You are a Canadian citizen so will have no problems returning to Canada.I won’t. We decided I should stay a longer time, because we’re not sure how long is going to takes his process. And because we didn’t feel right just to get married and leave. But the only reason that I’m here is just for him. I’m not planning to stay. My family, my whole life is in Canada. And my only purpose is have my husband with me.
My only concern is if I’ll have any issue returning to Canada after being out for a long period. But this is my first and last time.
Since you will be banned form re-entering the US for some time, just be prepared that you may be separated from your spouse for well over 1 year while you put together the PR app and wait for it to process. In hindsight you could have submitted the PR app some time ago while you were living together in the US, to get the process started.
No matter how strong you make your app, it's entirely at the discretion of visa officer reviewing it if they decide to request an interview or not, and if so where that interview will be held.
