In this diploma paper I deal with the problem of intergenerational transmission of the source language and culture in the first and second generation immigrants from areas of the former Yugoslavia, which ranks members of Albanians, Bosnians, Croats, Macedonians and Serbs. At the same time I describe the characteristics or differences between the two target groups in the field of socialization, creating their identity, community involvement and the acquisition of the mother tongue and the language of the environment. In the empirical part I present personal stories of six interviewed immigrants of both generations who have presented their efforts to transfer their first/mother language and culture (of their parents) to their progeny. The results have shown that the conservation of cultural heritage and the original language requires contacts with the source/first country, although people tend to depart from each other through a long period of staying in the majority culture. In mainstream society it is impossible to maintain their original culture and language without interlocking and creating a new "mixed" cultures and new "in-between" languages.
