Yes my family explained to me the difficulties in finding a job here but i decided to give it a shot anyway i love the place and you only live once.
Lesko isn't particularly wealthy in that region (it's not as bad as some other areas, but it has those rather poor housing estates on the road to Cisna) - and employment is hard to come by for locals, let alone foreigners who don't speak the language.
What kind of business do you think would be viable here?
In Lesko, very little - it's simply not a tourist destination as everyone is driving through.
If I were in your shoes, I'd be looking at starting a business in Cisna. It's the most well-run out of all the villages there, and has the most potential to expand further. But you'll need significant capital to even start there.
More to the point, on what basis are you staying in Poland? Do you have a valid residence permit, or an EU passport?
