回複：I485 LUD

I had 2 non-FP related LUDs last week too, similar to yours. Went to infopass today. Was told that somebody reviewed my case last week. I guess that's the cause of the LUDs. I've also heard though that LUD might be system update that has nothing to do with the case. You may call your service center and try to talk to an IO and see if they know more.

Anyway, it looks like a pretty positive sign. Good luck to you!
