I sent an urgent request after I received AOR recently as I have a job opportunity from government that requires citizenship and high security clearance. I called IRCC this week and the agent said my file had been reviewed and accepted in urgent processing department and they should be processing it urgently. I am not sure if it's really been accepted or my file is just there because of the request... There's a deadline for the job opportunity so if IRCC couldn't process it within the time frame, I assume they will just process my application normally. I wouldn't have high hopes on it. Unless they really couldn't find other candidates to fill the position... Also urgent processing isn't necessarily faster and I've heard that some local offices just don't do urgent processing. It just doesn't happen often.
