So I want to visit my boyfriend for the summer but I heard you can only stay thirty days. I eventually want to move in with him. We have been together for over three years and have kept up a strong long distant relationship. Is it possible to visit him and leave for a few days and come back to stay longer? Also with a illness is it harder to move to Canada because of it? I have Lupus and another chronic illness and I think it may stop me from moving in with him.
