Where have you got that information? That's nonsense!
No, when I was in a small village near to Czestochowa, the English Language teacher was a Pole, who did not even have a First Certificate. A few years ago now mind you, maybe they have tightened things up since? I was also in a place called Krasnik and I visited a local school where the shortage of English Language teachers in the State School System was so acute, that they were hiring young Ukrainian girls from Kiyev to fill the places. I know because I myself was there in the school, I met the teachers and I met the children and I met the School Head. Do not say that I am talking crap-I know Poland very well indeed and in my time I have been almost everywhere. In fact, I have probably seen more of Poland than a lot of Polish people living in their own country.
miot is talking crap all the time, so that's not surprising.
Yes, I am talking crap-to me it nice!
non EU workers... I don't know details as I'm Polish in Poland... but If some company has a serious reason to hire someone from outside EU then It's rather a matter of paper work.
I think that Austrlaia, New Zealand, Canada, the U.S.A. and Ireland would all count as 'native speakers'. It might take a little longer to get the visa though. Mind you, if I was from Australia I would go to somewhere like South Korea and earn twice the money for doing half the traveling.
