I just got our brown envelopes L_Y, it is the same big format as they usually send extensions, ect. in. My fingers are cressed for you, I`m positive that you get AIP/PR at the same time. :-*
Mark_Anna, I submitted the police clearances with my original application and just to make sure, I got new ones before I was very close to the AIP date. I wanted to avoid anything that can slow the process down. I was approved for AIP/PR at the same time and I do think it was because I sent everything all together and my polices clearances were in the 1 year validity period. Try to get them as soon as you can, but be prepared to wait an additional 90 days from the time they receive them. Usually it takes that long to look at your file again after additional documents are added. Good luck!
