I'm a new PR and have not yet moved to Canada but want to get a SIN. (I realize that right now they're only processing urgent requests, but I can't start work without a SIN so I'm hoping my request will qualify.) According to the government website you can apply for a SIN from outside Canada. I'm thinking of doing this but not sure about the logistics --specifically, whether I should use a courier service and send a return envelope or just use registered mail. Has anyone here applied for a SIN from outside Canada? If so, how did you send your documents and how were they returned? How long did it take? Thanks.
