Based on the Colombian experience (2014-2018), this book presents the main challenges faced by recipient countries of migrant populations when building public policies, response institutions, and internal regulations with internal and international demands that imply the application of a human rights approach. This research was proposed within the frame of the Socio-Legal Network in 2017 and involves twenty-one Colombian universities, as well as forty-five researchers under the leadership of the Universidad del Rosario, aiming to elaborate a diagnosis that, from a national and regional perspective, gives account of what has happened in response to the rights of migrants to health, education, work, and access to justice in the last four years in Colombia. The work starts with a reflection on the role of national institutions regarding Venezuelan migration, followed by an analysis of the situation in the country’s border areas as well as response in the central zone, the Antioquia region, and the coffee-growing region (Eje Cafetero). The closing chapter examines one of the most serious problems resulting from the diagnosis: the issue of statelessness faced by thousands of children born to Venezuelan women in irregular migratory status in all regions of the country during this period.
