Oh, I didn't have to go in when I renewed either. Just did it online. But Rachel, I certainly don't have a narcotics license! I had to drive to Philadelphia first time I enrolled, a good 3 hour drive each way and a full interview, he must have wondered why I'd been in Saudi Arabia. It was more than a token interview, perhaps because it had so many strange countries at the time on that passport.
Still glad I did it, not only for re-entry to the US when I travel, but now, the advantages for domestic travel as well, getting priority access through security, I just love it. And Amex pays for it.
