Dallas Office.
I had an interview scheduled last May (6 months to the day after FP), but about a week before the interview, they realized that my file had not yet arrived, so they descheduled my interview (my wife had hers, and is a USC now). Apparently everything is fine with my file -- the Dallas DO apparently just wants to drive me crazy.
Here is my timeline. I hope yours works out better:
