US citizens will need a visa to visit Europe starting in 2021
The article mixes two seaparate issues:- EU is introducing ETIAS, an electronic authorisation system which is pretty much modeled after the US ESTA system (used by visa-free nationals). It will apply to all countries which currently enjoy the visa-free regime with the EU and that includes USA. So, technically it is not a visa, but your details will be pre-checked and it will cost €7 (compared to $14 for US ESTA). Ironically, after Brexit, this requirement will also apply to UK.- There is a separate dispute between EU and US, because US imposes visas on five EU states (Bulgaria, Croatia, Poland, Romania and Cyprus). According the EU law, all EU countries should be treated equally or otherwise reciprocal measures should apply. There have been calls within the EU to respond tit for tat and impose EU visas on US citizens, if the issue does not get resolved soon.As an EU citizen, I can just add that I support both initiatives.
