My family recently completed the application and interview process in less than 3 weeks from date of application to receiving cards in the mail. We interviewed at the Atlanta Customs office (not airport terminal location) and although it showed no appointments until about 6 weeks out, I checked periodically throughout the day for a couple of days and on a Thursday a full day of appointments opened up the the immediately following Sunday. We were able to book four appointments over two time slots and the interview process was quick and simple.
