How hard would it be for a friend of mine to cross the border by greyhound bus from the us into canada (through Bangor, ME if it matters) with just a one way bus ticket instead of a roundtrip one? He's going to be coming up to visit me for a month, staying with me, and I'm planning on paying for the ticket back. Will the customs officers give him trouble/not let him cross if he doesn't have a round trip ticket? I've had trouble doing the same going from Canada to the US myself, so I want to check if it's as bad coming into Canada from America before he gets his ticket up here.|||bad idea, he will need a return ticket yes it is as bad as coming the other way
