Hong kong residents apply for home visit permits.

It's simple. After living for seven years, if you still hold a China passport and an American green card.

Then you have to go back to China to cancel your China passport and account (if so, I know many people take shortcuts now and don't cancel their accounts even if they get a green card). . Then based on these two things, plus the Hong Kong visa issued by the Hong Kong Immigration Department when you first settled in Hong Kong. . Then take these documents to China Travel Service in Hong Kong, and then ask the staff what to do! However, it seems that some documents need to be sent to the mainland, and the cost is about 150 Hong Kong dollars!

If you get a Hong Kong permanent identity card after seven years, you will already be an American citizen (holding an American passport). You must apply for China citizenship from the Hong Kong Immigration Department (and you must renounce your American citizenship). . Then you can apply for a home visit permit. . . But you don't even live in the United States, so you should not meet the requirements for applying for an American passport. .

If you have a bank account in the mainland, the easiest way is notarization. Go to a law firm in Hong Kong or a notary office in the Mainland to prove that the Hong Kong ID card and the previous Mainland ID card are the same person. After that, I won't bother you. . . It's that simple!
