It took about 8 months, not 10, from document submission to request for medical. It took us almost the whole 90 days to round up all the documents in Ukraine, have them sent to Canada and get them translated.
No additional documents have been requested. In early August, 2013, we received a letter asking for the PRV application. It took a while to round up all the documents and all was sent in late October, 2013. At this time we sent the PRV application, police clearance, all other requested documentation, and paid the "right of permanent residency" fee.
Received a letter dated Feb 6, 2014 stating that the sponsorship application was approved, and that the file was sent to CPP Ottawa.
Received an email Jun 26, 2014 with instructions to go for a medical. Medical was done on July 25, and I noticed about a week ago on CIC website that "Medical results have been received."
Now we are trying to guess what happens next! What is a realistic expectation? Other than a long wait, everything seems to be in order and moving along. I have seen some timelines on this forum that indicate that a visa could be issued 2-3 months following the medical. We are hoping this will happen in our case. Sadly, I have seen others where medicals have been redone after a year of inaction and people are still waiting.
