Both myself and my wife applied for GE on 9/25/17. We're both UK citizens and got Conditional Approval yesterday (10/10/17) just over two weeks. We're travelling through Arizona in November so were looking for Interviews in either Phoenix or Tucson. Phoenix had limited availability but Tucson had wide open availability 5 weeks out. If you don't mind driving a bit further, don't forget the Center in Nogales; they appear to have 3 interviews per time slot (81 per day).
