The decision about emigration for economic reasons, including emigration to Ireland, after Poland joining the European Union, has been the object of research interests of a number of fields of knowledge. Sometimes, a tempting vision of improving Polish people’s own economic status makes them decide to leave the homeland without any knowledge about the culture of the adopted society. The article is focused on the analysis of the language competence of Polish grammar school students in Ireland. There are presented weaknesses and strategies for surviving in the new environment without language skills and its influence on adaptation to school and life in Ireland. The article is supported by the research conducted in Irish grammar schools and Polish weekend schools in Ireland (2010–2011).
