回复：替姐姐姐夫办美国移民时 出现的问题

填130表时发现
姐姐和姐夫的申请必须分开填
-You can not sponsor your 姐夫 GC application directly, but your 姐夫 and your sister's kids (if any) can get their immigration visa as the derivative status of your sister's GC application. So, you just need to file one I-130 for your sister and list your sister's family members'names in the Form I-130. That is all.

1）姐姐的申请，可以公证姐弟关系。

2）姐夫的申请，该如何证明与其关系？
-You do not need to 证明 the relationship between you and your sister-in-law.
-
需要公证姐姐姐夫结婚证吗？
-Yes. This document must be needed.

那位知道，在这先叩谢了！！
