What do the EU rules mean for Americans traveling to Europe?

A lot more red tape, uncertainty and research, that’s for sure.

Ultimately it means that traveling to European countries is likely to become harder for Americans in the weeks ahead, although not necessarily impossible.

As the rules change, it’s up to individual travelers to check their eligibility to travel. Although airlines may also do checks before departure, they won’t need to in order to sell tickets.

It’s worth checking CNN Travel’s Unlocking the World guides for up to date info where relevant or the US embassy in the country of destination. And then keep checking as the rules can change with just a couple of days’ notice.
