I have exactly the same LUD 4 days in a row

My EB2 based I485 filed at TSC in July 2006. I called to initiate an inquiry to status 30 days ago. I saw LUD on 3/21,3/22,3/23,3/24. My guess is that someone has reviewed my case, but I doubt the most I can receive in the near future is a letter stating that additional time is needed to process the case...

Don't get too excited. It may mean nothing.
