Is there any remedy for the expiration of the US green card?

Q: When I was in the fifth grade of primary school, I got a green card by emigrating from relatives in the United States and lived in New York with my parents for four years. For some family reasons, my mother and I moved to Osaka four years ago (my mother has permanent residency in Japan). It is reported that the green card in the United States has a period of six months, but because of my parents' divorce, my mother and I live together in Japan and have no chance to return to the United States once every four years. I want to visit my father and friends in new york now. Excuse me, Mr. Tang: My green card has expired. Will it be revoked permanently? Is there any remedy? What are the procedures for visiting relatives and friends in the United States this time? Lawyer Tang: Your question is more complicated. Generally speaking, green card holders have not returned to the United States for four consecutive years. If they can't prove some connection with the United States, their green cards may be revoked. Of course, before revoking your green card, you will usually be given an opportunity to explain. If you can convince Immigration that you haven't given up your desire for a green card in the United States, you can't go back to the United States for a long time because of special reasons. For example, your father is in the United States, you have an American address and bank account, you file tax returns every year, and so on. Your green card may not be cancelled. I suggest you take this case seriously and handle it carefully. Good luck.
