Almost 10 years ago, when Poland start to be a member of European Union, Polish people begin to going abroad llooking for employment. it was legal, and very attractive form them. Nowadays, many of them are existing in UK, not planning to coming back to Poland. On the other hand, English citizens, thanks to cheap airline tickets for Polish workers, are able to buy flights to Poland for a couple pounds. When you have never been there, you have to totally book your ticket. This country is very amazing.
