The perception of migratory processes as a national security issue, especially irregular immigration, has led to governments adopting regulations that disrespect fundamental rights and guarantees. Identified and classified as the others or enemies who threaten social order, immigrants in condition of migratory irregularity are transformed into the targets of a criminalizing discourse, not only in public and political debates, but also in legislation. The preventive reinforcement of security measures in American and European legislation after the terrorist attacks in 2001 in the United States, gave rise to the phenomenon of convergence between Criminal Law and Immigration Law, with the emergence of the term Crimigration. In this context, this paper aims to study the immigration security relationship, considering first how the concept of Criminal Law of the enemy and the emergence of the global perception of the immigrant as the other strongly influenced the creation of American and European legislation aimed to prevent illegal immigration. Furthermore, the present research analyzes how Chile is not disconnected from this phenomenon, but like other countries, has adopted the same logic mentioned above in its new migration law. This new law, passed in 2021, although considered on paper an advance in the fulfillment of international standards for protection of rights, in reality it perpetuates conditions of exclusion for migrants, with a strong inclination towards the closing of borders, based on the criminalization of immigration.
