After I called once on 6/22/06. I found the update of I-485 LUD w/o the change of status. However, I think this change was more likely related to the routine case status update from CIS. Because my I-140 status was updated too on the same day, though it has been proved earlier. My friend called me that his I-485 case status updated too. But I didn't know what happened today. My PD is not current.
