This chapter discusses the impact of EU immigration legislation and policy on Swedish policy and politics.1 Since domestic impact is perceived from the perspective of supranational legislation and policies, it makes sense to approach it primarily in terms of an adaptation pressure. This pressure is more extensive the larger the misfit between EU and Swedish legislation and policy, and it cuts deeper the more it entails changes to politics, such as policy processes, public discourse and conflicts between political actors (see Börzel and Risse 2003; Radaelli 2003; Risse et al. 2003).
