The thesis investigates the potential adoption of language and knowledge of society requirements for citizenship in Sweden. With thorough review of the language requirements context and the changing political discourse around citizenship requirements the thesis tries to explore the implications of this policy with particular focus on refugees and low literacy immigrants. Based on Bosswick’s and Heckman’s social integration theory the thesis tackles the impact of language requirements on integration outcomes based on four dimensions: structural, cultural, interactive and on  the dimension of identification. Moreover, by employing a qualitative research design that includes both expert interviews and document analysis the thesis aims to explore broader insights of the requirements' effect on the process of integration. Findings of this study indicate that language proficiency is crucial for integration but making language a requirement for citizenship may lead to barriers for vulnerable groups if necessary measures are not taken. Therefore, the study wraps up with the suggestion that if such policy is to be implemented adequate flexible assessment processes and resourceful support system must be considered so that the policy is implemented fairly for everyone.
