Can I apply for a replacement of the American green card in China when it expires?

You can't apply for a replacement in China when the US green card expires. Without this statement, you can only apply for a replacement in the United States. According to American immigration law, green card holders must stay in the United States for six months every year. If it is more than half a year, you must apply for a relocation permit. You haven't been back to the United States for a year, so you must be careful in this matter to avoid your green card qualification being cancelled. /zd/lx
