Can I go back to China immediately after I have got the American green card?

You can leave the United States and return to China during the application for a green card.

Once you leave the country and return to the United States, the Immigration Bureau may turn your overstaying status into illegal residence. According to the immigration law, a person with an illegal residence record of more than 18 days can be punished for not returning to the United States for 3 to 1 years. Therefore, it is best to avoid leaving the United States and re-entering the country when waiting for a green card. After receiving the applied green card, there is no problem to leave the country.

It is stipulated that those who leave the country for more than one year must apply for an I-131 re-entry permit to the United States in advance, which is commonly known as the "white paper". Those who have lived for more than six months need to prove their willingness to live in the United States with tax return records. Even if you apply for a re-entry permit to the United States and prove your willingness to live, even if you leave the country for less than three months, the immigration officer has the right to decide not to enter the country or even confiscate the green card on the spot. /zd/xx
