In past years, both the US Master's and Regular H-1B caps were met within the first days of filing; whereas, this year, USCIS is still accepting petitions beyond the initial five (5) business day filing period. It remains to be seen for how long the H-1B visa cap remains open and available.
U.S. Citizenship and Immigration Services (USCIS) recently announced that that it will continue to accept H-1B nonimmigrant visa petitions subject to the 2010 cap till it receives sufficient number of petitions required to meet the H-1B cap for FY2010.
When the USCIS declares that the H-1B visa cap is met, all cases receipted on the last day will be subject to a random lottery. Until the USCIS declares that the H-1B visa cap has been met, cap-subject H-1B cases may continue to be filed.
