Abstract
While the concepts of heterochrony and heterotopia forged by Michel Foucault have an explanatory scope that goes far beyond their original one, their contributions to the field of mobility and migration are examined in this paper through narratives of absence. It will be a question of grasping the way in which these stories put into perspective the experience of absence, as a separate space and time, due to the uncertainty that weighs over a condition of becoming a migrant. In this article will see through three illustrative accounts of situations of absence that they open up broader questions about a missing presence and the reasons behind it.
