I currently make about 80k US (could be a little over 100k if it wasn't for the school obligations). I work in IT and hope to keep it that way in Europe. If I can make at least 50k US in Poland I would love to stay there and not go anywhere else.
I know a few foreigners working in poland in IT. Salaries seem to vary considerably though but some of these guys are doing OK. However, you can forget about making the equivalent of 80-100K USD in poland!
Personally if i were in your position and given the state of the economy right now, I would remain in the US.
But I'm also a polish american living in poland so i kinda understand why you may want to try living in PL.
Life in the states seems a bit too easy and predictable to me right now. I’m looking for a challenge and excitement.
hehe if a more difficult life is what you're looking for, then poland is a suitable place for you:)
