At this time USCIS cannot provide you with information for your case. Please contact the NCSC 1 (800) 375-5283 for additional information. what does it really mean ? My case got an RFE, converted it to premium and responded for the first RFE. Got one more RFE ..with status as Initial review for couple of days. Now, nothing is showing in the status with that message. Can anyone throw some light on it ?
