Résumé : In his Perpetual Peace Project, Kant keeps stumbling upon the same theoretical issue: what legal architecture could maintain political communities under a same authority without depriving them from their sovereignty? The answer to that question is to be found in a rather surprising place: in Kant's defence of a limited right to immigration. Kant's cosmopolitan right to hospitality is divided between an unconditional right to sojourn and the privilege of the residence. I will argue that the institutionalization of cosmopolitanism ultimately rests on a transnational communication made possible by the migrations flows and therefore requires a progressive blurring of this distinction between sojourn and residence. This paves the way to the reinterpretation of Kant's right to hospitality as the right for migrants to have access to an integration process.
