Hi, for those who received rfpr fee, mr and pcc requests, I suggest that you submit whatever documents you have first before the deadline and include the courier confirmation from fedex or whoever else you use as well as writing a letter to the visa office requesting time extension. When I found out my fingerprints were rejected in apr, I sent 4 more sets of fingerprints to fbi and include the courier receipt confirmation as well as the rejection letters and raise cse to the visa office. I received a reply within 2 business days to keep them updated. I am hoping to receive good news soon regarding my april 28th fingerprint submission. In the meantime, I have also requested state pcc just in case pending from California.
Good luck to everyone!
