The USA closed the borders to Europeans at the beginning of the Corona pandemic. Now the end of the travel ban has been announced by the American administration. From November, fully vaccinated people will be allowed to enter the country again. Despite the good news from the announcement, questions remain about the exact implementation.
According to information from the US Embassy in Berlin as well as the US Consulate in Frankfurt, from now on (retroactively from July 5, 2021) the NIE certificate is valid for 12 months and entitles to multiple entries within this period.
