OMG! IT DOESN'T MATTER IF YOU DON'T PLAN TO LEAVE. YOU CAN BE IN CANADA THE ENTIRE TIME! stop questioning it and accept it as true already, since it is. there are hundreds of people on this forum that have done this and are currently doing this. to land, all you have to do is drive to a border. do you see ANYTHiNG that says otherwise? please inform me where it states a person MUST be out of canada during the entiring processing of their PR application. THERE IS NO SUCH THING!!!!!
As for the interview, 99% of US applicants are waived the interview, and it really shouldn't be a reason to get stuck in inland hell. if you have a straight forward case, you don't have dependant or criminal issues, and you leave 0 room to question your application, then more likely than not you will NOT have an interview.
obviously you are trying to rationalize your decision. none of it is based on FACT seen by REAL LIFE OUTLAND APPLICANTS FROM THE US! It appears to be based on made up nonsense from people who don't know the process and assumptions being made from non-legitmte sources!
I really really really hope someone comes by and posts EXACTLY where in the inland application it actually SUGGESTS TO APPLY OUTLAND TO TAKE ADVANTAGE OF THE QUICKER PROCESSING TIME. not that it matters, you made your mind up, and don't really sound like you want to hear any different that what you assume is "correct" when is it so very wrong.
