ETIAS is a travel authorisation for visa-free visitors to Europe. Travellers on an Indian passport need a Schengen visa instead, and do not need ETIAS.
Passport stamps are giving way to a digital record of your fingerprints and photo when you enter or leave the Schengen area. Here is what that means for Indian travellers.
The UK’s electronic travel authorisation is only for nationalities that can visit without a visa. India is not on that list, so a UK visa is still what you apply for.
