回复：Dear taoyun, are you willing to disclose what your RFE is

Don't worry too much. It depends on the message you received after USCIS received your RFE, definetly it will take less than the normal processing time after they received your RFE, since the premium processing has been completed. They may send RFE at different stages, but mostly after they received the RFE, they will adjudicate the case soon if it is adjudicatable.
