I mentioned this over in the Trip Reports section and thought I'd post it here too in case somebody missed it.
My grandson and I returned from Italy and Germany last week. Chicago was our Port of Entry.
We traveled light, with only one Rick Steves backpack carry-on for each of us. We discovered another excellent reason to travel light. US Customs and Border Patrol has just initiated a "One-Stop" process for travelers arriving with no checked luggage.
On my trip last August, despite having only the carry-on bag, I was stuck in the Immigration and Customs lines at O'Hare for the better part of an hour. No fun having just stepped off a ten-hour flight. This time at the same airport, signs directed arriving carry-on-only passengers to a different area. We were second or third in line at the counter. When it was our turn, we presented our Customs declaration form, the officer stamped it, and we were on our way in less than a minute.
What a nice surprise!
