Migration outflow from Poland observed since 2004, both temporary and settlement, is one of the biggest waves of migration Poland has experienced throughout the postwar period. Since 2004 destination countries for Polish migrants have also changed. Before accession to the EU, Germany was the dominant first choice, with the United States in the second place. Following the enlargement of the European Union and opening of labor markets to Poles by some EU-15 economies, the United Kingdom found itself a strong leader among destination countries for Polish migrants, whereas the U.S. dropped to the fifth place. The results presented below relate to labor migration from Poland to the UK. The research presented here is the first quantitative research conducted in the UK by researchers from Poland on the legally working community. It took place in London in autumn 2007. The questionnaire was used on a purposive sample of 636 respondents.
