我想帮我妹申请亲属移民，应该也要列我外甥的名字，不知道这算有移民倾向，影响他办留学签证吗？
-No. He does not need to report your I-130 in his F-1 application because it is irrelevant to him.
另外我也想等我妈来美后给她申请，我是需要给我妈办完后再给我妹申请，还是现在就可以给我妹申请？
-You can do it any time. Your sponsor to your sister does not affect your sponsor to your mom, vice versa.
谢谢。
