I thought as long as I live with a Canadian citizen, renewing an expired PR card would not so difficult...
I should really look into this problem more.
I read that a PR status is intact even after the PR card expiration as long as the PR obligation is fulfilled.
I guess the reality is not exactly what the law states.
Thank you so much, I really appreciate your reply.
The PR status is intact as long as the PR obligation is fulfilled. However, there are no means in place for PR's who live overseas to renew their PR cards. You have a couple of options there.
1) Try to renew your PR card through the mail using a Canadian address. Immigration rules state that you do not have to physically be in Canada to renew your card but your application to renew must originate in Canada and if you are asked to pick up your card in person, you need to show up.
2) Go to Canada and apply to renew your card, possibly asking for expediated processing and showing a ticket back or just leaving again, hoping that they will mail it to your Canadian address for you.
3) Don't renew your card and wait if and until you move to Canada again and then apply to renew. You can always get into Canada by getting a travel document as long as you meet the requirements.
