How do foreigners live in China for a long time?

I have many foreign friends, and many times they want to stay in China all the time, and then they will ask me related questions. Because my friend is an accountant, he often goes to the immigration bureau or goes through the relevant procedures for setting up a company, so I have a certain understanding of this:

1. Your husband is a foreigner, married to you, and you are from China, so he can stay in China as long as he becomes a citizen of China.

2. If you don't pass this method of 1, it will be more difficult. You must have a house in China, live in China for at least 10 years, and have no relevant criminal record. And a good reason to stay. So you can apply for residence in China and a "green card".

Regarding special conditions, if your husband is a researcher and a special person, for example, he has made certain contributions to China, such as charity, you can make an exception and apply for a green "green card" to live in China.
