Ok, what\'s the point? It says:
What is the order of I-485 processing?
The I-485 application is supposed to be processed based on the order of the application receipt, that is by the RD or ND. Of course the PD should be current for adjudication. But in reality it doesn\'t just happen strictly on the order of RD! This may be due to RFE, FP redo, INS clerical error, etc.
Doesn\'t seem to be any huge revelation and in fact it seems counter to what you\'ve been saying. You said that they were tracking in order of PD but the source that you cite says RD. My understanding was always RD as long as the PD is current.
