How can I apply for the newly required "visa" to European countries? I have read brief articles about the requirement, but they do not direct the reader to the application.
Presumably you are referring to ETIAS
Ain't happening til 2025, at the earliest
As Joe32F said its not happening any time soon and the best advice is to keep track of the official EU websites --
https://travel-europe.europa.eu/index_en
https://travel-europe.europa.eu/etias_en
You do realize that the visa will not be a requirement of ALL European countries. Just some.
nothing to be worried about
