The purpose of this article is to analyze Argentina’s migrant regularization policy implemented under the administration of Alberto Fernández, between 2019 and 2023. The proposed theoretical-ethodological approach is based on the analytical distinction of three levels: 1) legal-normative, 2) bureaucratic-administrative and 3) sociodemographic (the effects or impact of the regularization policy on the migrant population). Through a cross-referencing of primary and secondary sources, the analysis also differentiates the policies according to whether they were oriented to manage the urgency, generate compensation mechanisms or normalize and standardize the public agency. Finally, the manuscript includes a specific section that systematizes and addresses key statistical information to longitudinally measure the impact of migration regularization policies in the period under study. In the conclusions, the findings are taken up and the regularization conditions bequeathed to the next government are indicated.
