The green card spouse of an American citizen wants to live in the United States for three years. How long can he apply for citizenship?

"If you have a green card, you must live in the United States for at least 180 days a year, otherwise your green card may automatically expire." Responder: tongspinellitongspinelli is not like this. If you hold a green card for more than two years, it will be invalid unless you enter the United States. If you live less than 180 days a year, you are not satisfied with your work every year, but you just can't qualify for citizenship. It has nothing to do with whether the green card will expire. If you become a citizen through naturalization, you can apply for a marriage green card after living for three years and a non-marriage green card after living for five years. The condition of naturalization (green card for marriage) is that you must live in the United States for at least three consecutive years 180 days. As long as this condition is met, you can apply. The permanent green card is renewed every ten years. If you are not naturalized, you can live in the United States forever with a green card. But not more than two years, not allowed to enter the United States. There is no such restriction on becoming an American citizen. Come to China with a green card, use a China passport, and use a travel permit without a China passport (overseas Chinese from Hong Kong, Macao and Taiwan, etc. When you become an American citizen, your China passport will be confiscated. If you want to go to China, you need a visa, and your stay in China will be limited. (Up to three months, determined by the immigration officer of China at the time of entry). If you don't think you have enough time to stay in China, go to Hongkong or Macau, and then re-enter (China), and the stay time will be recalculated. You'd better ask an immigration lawyer about naturalization. There are many precedents in American law, and different special cases can be applied.
