I had actually posted on a different post, thinking that I had done it on this one. So here are the details:
At my INFOPASS appointment, I was told by the IO that my file did not arrive in time for the 09/18/2009 interview date and hence the descheduling notice was automatically sent out.
He found out that I was already assigned a new date (11/10/2009) and I recieved that letter in a weeks time.
06/30/09: N-400 Received at LEWISVILLE, TX
06/30/09: Priority Date
07/21/09: Fingerprints Done (Scheduled)
08/14/09: Yellow Notice Received
09/10/09: Interview deschedule notice
09/17/09: Informed of new ID (INFOPASS)
09/18/09: Interview Date (Descheduled)
11/10/09: Rescheduled Interview Date
Thanks for sharing, looks like I need an infopass to find out my result...
