I have been away from Canada (accompanying citizen spouse overseas) for about six years, after living in CA for two. My PR card is obviously expired. If I travel back to CA (either with a travel doc or by land), can I apply for a PR card while on vacation in CA, or do I have to have established residency again? Optimally, I'd like to travel back for about thee weeks, apply for the card, and have familiarly mail it to me.
