Can add. Ukrainian citizens can enter EU countries without a visa on a Ukrainian passport. Russians are required to have a passport, as well as visas. Getting a visa for the first time, and even more so, in the last 2 years is very difficult. For those who had a multi-year visa, it is much easier to enter the Schengen countries. But for 2 years already, the coronavirus has been giving a pass only to the closest relatives (spouses, children / parents), to some countries, and to couples in love has given the opportunity to reunite. And it is even more difficult for ordinary people to get into the UK.
