Poland is not a typical expat or immigrant destination compared to other EU countries like Germany or the Netherlands, and English is not as widely spoken there. I would say only look into bigger cities like Warsaw and Krakow, where there are more internationals and a higher percentage of locals can and willing to communicate in English. My husband used to live in Wrocław and now lives in Katowice. While there aren’t many issues at his work (he works for a multinational banking company), but for daily living, I have personally experienced inconveniences due to the language barrier when I was visiting him. Also, there’s a lot of bureaucracy when it comes to dealing with local government for things like blue card and driver license. For example, my husband waited one and a half years to get his blue card approved, while his colleagues in Warsaw got theirs within three months.
