I did the interview in Houston in November. Everything on schedule. There were 4 of us scheduled at the same. Watched a short video on how kiosk works, were fingerprinted and had photo taken. Takes place in terminal E. If you aren't flying internationally your only problem might be getting to and from terminal E (C & D in same location). Houston isn't the easiest places to change terminals. The good news is that the approval is lightening fast. Had my email by the time I arrived home (about an hour drive). And card arrived in mail 4 days later. MY bad news is that my fingerprints didn't take, even after 4 tries. TSA overrides this but it means I will always get an error message when using the system and need to see an agent. I can still go to the front of the line. They said this happens with people that have worked with paper most of their life. I was a librarian but they mentioned CPA's fingers are usually the worst. Also, you only have 30 days to do your interview once your application has been approved, so try to time it accordingly. Wishing everyone good ridges on their fingers.
