Can I go back to work when I get an American green card?

In theory, you can return to China if you get an American green card. But it is not recommended to leave the United States for more than half a year, otherwise the customs will make things difficult for you when you enter the customs next time. We may even warn you that since you have no intention of staying in the United States for a long time, we have the right to withdraw your green card. However, at present, the laws of the United States have not been revised, and the customs only say this to scare you. He can't really cancel your green card. But he can take you to a small room and force you to fill out a declaration of voluntary abandonment of your green card.

So if you really want to maintain your green card, you'd better not leave the United States for too long. Simply put, if you have an American green card, you must land in the United States every 180 days, and you can apply for American citizenship after living in the United States for three years within five years, that is, you can cancel immigration supervision. To be on the safe side, let's apply for a re-entry permit to America.
