Some folks are predicting that H-1 quota may last a lot longer than just April.
Remember also, if there is a lottery, ALL cases received by and including 5 April will be included in the lottery. As the regulation 8 CFR 214.2(h)(8)(ii)(B) states:
Premium Processing for Cap-Subject H-1B Petitions to Begin April 15, 2013
Released: March 15, 2013
WASHINGTON: U.S. Citizenship and Immigration Services (USCIS) announced today that it will begin accepting H-1B petitions subject to the Fiscal Year (FY) 2014 cap on Monday, April 1, 2013. Cases will be considered accepted on the date that USCIS receives a properly filed petition for which the correct fee has been submitted; not the date that the petition is postmarked.
