Due to the intensification of global migration movements, the importance of studies in the field of acculturation has been increasing. In order to develop a healthy adaptation process between the migrant community and the host society, it is especially necessary to conduct studies on the acculturation processes of young migrants. Exploring the acculturation orientation of migrant students in Turkey, one of the leading countries experiencing the migration movements intensively, this study collected data from a total of 110 migrant students, 69 females and 41 males. "Vancouver Index of Acculturation", "Revised Social Contact Scale", "Multidimensional Scale of Perceived Social Support", "Turkish Proficiency Level Questionnaire" and "Personal Information Form" were employed as data collection tools. Multiple linear regression analysis was used to analyze the data. The analyses results revealed that the level of perceived social support of migrant students from their families and the quality of social contact significantly predicted their heritage culture orientation and explained 18% of them. In addition, the quantity of migrant students' social contact and the quality of social contact significantly predicted their mainstream culture orientation and explained 25% of them. As a result, the present study put forth that in order to support the heritage culture orientation of migrant students, the perceived social support from the family should be improved, and the quantity and quality of social contact should be increased to reinforce their mainstream culture orientation and to facilitate the acculturation processes.
