In Argentina, the National Immigration Department has the authority to remove or deport foreign nationals under Law 25,871. When an individual breaches immigration laws, the department can issue an administrative decision that cancels their residency, declares their immigration status irregular, orders their deportation, and prohibits their reentry into the country.

However, expulsions can be contested through various appeals, including reconsideration, administrative appeals, and hierarchical appeals, which can temporarily suspend the enforcement of the deportation order.

It is essential to highlight that migrants are considered vulnerable under national and international law. Human rights treaties, such as the American Convention on Human Rights, guarantee migrants the right to defense and due process during immigration procedures. These legal protections ensure access to a fair, transparent process while safeguarding their fundamental rights.
