I sent my application PR application on March14th and got my File number on April 22nd. Does this mean that my application wont be returned back? I am asking this because after I sent my application I found out that I made some minor mistakes in my application. So, after reading few articles about it I found out that CIC sends those forms back asking to correct them. So, I was wondering if that happens after receiving file number or before? In other words, is there still a chance that even after getting a file number my PR application could be returned because of the minor mistakes I made?
