Reprinted from USCIS:
As of August 14, 2009, approximately 45,000 H-1B cap-subject petitions had been received by USCIS and counted towards the H-1B cap. Approximately 20,000 petitions qualifying for the advanced degree cap exemption had been filed. USCIS will continue to accept both cap-subject petitions and advanced degree petitions until a sufficient number of H-1B petitions have been received to reach the statutory limits.
