zw, if you are already in Canada and you have a job offer, the docs might be different anyway. If you've been in Canada the entire time since you applied for PR and you haven't left at all, they might not even ask for a police certificate (you never know...). Additionally, if you have left, there seems to be some question as to whether they will request the FBI or local/state police certificates, as that varies from person to person, so it's difficult to predict in advance. And, for some of the documents like proof of funds, you can't do that too far in advance because the whole point of their request is to verify that you currently have the amount you need. You can fill out the generic IMM forms but that's about it at this point, and you never know, they might not request more. As you are a fellow 2011 applicant, expect them to at least ask for the IMM form updates (which are almost identical to what you sent in your original application, just updated since it's been 2+ years), and since you are an FSW1, expect a proof of funds request. Additionally, they might ask for a reference from your current employer (or school if you are a full time student) just to verify what you are doing right now, and that's something you can probably get done ahead of time. The forms will probably be IMM0008, IMM5669, IMM5406, and IMM0008.3e ("Schedule 3"). That's what they asked me for and you and I have similar timelines and are both FSW1.
