Re : File transfer date
I heard this from a lot of my friends who heard it from insiders and i agree to it.
When you get the letter approval from CPC miss it usually says that your file was transferred the same day when it was approved.
Actually, they send the files in batches to India. Regardless of when they say the file transfer date the actual date is the one which you see in ecas under PR status when it says app received..we received your file on xxx date
In my case this date is Jan 4 which is a lag of 12 days from approval, not sure if this info is true but makes sence.
