This work investigates how the governance of human mobility is increasingly fragmented across multiple institutional layers, from local municipalities to global international organizations. Rahel Kunz, an expert in international relations and political sociology, examines the complex interplay between state policies, non-governmental actors, and supranational frameworks. By analyzing the shifting landscape of border control and migrant rights, the author argues that traditional state-centric models of migration management are being superseded by a more diffuse, multilayered system of authority.

Scholars in the field of migration studies recognize this text as a rigorous examination of the complexities inherent in contemporary border governance. Experts frequently cite the author's ability to synthesize disparate institutional layers into a coherent analytical model for students and researchers alike.
