To understand how the migrations have been Consolidated as a security problem even if traditionally they were not identifying as a matter in this field, it is important to realize a brief review of the historical development of the migrations in United Kingdom; this with the aim to raise a basic context to understand the securitization of the migratory policies in the development of this work across the following chapters. Many have been the studies and surveys realized by organizations of the United Kingdom that have sought to demonstrate the panorama of the negative image that has been constructed from the population of the United Kingdom opposite to the population of migrants that enters to his territory. An example of this is the report realized by the Observatory of Migration of the University of Oxford on the public opinion about the immigration, in which of general form they expressed the need to do more restrictive policies opposite to the revenue of migrants to his State. Being this so relevant problem at present, this work tries to determine how has the configuration of the social perceptions opposite to the migrations like a threat for the state safety of the United Kingdom carried a process of securitization of the migratory politics between 2007-2015? this bearing in mind that the migrations every time have been assumed as a forceful threat to the national security and of his population. This analysis will be done by means of a review of political speeches on migration in United Kingdom in the period understood between 2007-2015, established as a period of increase in the migratory controls and of evident debate between the limitations to migrations and the opening as a prop for the integration in a forceful more included international system.
