I think I figured out what happened (maybe)
The reply to my fax inquiry confirmed the existence of the
application. The response also indicated the receipt of the change of address request on 6/26.
EAD receipt # = 03-168-5ABCD (May 12)
Out of curiousity I checked
WAC # = 03-200-5ABCD (Jun 26)
Lo and Behold! This application is an I-765 application as well.
So, some idiot in BCIS took my change-of-address form and
screwed up the receipt # of my I-765?
Coincidence?? Perhaps..
I filed for AP and EAD for myself and spouse at the same time.
All WAC-03-168 numbers have corresponding WAC-03-200
numbers. Except, one I-131 receipt has been converted to
I-765. The AOS receipt numbers correspond to a I-765
receipt number and OS155A approval (whatever that is).
I'm still going to try for iEAD on 11/8 though...
