UPDATE: Interview went fine ... no questions about countries. It was fingerprinting, and him asking how much I travel and for what purpose. I brought my drivers license (wrong address) and my voter ID card (right address). They took people in groups of 4 to watch a video then called them 1 by 1 to speak with agents. When we all 4 sat down he asked for "passports and drivers licenses... and if your address is wrong on your drivers license anything that has your correct address on it."

At the end of the interview, he told me to go to the TSA.gov site and sign up for pre check with my trusted traveler #. I can't find anywhere to log in with that on the TSA site...
