We never know for what reason the LUD changes.In my case I got EAD/AP renewal couple of weeks back but there is no LUD change.
One more thing ,I have seen some guys saying their I140 is pending for "Name Check Pending".
My I485 on line message says "the results of your fingerprint review for your I485 Application to Register Permanent Residence or to Adjust Status were received, and processing has resumed on your case. We will mail you a notice if further action is needed, or when a decision is made"
Does the above message means any thing for "Name Check" Done .
