Had our interviews this morning. Arrived about 1/2 hour early and they took us right away. Interviewed all 4 of us together. The whole process took about 45 minutes including waiting. The questions were just to verify our information on our applications forms. My 16 year old son didn't bring his driver's license but fortunately it wasn't an issue. Remember to bring every possible piece of ID as they may ask for it. We then went to the Canada Customs office on the other side of the border and had our iris scans done and now we wait. Had to laugh the US Customs officer was so serious and the Canadian one was happy and chatty Looking forward to getting our cards in the mail soon!
