Can I go back to the United States for political asylum as soon as I get a green card?

You can't go back to your original residence if you get a green card on the grounds of political asylum. The reason is that you are politically persecuted in your original place of residence. The U.S. government approved your residence on humanitarian grounds, but once you get a green card, you will return to your original residence. In other words, what you said to the U.S. government before about persecution in your original place of residence is a lie, and you obtained your green card status by deception. When you re-enter the United States, the Immigration Bureau will cancel your green card and refuse you entry. Please think twice! ! !

After becoming a citizen, you can go back to your original place of residence, because your identity has changed and you are an American citizen.

You must live in the United States for five consecutive years to apply for naturalization (you can't leave the United States for more than six consecutive months), and you must pass the exam to become a citizen.

If you want to return to China as a citizen, you need to apply for an entry visa at the China Consulate.
