Abstract. Accelerated and increasingly complex patterns of international migration are correlated with the emergence of various types of transnational families and an ever-rising number of culturally and ethnically mixed couples. Once a typical emigration country, Turkey has recently been established as a transit and receiving society, where numerous Europeans settle due to emotional ties with Turkish citizens . This paper is based on a qualitative study of 10 mixed European-Turkish families based in Istanbul, carried out through in-depth interviews. The paper is divided into three parts. First, it examines the social characteristics of the research participants . Second, it analyses the reactions of family and friends to the mixed relationship . Third, it discusses four adaptation strategies of foreign partners to Turkish society -namely, integration, assimilation, separation, and marginalization .
