The requirement involves an online travel authorization through the European Travel Information and Authorization System, or ETIAS, and it applies to the visitors of 30 European countries. That includes popular destinations such as France, Spain, Germany, Greece, Italy, and Portugal.

Now, the system "will be ready to enter into operation in Spring 2025," said a brief announcement after a meeting of the Council of the European Union earlier this month. "The new roadmap for the delivery of the new IT architecture foresees that the Entry/Exit system will be ready to enter into operation in Autumn 2024," it also said.

In a recent update to the European Union website for ETIAS, it said that "mid-2025" is when the new travel requirements will go online. No applications are being processed or "are collected at this point," according to the website.

Multiple reports noted that the system was supposed to go into effect in 2021, but it has been postponed several times since then.
