As of May 1, 2009, approximately 45,000 H-1B cap-subject petitions and 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to reach the statutory limits, taking into account the fact that some of these petitions may be denied, revoked, or withdrawn.
