My employer had filed for H1b amendment under normal processing in Oct 2015. On 26 Feb RFE was raised for same. We prepared documents and sent to attorney. Before attorney filed response we requested to upgrade case to Premium processing. On 21 April status got updated to my case was received and receipt notice was emailed. Immediately next day status got updated to RFE issued. My attorney says they are yet to file response for previous RFE.
So this new RFE would be just because case got updated to premium processing or USCIS might have asked for note documents?
