lc2003,
Yes, gc0902 is correct, but ic2003, can you be more specific about your details of your case like filing date, FP date, EAD date, AP date, etc? We can't tell if you don't tell us your details.
From my opinion, it looks like officers are checking your case. If you are done all FPs or you are done applying for renewal EAD or applying for AP, LUD will update each when they check your 485 case. if your RD/ND date is on the list of processing times, it is possible that they are adjucating your case. (approval may be possible very soon
)
Three theories about LUD changes are:
1) When officer receives your EAD application or your renewal application or AP application, they wants to know if you are still in 485 process so they have to find your 485 case on their computer system. When they found your case number on the system,
it automatically trigger updating LUD and they proceed to approve your EAD or AP.
2) if you already submitted EAD or AP and you got EAD and AP but your 485 is still pending, it means they are opening your case and reviewing your case.
It trigger updating LUD. It means it is up to officers to make decisions to approve your case or need more information from you as a RFE or to deny your case.
3) Randomly, officers open your case and check RD/ND date. If RD/ND is not on the list of current processing times, they put them back.
It triggers updating LUD.
That's what I think. I am neither a lawyer or an officer.
Good luck.
