I'm interested in hearing others' feedback as well! I'm also considering sending medical before its requested, however, I'm not sure how they would link it to my file, as I don't have a UCI number (only my sponsor does). Would that me enough to connect the two documents? Does anyone else (sponsored) NOT have their own UCI? I'm feeling a bit anxious about it, because it seems like everyone does!
I did ask for input on the 2012 thread and got the following response from QuebecOkie:
"I was advised by a CIC call centre representative NOT to submit the medical and police check before CIC requested them. (I didn't leave them out intentionally, I just lose about 40 IQ points the moment I look at a CIC form, and I somehow didn't realize I needed to include them.) I stressed over the decision a lot, but I ended up deciding to do both before they were requested.
This caused a *great* deal of confusion at the doctor's office. They tried to tell me I couldn't do the medical without the form from CIC (CIC sends you a form when they request the medical). I told them I wanted an up-front medical, but they were confused because my app was already submitted. In the end, I got what I wanted, though the doctor made very clear that he wasn't to be held responsible if my results were not properly matched up with my file (since I was doing it "wrong"). I noted my UCI number clearly on the doctor's "up-front medical" forms. (There's no place for the UCI on the up-front form, I just wrote it in where there was room.)
I sent in the proof of medical and the police certificate about three months after AOR. I sent a CSE (case specific enquiry) two months later to see if my documents had properly been matched to my file. I sent a follow-up after more than a month of no response to the first CSE. Finally, after more than two months since I sent the first enquiry, I received confirmation that both documents had been received and matched to my file.
For me, this worked out for the best, as I received AIP and DM at the same time (after more than a 10-month wait after AOR). Had I waited for CIC's request, it would have taken months more for DM. However, I can't say I "advise" you to do the same. I took the risk of them losing my documents, having to pay for medical twice (it was almost $400 where I had it done), and delaying my process anyway. I'm happy I did things the way I did, but I did it with the knowledge that I was risking spending money and time for nothing."
