Hi Lilly-- Dont forget to invite us to party once you get your card. however, i am sure you have 4 different receipts for I-140, 485, 765 and Advanced parole 131. Since you already submitted your RFE for I-140 and was received by USCIS, your nexr RFE is under I-140 or 485? if its for the I-140, they might require additional docs or NOID previously said by Harris. Either way, check with your attorney for the RFE see what they asking for. It is very unsual to send second RFE on I-140 for the same case, however its possible for EB1 if its under NIW filing. IF your RFE is for I-485, then there is no need to worry, they might be asking for your Medical/Birth Certificate, Employment verifation etc. which you provide easily. since the bispecilization started from April 1st, your case should have been filed at the NSC and later forwarded to TSC (sister center). Usually NSC sends EB1 as well as EB2 case to TSC for adjudications and TSC much for flexible than NSC... Is your I-485 receipt start with SRC also... if it does, then your case is in TX Serv. Ctr., share with us when you get to read to your second RFE. good luck
