Migration is an essential issue in South Asia because of its complex patterns of internal, regional, and global mobility that are influenced by social, political, economic, and environmental factors. Despite their shared history, culture, and economy, South Asian countries face a number of challenges when it comes to managing migration. Regional organizations like SAARC, BIMSTEC, SASEC, and others have been critical in addressing migratory issues, despite the fact that their effectiveness has been shaped by national interests, regional power dynamics, and the unequal relationships among the South Asian states. The chapter argues that, despite the fact that migration is a critical issue in South Asia, regional political barriers such as member-state bilateral disputes, institutional and financial constraints, and SAARC’s inaction have reduced the effectiveness of regional cooperation and complicated cross-border policy implementation.
