回复：NSC RFE 的回复递上多久,会听到消息.

Really depends how many materials you submitted for your RFE. In my case, I submitted a lot of materials for my RFE, so i guess NSC will take time to check. I heard some of friends got approved within one weeks. But i think one week is norma. so do not worry, you will get approved soon. Good Luck!
