We're now seriously considering getting over to Europe before the transfer of power. I'd give it maybe 10% chance now but it's certainly something we've begun to talk about as of this morning
If you're serious, then before you move to Serbia and get your ass beaten by a random Orthodox incensed you got blind drunk on palinka with a Muslim before throwing rotten fruit at a Catholic: there are many places that'd hire you as an English teacher and you don't even need a teaching degree in a private language school. Your chances of getting hired would probably be higher outside Warsaw, but it's a stable line of work that'd open you a channel for work visa. There are also higher learning institutions opening a) new medical schools, b) degrees done in English. MPH would certainly suffice for research/teaching assistant job at many places. Maybe not ideal, but beggars can be choosers until they get a nice car or something along those lines. EDIT/BTW: These are just my 'shots from the hip' as far as jobs go, I'm sure there's a lot more. You could probably work as an analyst in quite a few places. My, uch, 'enemy with dubious benefits' basically did your programming/modelling class for a living through EY or something like that. Here are job application sites (I think they have English option?): https://www.pracuj.pl/ https://www.aplikuj.pl/ https://www.olx.pl/praca/ Public institutions often don't use those and assume you'd navigate their site, so if you'd need my help, you know how to get ahold of me.
You've probably looked it over more than me @ Europe, but my Ukraine friend says the easiest way is to take a stint in Serbia or Kazakhstan and then transfer from there to Western Europe a few years later
