In mid-to-late 2023, U.S. citizens and nationals of over 60 other countries will need an electronic travel authorization to visit much of Europe. Travelers to any Schengen-zone country will have to register with a European Travel Information and Authorization System (ETIAS).

In 2023, European entry requirements were characterized by a return to pre-pandemic norms combined with the final preparations for new digital border systems. For travelers from visa-exempt countries (like the U.S., Canada, or the UK), the primary requirement was a valid passport with at least three to six months of validity remaining beyond the intended stay. Most travelers were permitted to stay for up to 90 days within a 180-day period for tourism or business under the Schengen Area rules. While the widely discussed ETIAS (European Travel Information and Authorisation System) was originally slated for 2023, its implementation was officially delayed, meaning travelers did not yet need to apply for the digital authorization or pay the associated €7 fee during that year. Additionally, by 2023, almost all European nations had completely lifted their COVID-19 entry restrictions, including the need for vaccination certificates, recovery proof, or negative test results. However, travelers were still advised to carry proof of travel insurance and evidence of sufficient financial means, as border guards retained the right to request these documents upon arrival to ensure visitors could support themselves during their stay.
