1. Proof of US Status: 这是指我入籍时拿到的公民纸吧?
-Either copy of 公民纸 or copy of the US passport.
2. Proof of relationship (only for I-864A): 因为我和妻子共同报税,所以填写了I-864A以表示她的支持。那么,这里的 Proof of relationship 是指我们的结婚公证书吗?
-Whose parents, yours or your wife's? If hers, she needs to the copy of her birth certificate and also, a copy of your marriage certificate.
3. 两份材料邮寄时是在一起寄(内部用塑料袋分开),还是干脆放在不同的包裹里?
-Fine. Follow the NVC Instructions.
放在一起会不会让工作人员更困惑?
多谢帮助!
