Current as of September 12 2021.
The rules for entry to Europe for U.S citizens have been updated recently. The EU has removed the U.S.A from its “safe list” and has recommended individual states restrict entry to U.S citizens due to recent spike in covid cases in the USA. The European Union has not issued a formal ban of Americans. However, it appears that unvaccinated U.S citizens may not be allowed to enter European countries unless the visit is for a specific “essential” reason as determined by the respective government.
What this means is that “fully vaccinated” U.S tourists, U.S citizens arriving from “safe” countries, and travelers arriving for urgent reasons will be allowed entry. However quarantine and testing may be required depending on the county.
General Rules for a few select countries. These rules only apply to U.S Citizens departing from the USA. For more details visit the country’s immigration or embassy websites.
Italy. All visitors are required to produce a negative PCR test taken with 72 hours of arrival. Additionally, unvaccinated visitors will be required to quarantine for 5 days. When traveling throughout Italy, the White CDC Card must be shown to board long distance trains and enter museums, concerts, stadiums, and dine indoors.
France. Americans who show proof of vaccination with the White CDC card are allowed entry to France. Testing and quarantine is not required. Non-vaccinated people can only visit for “essential travel” and must undergo testing and quarantine.
Spain. All travelers must register with the Spain Travel Health Portal. Americans who show proof of vaccination with the White CDC card are allowed entry to Spain. Non-vaccinated people can only visit for “essential travel” and must undergo testing and quarantine.
