No that is not the reason your ppr is coming later than your friends,I have submitted pof even though it wasn't required under cec class.I do firmly believe it depends on luck, agent working on your profile and some other unknown reason!!everything will be ok!My colleague's AOR: 21 Aug. He received PPR last week.
He is also CEC class (same as mine). and he showed POF.
Since POF is not required for CEC class, I didnt show this. Is this the reason for getting late to receive PPR?
