U.S. Citizenship and Immigration Services will begin accepting H-1B petitions subject to the fiscal year 2018 cap on April 3, 2017. All cap-subject H-1B petitions filed before April 3, 2017, for the FY 2018 cap will be rejected.
As of August 28, 2009, approximately 45,100 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to reach the statutory limits, taking into account the fact that some of these petitions may be denied, revoked, or withdrawn.
