What procedures do immigrants need to go through if they want to live in China?

Have you been naturalized? You can still get permanent residence status. If you just get a green card, it is still easy to return to China. As long as you meet the residence requirements related to the green card, you can return to China at other times, because you are still a citizen of China.

Of course, if you naturalize in another country and lose your China passport, you will automatically give up your China nationality. Although there are relevant laws to restore it, the probability of success is very small. If you want to live in China, you need to apply for the relevant visa. Of course, you can consult the professional lawyer team of relevant immigration agencies, which is more professional. The above is my personal opinion!
