thank you nervewreck for your answer,
to educate me well can you correct me if I am wrong !
FD (Filing Date) = Date when I-140 application is been received at INS center
RD (Reciet Date) = Date when INS accepts the application & gives LIN/SRC no.
LUD (Last Updated Date) = Date when I-140 case status was last updated.
AD (Approval Date) = Date when I-140 case is Approved by INS.
PD (Priority Date) = ???
# Does it make difference is GC process is done with or without RIR, if yes then can you tell me what is the difference ?
# I have choosen consuler processing after I-140 [EB2 Category], so I will have to go for cousuler processing right after I-140 is approved ?
I really appreciate you help.
thank you for your time.
