New H1B Petitions - When does USCIS start

Hi Saurabh,

I have a general query regarding the H1B petitions. That is, When does the USCIS begin to work on the petitions for the new fiscal year? Whether it is after having finished with all the previous/preceding year’s petitions OR is it immediately on receipt of the new fiscal year’s petition (from 2nd of April for the current fiscal year) OR is it after the 1st of October?

Thanks in advance.

Current quota (FY2013) petitions are processed (from April 2012) along with the previous year petitions.

Its not after 1st October - thats the earliest date one who go approved H1B petition for FY2013 quota can start working on H1B status.
