Ok. Thanks for taking the time to respond!! He will be happy to hear thisif an Immigration Officer called the lawyer that is a good thing, the file will surely 99% approved for AIP. If you can see the first applicant here on this thread first (1st) page, she didn't received any AOR for long time and then she received call from Vancouver office and they asked about her son. She got approved AIP.
Me too, I received phone call from Immigration Officer from Vancouver and the day after the call I received my AIP, after the call. Same day she made her decision for AIP
