No Immigration Authority in the entire world would ever tell you their inter-working and how applications are be looked at ,nor do you have the right to tell otherwise if you aren't aware of there working processes.
Now , is it frustrating to see other applicants with AOR after us getting PPR ? yes it is! but then why would we care anywhere? We all will get it someday, so move on and do something with your life instead of just basing your head around waiting for the ''Golden Mail'' to arrive.
Also, if you look at things holistically, Canada is the only country with the fastest , cheapest and most accessible immigration system in the world right now, aside from other third world economic and political immigration systems. So, why don't we all appreciate that for a moment and let things take it's own course ?
That's my two cents!
