For many years , Poland has been one of the largest sending areas in Central and Eastern Europe and a vast reservoir of labor for many countries in Western Europe and North America, when Poland officially became a member of the European Union in May 2004, only three EU Member States immediately opened their labor markets to nationals of Poland and the seven other Eastern European accession states: the United Kingdom, Ireland, and Sweden. By the end of 2006, Polish citizens could also freely work in Finland, Greece, Italy, Portugal, and Spain. My research are connected to teenagers and young people who are working abroad. I am wondering if they improve theirs life thanks to emigration works. What emigration means to them? Are they happy? How often the visit Poland, and family who is living in Poland? What kind of job are they doing? And is it connected to their education? Why the couldn’t find a job in Poland? Knowledge transfer between countries is very important think - on the other hand, the loss of the best and brightest participants in the work force to developed countries, commonly known as the “brain drain”, may have adverse effects on source economies. In view of circular migration, the resultant transfer of human capital and knowledge represents a “brain circulation” between the host country and the country of emigration. We can say that this is “brain waste” if it is about Polish, because Polish workers are working, for example in Ireland as a kitchen porters or housekeepers even if they are masters of economics or for example mathematics. In general research says that young Polish have new better life. They say that they finally haven’t financial problems. They are traveling around the world, meeting interesting places, people and cultures, and they can afford for everything. The financial, economic reasons are the most important for them, but on the other hand thanks to migration young polish migrants believe that world is not as bad as they were thinking, that they can more, and that their life is in theirs hands.
