I am currently travelling to the US and I have a EU passport. I also have a valid ESTA document. I fly from Germany to Chicago and continue with a domestic connection flight.
Chicago Airport provides information for international travellers:*
If you are traveling from a country that requires a visa- or if you are a first time ESTA passenger- you must wait in line at immigration.
If you are a permanent U.S. or Canadian resident, have Global Entry, or are a repeat traveler from a country with a visa waiver, you may skip the line at immigration and use the Global Entry or Automatic Passport Control kiosks to the left instead.
I was in the US three years ago, also with a ESTA document. The first ESTA of course expired, so I got a new one. Am I a repeat traveller by the definition above or not? I ask because I want to know if I can "skip the line at immigration and use the Global Entry or Automatic Passport Control kiosks to the left instead."
* This link became invalid some time before July 2017. The information is now at Chicago O'Hare: Automated Passport Control and no longer uses the form of words present in the question.
