In the context of the evidence presented in both the collected scholarship under review and other select works, this article asks if and to what extent migration-related issues have been securitized in Europe and the United States. In addressing these questions it executes three tasks. First, it critically assesses the four major dimensions across which contemporary immigration purportedly is securitized: on one side, rhetorically addressing immigration-related issues through political elite discourse, public opinion, and the mass media; and on the other, the policy processes through which immigration is securitized. Second, this article identifies the strengths and weaknesses of securitization theory as it has been applied to immigration. Finally, it draws mostly negative conclusions about the veracity of the central claims of the securitization of immigration literature and, specifically, its causal story.
