Maybe Poland changed the immigration rules for Ukrainians? I know The Netherlands did. You now can get in without a visa and you can stay at least 90 days or 180 days without problems when needed. You don’t get a special refugee status other refugees get at this point. And they are preparing shelters. No idea if you are allowed to work during those days. In The Netherlands many people can speak English, specially the younger generation. So that won’t really be an issue if your English speech is decent.
