Original report: The European Union announced Friday that American tourists will be required to complete an application and pay a small fee through the European Travel Information and Authorization System -- known as ETIAS -- to visit the 26 European countries that allow border-free travel, The Hill reported.
Those countries include France, Germany, Greece, Italy and Poland, CNN reported. Under current rules, U.S. citizens can travel to Europe and stay there for up to 90 days without a visa.
Minors will still just need their normal passports to travel. The ETIAS will be valid for three years, according to the European Union.
U.S. travelers will not require a prior permit to visit the United Kingdom, The Hill reported.
