How long can you stay in China with a U.S. Green Card?

After getting a green card and returning to China, you can stay for six months. To maintain the validity of your U.S. green card, you need to enter the United States at least once every six months. That is to say, you can return to the country and stay for up to six months continuously, otherwise the US Immigration Service will doubt whether you really want to become a permanent resident of the United States.
