I have two problems providing such proof:
1) Living in China, I don't have ready access to English newspapers, and paying to translate the entire front page of a Chinese newspaper (once per month) just to get the date entered as evidence seems expensive. (Some people might suggest that the newspaper need not be translated, since the date will be in Roman letters, but I assume that Canada enforces to the last letter its requirement that any document be translated into English or French, without exception.)
I used to live in Shanghai, China, but I can find English newspaper such as China Daily in my neighbourhood newstand and major bookstores. I think you can order it through your local post office
2) I have tried to print English newspapers off the Internet, but the dates are extremely small, and are almost invisible in a photograph large enough to show our two faces (my wife's and mine).
Do you use ATM bank machines? You can print out receipts for free daily
Anyone have new solutions to these two problems? Actually, solving problem 2 makes problem 1 go away.
And finally, renewing a PR card requires the PR to be in Canada. While it is true that a PR can perpetually renew his/her status while living abroad with a Canadian spouse, applying for a new PR can be done only in Canada, and the PR must personally go to a local CIC office to pick up the card. Since it can take a quite a long time between application and PR card retrieval, the PR must either spend a few months in Canada, or fly back and forth, getting a travel document (allowing entry into Canada without the PR card) each time. This is expensive.
Not quite. If you can manage to turn your credit card pts to asia miles, you can save some money in redeeming a round trip plane ticket between YVR and PEK/HKG or hotel package.
I'm not trying to be negative; just preparing those abroad for difficulties at renewal time.
