Just wanted to see if someone knew this answer quickly.

I'm currently on a multiple-entry visa expiring in 10 months, however, my passport pages are almost completely full. My guess is I would need to obtain a new passport, what will happen to my existing visa that does not expire for 10 months? Also, I am not planning to go back to Canada any time soon, will I be able to renew my passport while in China (or must go to HK?) along with a new Chinese visa if required?

A friend of mine is in a similar situation with few visa pages left on his passport, but he's got a Residence Permit and wonders if there's a difference.

Thanks in advance for any comments.
