Does getting a green card mean giving up China citizenship?

Getting a green card does not mean giving up China citizenship.

When a person (or a family) applies for immigration, after living abroad for a period of time, he (they) feels that he (she) can adapt to all the local environment, so he (she) can apply for special permission to stay in the country legally and permanently, and can enter and leave the country at any time, anywhere and any number of times. This permit is "permanent residency" PR (permanent residency). In many countries, it is a sticker, which is put in the passport of the approved person. In other countries, it is a card, such as the United States and Canada. Because the early permanent residence permit in the United States was a green card, it was named "green card" (although it is actually white now). After this title, people refer to the permanent residency of all countries as green cards.

"Permanent residency" and "nationality" are two different concepts. Nationality refers to the legal qualification that a person belongs to a national or citizen of a certain country, which indicates that the person has a fixed legal connection with a specific country and is the legal basis for the country to exercise personal jurisdiction and diplomatic protection. People who have obtained permanent residency in a country do not mean that they have also acquired the nationality of that country. They still retain their original nationality. Only when these people applied for the nationality of that country and were finally approved did they acquire the nationality of that country. Many immigrant countries in the world allow citizens to maintain dual or even multiple nationalities. According to the nationality law of our country, our country does not recognize that our citizens have dual nationality, so once a China citizen becomes a foreign nationality, it means automatically giving up China nationality. (Similarly, foreigners who have become naturalized in China automatically renounce their original nationality. )
