Q14. I have renewed my passport now but the Chinese visa on my old one is still valid. Can I go to China with both passports without applying for a new visa?
A: You can travel to China on the expired passport containing valid Chinese visa in combination withthe new passport, providedthat the identity information (name, date of birth, gender, nationality) on both passport identical. If there is change to any of the above details, you must apply for a new visa.
