netherlands, denmark, maybe germany, maybe finland. i'd most rather live in the netherlands or possibly denmark, although it'd probably make more sense for me to want to live in germany or finland because i don't speak dutch or danish lmao. regardless though getting permanent residence in denmark or finland is practically a hopeless goal for a majority of people, so they're basically out of the question

i can get slovak, maybe german citizenship based on descent (i'm in the process of getting the stuff i need from the slovak government to apply for citizenship but they really take their sweet time) and i'm mostly a software guy so it'd probably make the most sense to move to one of those, however the netherlands probably holds way better opportunities for me

for most people getting into another country (especially europe) is out of the question though, you either have to have extremely marketable work experience (like 3-5 years as an engineer or developer) or you have to happen to qualify for citizenship by descent and have the birth/marriage/death/citizenship/residence documents for it (e.g. anyone who had italian citizenship since 1860, anyone who lived in an area controlled by hungary ever since hungary existed, anyone who was polish 1920 or later, anyone who was czechoslovak or german for the past century, an irish grandfather)
