MY husband landed on April 10th and has not gotten his PR card in the mail yet .. (We know this can take 2 - 3 months) We were told he can't fly in and out of Canada until he gets it - the paper documentation isn't good enough. He is American. I would assume he can fly to the USA using his US passport (he's American it's not like the USA isn't going to let him in) and then he can drive back to Canada .. (they told him he can drive with his paperwork before he gets his PR card) Does anyone have any experience with this ?
