回複:父母申請綠卡如何申請 =>
A United States citizen who is at least 21 years old can apply for or “sponsor” his or her parent Green Card application to live permanently in USA, and there is no annual immigration visa number limit for a U.S. citizen's father and/or mother immigration. Parents of U.S. citizens are eligible to apply for US Green Card as immediate relatives. Also see http://www.greencardfamily.com/parent.htm
