I checked out your message pretty late, but I'm falling into the category. Crossed 6 months last month (Apr 18th) and had called up CIC a few days back only to find out that my application was transferred to NDVO on 6th April. File is gathering dust at NDVO ever since. Did you get your PPR yet, if yes then how long did they take and did they do anything additional after receiving your application other than issuing PPR and stamping VISA/COPR?
