Thank you Amir79, 2011July 20 and Cam1234!
I have been living in Canda since May 2009. In between, the file got transferred from Buffalo to Ottawa. We did our first medicals in Oct 2012. Later I was asked to submit my the RRPF during Feb 2013. Then no news...until I requested a GCMS note in August 2013. The same month, I was asked to submit the all the documents including my "original work permit"(no photocopy), police clearence of my husband from the home country, IELTS, graduation details, employment letter and bank statement. I did not go for second IELTS and sent the photocopy of my old IELTS along with rest of my documents and the visa officer called me for returning my original work permit. We had a nice chat and I requested him to take a decision on my application. I told him I don't mind if you take a positive or nagative decion as I am not getting young anymore and I want to settle down. I told him that I can not get hold of your office by phone or email. Visa officer promised that he will respond back to my emails and he promptly did too!
I went to MP many times..but I got only standard answer (under process...will contact if we require any additional info).
It was then followed by some uneventful months. Later I decided to ask for another GCMS note in Jan 2014. Then I got a second medical request. I did medicals for myself and not for my family family members as they just completed their medicals for TRV in Sept 2013. But CIC got back to me saying that they need remedicals for my family members. My family did the remedicals on 28th Feb and we received PPR on March 3rd at 10pm!!
From my experience, I think when we ask GCMS note, the visa officer at least goes through our file...
