After a year, Europe welcomes travellers back in the hopes of reviving tourism.

After more than a year of Covid-imposed limitations, Europe is reopening to Americans and other visitors in the hopes of drawing tourists - and their cash - back to the continent's trattorias, landscapes, and cultural treasures. Travelers, on the other hand, will require patience to figure out who is permitted to enter which country, how, and when.

Tourists will discover a patchwork of systems rather than a single border-free leisure zone as the European Union's doors reopen one by one to the outside world for the first time since March 2020, because national governments have resisted giving control over their borders amid the pandemic. And, post-Brexit, the United Kingdom is going its own way. Meanwhile, the warm welcome isn't always reciprocated. Non-Americans are still primarily barred from entering the United States.

The EU's 27 member states lack a common Covid tourism or border policy, but have been working on a shared digital travel certificate for persons who have been vaccinated, tested, or recovered from the virus for months. The measure was approved by EU parliamentarians on Wednesday. The free certificates, which will include a QR code with sophisticated security features, will allow people to travel between European nations without being quarantined or having to undergo additional coronavirus testing. Spain, Germany, Greece, Bulgaria, Croatia, the Czech Republic, Denmark, and Poland are among the EU countries that have previously implemented the system.The remainder of the country is slated to start using it on July 1st. It is primarily intended for EU citizens, but it is possible for Americans and others to receive the certificate if they can persuade officials in the EU country they are visiting that they are eligible. Furthermore, the absence of an established vaccine certification mechanism in the United States may exacerbate the situation.
