After you entering canada it will take 45 days to 3 month to get your PR card. The PR card they will send your designated address in Canada. You can re enter to Canada any time when you get the PR card.I wana know one more thing. I am working in UAE. Right now i cannot quit my job and i have to enter canada before my medical expires and they are expiring end of next month. Is it possible if i can enter Canada for 2 3 weeks now and, Once i get my PR done then i come back and sort out my things here in uae and then i i ll go back to Canada for real after 6 months.
However you can return to UAE after two/three weeks. But before that you have to ensure that someone should receive your PR card in Canada and sent to you in UAE through DHL or Fedex. It would be better if you go back to UAE after receiving the PR card.
