is it EVC? if so have u submitted letters from client and vendors?: yes.
The receipt we received from USCIS was a normal receipt (without mentioning premium processing - they ignored the cheque given for premium processing). Then employer called them, and received a 2nd receipt that said 'premium processing'.
I guess they sent the RFE for my case right on the 14th or 15th day.
Did you not even get a receipt yet? or, you have not heard anything after receiving the receipt?
Does the receipt say Premium processing? 4th row from the top of the notice, below the beneficiary name "notice type: Premium processing"
