With a PCR test Ukraine has been open to US Tourism since at least February, maybe earlier but that's when I started tracking it. Although the borders have been open there has been a short lockdown in the major cities. Most of those were lifted today.

The six-week lockdown ends on May 1, in time for Easter and traditional May holidays. “The situation in Kyiv improved by every measure,” Health Minister Maksym Stepanov said on April 27. It’s not just Kyiv. Ukraine is beginning to exit the third wave of the pandemic, according to Stepanov. Yet another reason for optimism came from a spike in COVID 19 vaccination. Restrictions lifted
The end of the lockdown lifts almost all quarantine restrictions in Kyiv: Restaurants and cafes open up, but have to close at midnight; stores, malls, cinemas and gyms reopen; public transport is accessible to everyone; schools and kindergartens reopen.
Some restrictions remain. Mass gatherings indoors are limited to give each visitor at least four square meters of space. Mask wearing remains mandatory in all public spaces and public transport.
As Kyiv eases restrictions, nine Ukrainian regions remain under lockdown: Kyiv Oblast, Zhytomyr Oblast, Zaporizhia Oblast, Mykolaiv Oblast, Poltava Oblast, Sumy Oblast, Kharkiv Oblast, Khmelnytsky Oblast and Chernihiv Oblast.
The lockdowns in big cities, including Odesa and Lviv, are being lifted as Ukraine goes into a holiday-heavy period. May 1 and May 9 are official holidays, and Orthodox Easter is celebrated on May 2. Ukrainians will have two long weekends: May 1–4 and May 8–10.
