Q: What should I do if my passport is expiring but I still have a valid Chinese visa and residence permit in it?

A: If your passport is close to expiring but contains a valid Chinese visa and residence permit, you can apply for a new passport and keep the old one. When traveling to China, present both passports, using the new one for identification and the old one for the visa and residence permit. As long as your details match in both, you will be allowed to enter. Even if the old passport is marked canceled, such as with a hole punch, the visa and residence permit remain valid.
