High Quality Content by WIKIPEDIA articles! Immigration to Colombia has been historically low when compared to similar countries such as Venezuela, due to economic, social, and security issues linked mainly to the Colombian armed conflict. Colombia inherited from the Spanish Empire harsh rules against immigration, first in the Viceroyalty of New Granada and later in the Colombian Republic. The Constituent Assembly of Colombia and the subsequent reforms to the national constitution were much more open to the immigrants and the economic aperture. However naturalization of foreigners, with the exception of those children of Colombians born abroad, is still very difficult to acquire due to paperwork and bureaucracy. Immigration in Colombia is managed by the "Departamento Administrativo de Seguridad" (DAS).
