In Chile, during the last decades, different interventions have been carried out in migration matters, in accordance with international standards. However, the securitization approach has strained the evolution between society and institutions. Since, from formal institutions, ideas are proposed in order to adapt to the phenomenon, but informal institutions have been strongly influenced by the National Security Doctrine, stressing the transition and the social disposition in the face of these changes. The present research is located in a descriptive interpretative perspective, since it aims to evaluate the influence of the National Security Doctrine in the Chilean migration policy, which is based on a qualitative analytical model, which was already focused on the case study on the city of Iquique, evidencing the asymmetric relationship that comes from the securitization approach, conditioning the citizen perception of the migrant, how this approach positioned him/her in the migration policy and the conflict between transition versus disposition. The findings suggest that the migration policy, despite its reforms, never managed to adapt to the evolution of migratory flows, due to design, sound, political and educational factors, which generated a humanitarian crisis in the north of the country.
