Argentina's President Javier Milei has dismantled the country's two-decade-old framework of rights for foreign nationals, replacing it with a new migration regime that treats immigration primarily as a security concern, mirroring policies pursued by Donald Trump in the United States. The overhaul marks a sharp break from the relatively open migration system Argentina had maintained since the early 2000s. The shift signals a broader ideological realignment under Milei's far-right administration, with significant implications for the millions of migrants — many from neighbouring Latin American countries — who have long viewed Argentina as a destination offering legal protections and a path to residency.
