My wife and I both currently live in the US. We lived in Canada for about 5 years, and while there she became a PR. I am a Canadian citizen. We've been living in the US for the past 4 years. We've visited a few times, but all while her Canadian PR card was valid and she still met the residency requirements. Now, her Canadian PR card is expired and she no longer meets the residency requirements. Will there be any issues for her just visiting Canada?
