It will take shorter than that.
Don\'t worry, NSCNOHOPE, it will take short than that, at least in CSC if there is no other issues.
I talked to an officer in CSC earlier this month, she told me that a case would be assigned to an officer within 60 days after CSC had received the response to RFE. So, if there is no other issues, the case would be approved soon after that.
Keep your hope high and you will be there, with a little patience.
