I can present one of a myriad reasons for urgent processing, my parents being terminally sick and needing urgent care etc etc, you name it. Can they deny the request? Yes they can; anything CAN happen.
As for your statement that my request WILL be denied, unless you are the officer adjudicating my case, you are really in no position to make that claim. That much should be obvious. With that being said, I don't why you'd want to embarrass yourself in here by making that claim. Do you really believe I got as far as acquiring Canadian citizenship by having my applications denied?
More to the point, if you don't have a proof of citizenship application in process, I'm really not sure what you're doing in this thread. There's nothing about my case YOU can tell me, as far ahead as I can read. I think your soup is getting cold.
