Integration is a term that can be defined in different ways. In this study I investigate how the integration process for unaccompanied refugee children looks from the professional's work with unaccompanied refugee children. By semi-structured interviews with three social secretaries from two different communities and three interviews with three treatment assistants from two different homes for care and living have I investigated how they work with the integration process of unaccompanied refugee children. I have also investigated what social problems they run into and how they are managed and also what challenges the professionals face in their work with unaccompanied refugee children. In this study I concluded that the integration of the unaccompanied refugee children is affected by their well-being, activities, and their degree of understanding of their situation. The study shows that social problems, such as mental illness and criminality are usual anticipation and it is something that social workers are actively working with. The study also shows that high employee turnover and laws, rules and structures affect the professional's work with the young people, but also their collaboration in itself.
