Humanitarian organisations and migrant shelters have been the main advocates against the criminalisation of migrants by state authorities in Mexico. Some of these organisations have sought to support migrants trying to reach the US-Mexico border, yet within their day-to-day activities, they also cooperate with governmental institutions which suggests more complex functions.

This paper argues that NGOs engage in practices of screening, doubting and policing of migrants from the Global South that do not align with their intention to safeguard them. I also explore instances of punishment, time constriction and paternalism used to discipline racialised migrants. I examine colonial logic that persist in these places, the racialisation and subordination of Central American migrants, the influence of the UNHCR, that ultimately lead to the dehumanisation of individuals
