我兒子在國內，和我前夫生活在一起，現在10歲半了。請問：我前夫有孩子的撫養權，如果我想為我兒子辦綠卡的話，需要我前夫的書麵同意嗎，還是需要法院的判決？
-Yes. Had better get the official document from the court.
我現在的丈夫是美國公民，他可以幫我兒子辦綠卡嗎？
-Yes.
如果可以的話，需要什麽材料證明他們的關係呢，
-Copies of your current marriage certificate (show you and your spouse relationship) and your son birth certificate (show you and your son relationship). Thus, your son connects to your spouse.
我現在的丈夫算是我兒子的繼父嗎？
-Yes. Then, your spouse files I-130 for your son immigation visa application jus like he did for you.
感謝不盡!
