By the grace of Allah Almighty and lots and lots of patience (of 6 years, 9 months & 8 days), I've finally received PPR1 request. I applied for Quebec Investor in Jan 2008. On 15 Oct 14, I have been asked to submit passport biodata page & "Updated Information Chart" within 10 days (which I did send to LVO the very next day).
Now, waiting for PPR2 request from Islamabad VO.
In those 6 years, I have given medicals twice & refurtherance medical once. Only recently, my CIC online file is not showing 'decision made'. Latest entry is showing that 'medicals have been received' and then I got PPR1 request. Hope everything is fine now.
