Hi, I've been trying to help my dad get a visa to china. He is now a US Citizen, but was born in Hong Kong. Visa application for china requires that anyone born in China need to have their old chinese passport. My dad has his Old Hong Kong passport when it was till under British rule and his naturalization papers as well only. They said that his chinese name is not on the Hong Kong passport and that they need something with his chinese name on it. I tried to explain that it was under British rule at the time that's why there's no chinese name. My father doesn't have any documentation of his chinese name, he has long ago lost it all over 45 years ago. They just tell me to have him look for it. Does anyone have any advice on what to do?
