回複：代朋友問：女方持婚姻臨時綠卡，有一子10歲在國內，如想給孩子申請綠卡，

可以先申請B2探親簽證來美嗎？
-可以.
有沒有可能拒簽？
-Anything is possible. But most likely the kid will get the visa because the child needs the mother to take care and the visa officer knows it.
如孩子來美後申請綠卡，要排期嗎？
-Yes, if the mother is the sponsor. But If the step father (US citizen) agrees to sponsor the kid's green card application, no 排期. Anyway, the mother has to have the child custody right issued by the court.
