This bachelor's thesis is a qualitative exploratory study. The goal of this research is to learn more about the social integration of Nigerian immigrants in Malmo, Sweden. The study focuses on language because many prior studies have found it to be an important factor in social integration. Although there is a considerable body of studies on how language influences immigrant integration, most studies focus on the host society's perspective. There is less research on how immigrants themselves evaluate the function of language in their social integration. The four dimensions of the social integration theoretical framework proposed by Bosswick and Heckmann (2006) were used to explore how Nigerian immigrants in Malmo, Sweden, perceive language as shaping their social integration in their host country. Their perceptions of these social integration dimensions will aid in understanding how language affects their integration into Swedish society in Malmo. The information was gathered from fifteen Nigerian immigrants in semi-structured interviews. The findings reveal that participants value language in varying ways across the many theoretical dimensions of social integration.
