be a duplicate filing.”
