"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."

That is what I, and presumably several other commentators, have been responding to.

Edit: I see that one post referred to the ETIAS initiative. But what you’re saying makes perfect sense now. I’m only talking about the visa. My apologies.
