Restricting Immigration from Southern Countries Under Trump: Strategic Continuity in US Foreign Policy, Geopolitical Reconfiguration of Security, and a Normative Crisis in Human Rights

This article examines Donald J. Trump's restrictive migration policy towards countries in the Global South, questioning its significance: is it a radical break with American migration tradition or a strategic continuation of geopolitical logic, security imperatives and human rights concerns? Through an analytical and methodological approach combining geopolitics, international law and normative analysis, the study explores the historical context of American immigration, the genesis of restrictive measures (executive orders, travel bans, suspension of protection and visa programmes) and the justifications put forward by the Trump administration: national security, sovereignty and cultural preservation.
