... in response to k1 visa question visiting canada from US, posted by mudd on Jul 11, 2003If you cross a border,, and say 'Hello' to any customs official at that border, your wife or fiancee will need the correct documents. For Canada she will need a visa unless she has the green card, and more important, when you return, you want that green card, (or advanced parole), so she can come back home with you. We visited Canada last fall, and the Canadian official looked at the documents much more than the American official coming back, and my wife has the green card.
