Human migration is as ancient as humanity itself. While this fact is easy to identify, explaining its causes, processes, manifestations, and consequences is far more complex. Existing theories have largely focused on studying the causes of migration, but they differ significantly in analyzing its consequences. Some consider migration to be a temporary process, while others view it as a permanent and inherent feature of the capitalist World-System. The conclusion emphasizes the necessity of conducting comprehensive, interdisciplinary studies that encompass the phenomenon in all its complexity, while also recognizing that any theory is only applicable to a specific time and place.
