US citizens visiting parts of Europe will need authorization from the European Union come 2021.The EU announced last year it was creating a European Travel Information and Authorization System, or ETIAS, that will require "pre-travel screening for security and migration risks of travellers benefiting from visa-free access to the Schengen area."The Schengen Area is a zone of 26 European countries that do not have internal borders and allow people to move between them freely, including countries such as Spain, France, Greece, Germany, Italy and Poland. Currently, US citizens can travel to Europe for up to 90 days without any sort of travel authorization. ETIAS will change that.
