Hi, friends,
I found a trick that you can predict your case much better than using the processing dates that are posted on USCIS website.
My case is EAD in VSC, and all cases in VSC are started with "EAC". After "EAC", the next 5 digits are for your Notice Date. E.g.,
EAC05245***** is for cases received on 09/12/05;
EAC05255***** is for cases received on 09/26/05, 10 working days after 09/12
Then randonly pick some numbers to find out the category of your case, such as
EAC0524551723 is a case of EAD, ND 09/12, AD 09/26.
What I found is that most EAD cases take only 3 to 4 weeks, but the USCIS posted processing dates are in June or July, too far away from the real processing progress.
You can use the same trick to predict when you may get your EAD, AP, etc. Good luck.....:)
