请问8老师：I-797和I-797C的区别是什么？

-I-797 is the formal receipt or approval notice. I-797C is the copy of that receipt or approval notice. But it is not different to you (beneficial) and you can use any one copy of these two as the proof of your case.

什么人或什么时候应当收到I-797C?

-I-797C is sent to you (beneficial).

谢谢。
