Pardon my silly questions, it's the third time I'm logging on to this web site and I'm still confused with all the abbreviations. My guess is
EAD- is obvious
AP- advanced parole
LUD? no idea what is this, and how do you find it = IT IS last updated date. You find this if you register with the USCIS site to track your cases EAD, I-140 , AP, I-485. Case Status Portfolio with Updates via Email is where you register.You enter in your receipt numbers and you can get it to email you when there is an approval on your case or when they are doing internal processing.

* 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.
FP- finger printing
ND- notice date
RD- receipt date
AD- no idea again what it is =APPROVAL DATE
what is the difference between ND and RD = Notice date is the date USCIS receives the application, Notice date=when they generate you receipts.
Thanks in advance
Keepthe hope
