My girlfriend lives in Canada and I'm from the US. I am currently planning on going up there in May and saying I'm visiting my girlfriend for the summer (4 months) and then at the end of the four months applying for an extension. My only ties back home are college and my house which I rent , my lease is up in June so I doubt this will help me. My question is can I do anything to make sure I'm allowed to stay there ? will school be enough of a tie? and how much stuff can I bring with me without looking suspicious?
