1. 侄女一定需要回国面试才能拿到绿卡吗?
-Not have to.
若不回国,如何操作?
-After her father enters US using the immigrant visa, then she can file I-485 within US to get the green card.
2. 侄女若回国面试, 要拿到绿卡, 是不是一定要和她父亲一起来美国才能拿到绿卡?
-Yes. She must enter US together with her father or after her father enters US.
侄女的绿卡申请是付在她父亲我哥哥上的。
非常感谢!
