What if the American green card expires in China?

I am in China, and I used to have an American green card, but it may be invalid or expired. What should I do if I want to go to America now? The solution is here! 1. If your green card has not expired, you can't apply for a green card extension in China, so you need to apply for a green card again before entering the United States, because it will be very troublesome to go back to the United States with an expired green card, and you may be refused entry or boarding. 2. If you have not returned to the United States for more than 1 year, the green card will automatically expire. Green card is permanent residency, that is, green card holders must live in the United States permanently. This intention of the green card holder is determined by the US Immigration and Naturalization Service through its behavior. This does not mean that green card holders cannot leave the United States. The important issue is that green card holders must be able to convince immigration officials that they really take the United States as their permanent residence and do not intend to settle in other countries. According to the immigration law, any non-American citizen must hold a visa or visa equivalent to enter the United States. Green card holders' green cards can only be used as visa substitute documents if they have been abroad for less than one year, and they can freely enter and leave the United States with green cards during this year. If he fails to return to the United States within the time limit, the green card holder can no longer use his green card as a visa substitute for entering the United States. In other words, if the green card holder leaves the United States for one year or more, the green card holder's green card is in danger of invalidation. Because in the eyes of immigration officials, this is equivalent to automatically giving up the intention of permanent residence. At this time, if you want to keep your permanent residence status, you need to produce enough evidence to convince the immigration officer that you have never thought of giving up your permanent residence in the United States, and your long stay outside the United States is caused by unforeseen reasons. If the immigration officer can convince the applicant not to give up the original intention of permanent residence in the United States, the applicant can still retain the permanent resident status. However, at this time, the cardholder can no longer use his green card as a visa replacement document to enter the United States, but must apply for a special SB- 1 immigrant visa at the American consulate to return to the United States. If you have no intention of permanent residence, you can just go to the American consulate for a short stay, return your expired green card to the consulate, formally give up your permanent residence status in the United States, and apply for non-immigrant travel or other visas to the United States. /zd/xx
