Hi! We didn't need to show anything at the time we left (November 2022). No transit visas were necessary for us (we hold US passports). Since this summer, Paris is hosting the Olympics, I would suggest to keep checking their government or airport websites to see if there's any changes or temporary transit requirements. Have a fun trip! Safe travels
@@Ticket2Anywhere Thanks so much for the information. However, I will like to knw if those countries that are not require transit visa, it is possible that they exit the airport doing their layover?
