I C. Thanks for the info. From what I gather, the LUD really doesn't have much bearing on how close your case is to being approved. I have been checking on my EAD renewal night and day on the USCIS website and this is the message that is displayed at the bottom after I login to check my status.
"Note on "Last Updated" date:
Your case may have a new "Last Updated" date and you may receive an Email Notification of your case being updated, without the status of the case changing. This is due to internal USCIS processing being performed on your Case. This will be reflected in the "Last Updated" date, but may not result in a different status message. "
Not sure how much that helps you. Good luck.
