Hi everyone. I want to explain my situation and ask for your suggestions. I am a Phd student in the UK and want to visit an university in Canada for research purpose. I sent an online application for myself and my wife together. I received a worker visa while she has a tourist visa. Now, everything seems ok but except the one thing. On the application letter from the university, it was indicated that I will visit them between Sep 30 - Oct 30; however, because of some issues, I prefer to go there a bit late and arrive on Nov 2nd. Therefore, even though I asked them to leave on Nov 2nd, my visa is valid until Oct 30 while that date is Nov 2nd for my wife. What should I do? Am I allowed to stay 3 extra days in Canada? Thanks for your time.
