i am a canadian citizen. my 3 year old son is a canadian citizen born in china. my wife holds a canadian permanent resident card and an expired chinese passport. we would like to return to china to visit in-laws in the near future. obviously she's going to need to get a new chinese passport before we travel (any idea of how much, etc?). my son and i will also need visas (my son is 3). is this all done at the same office? now that she's a permanent resident, she no longer needs a visa to return to canada, correct? am i missing anything?
