The European Union on Monday removed Israel, the United States and four other countries from its COVID-19 safe-travel list, meaning that travelers from those countries could now face increased restrictions.

Removal from the list is a non-binding recommendation, however, and the E.U.’s 27 member nations can decide individually whether to follow it. Tourists should therefore “expect a mishmash of travel rules across the continent,” AP reported.

On June 30, 2020, the European Council adopted a recommendation on the gradual lifting of the temporary restrictions on non-essential travel into the European Union. The list is reviewed and updated regularly.

Most non-E.U. visitors who are fully vaccinated are still allowed in by the bloc, though various restrictions can apply depending on the country, including quarantines and testing, according to Reuters.
