If you are prosecuted in China during immigration detention, will it affect Nayong's residence?

First, if you only have permanent residency in a foreign country (for example, a green card in the United States or a maple leaf card in Canada), you are still a citizen of China, travelling between that country and China with a China passport and a green card. You still need a China passport to apply for a visa to other countries. Naturally, it is impossible and impossible to give up the domestic hukou. Second, if you become a foreign national, take the United States as an example, then you have become an American citizen. American law recognizes dual or even multiple nationality, but China does not recognize it. If you need to return to China, when you apply for a return visa for the first time, the embassy or consulate requires you to provide your previous China passport, which will be invalid and registered. You can only apply for a Chinese visa to China as an American citizen with an American passport. However, after you enter China, your hukou and ID card are still valid. According to the relevant regulations, you need to bring your ID card and American passport to the household registration management window of the Exit-Entry Administration Office and fill out a form to apply for renunciation and cancellation of China nationality and household registration. If you don't go through this procedure, no one will take care of you, and your ID card is still valid. The hukou still exists, but every time you return to China, you must register with the police station in your jurisdiction within 24 hours after your arrival. Just don't let the police station admit that you are a resident of this area, or I guess they will urge you to cancel your account. A friend is like that. He has held an American passport for many years, and his account and ID card are still valid. It's no problem to fly to the bank. However, the visa for visiting relatives can only stay for three months at a time, so you must leave the country.
