Hi, I landed this May and haven't received my PR Card yet. I really want to go to the US for few days in the coming week but couldn't without the PR card. I realize that if I come back by road via a private vehicle I can do with some other supporting document instead of the PR Card to enter. I'm wondering is it possible for me to go to Niagara falls and then just walk back through Rainbow bridge? I've search everywhere but I can't find anything related to this way. Thanks
