I suspect it would be real fast if the cap is determined upon the issue of AOR as seem to be implied from the following extract of the Ministerial Instruction & OP 6 - "A maximum of 20 000 Federal Skilled Worker applications, without an offer of arranged employment, will be considered for processing each year".
As for the comment by someone who had his or her application returned, I am not sure if it is the same thread which I had also read - but if it is, than I have my doubts from the very short turn round time the application was alleged to be sent and returned.
My advise to anyone who is still having second thoughts..dont wait any longer. Have you application submitted as soon as possible!
