I passed the interview last week, and the Officer requried me to submit passport within 45 days. But because It's very inconvenient for me to get the passport so soon, can I ask for a delay? (I heard that one can get the passport after LP). Besides, I didn't tell the change of my permanent address to the Officer, nor did he ask me during the interview. Will be there any trouble if it's different from that on application form when I land on Canada? Thanks.
