From you other thread I understand you applied inland through cic vegreville? If you did usually you do not send off your passport you will get a letter usually 1 - 3 months after decision made from the cic nearest to you (sometimes it's really fast sometimes slow depends on the office and the time of year) you will become a PR at this interview. They will stamp your hubbys passport also at this time and he will obtain his COPR. Generally all family class applicants go through the in Canada landing process and no longer border cross. Not sure how it works for people in rural areas far away from a cic, but this is the procedure now. But if you do plan on going to Vegas understand that you can potentially have problems boarding an inbound flight to Canada without holding the PR card. The COPR isn't accepted by commercial carriers proof of status so flying back 'could' be problematic until you recieve the pr card
