This book provides an in-depth exploration of the evolving trends in South-South international migration to the Gulf Cooperation Council (GCC) countries. It presents a comprehensive analysis of migration dynamics from the perspectives of nationals, non-nationals, policymakers, and prospective migrants. It highlights the multifaceted factors driving migration to the Gulf, including the transition from oil-dependent economies to knowledge-based industries and the shift from a reliance on low-wage migrant workers to the integration of highly skilled expatriates. It emphasizes the Gulf states as strategic destinations for the Arab and Asian middle classes, shaped by global dynamics such as the gig economy, cultural compatibility, and socio-economic instability in migrants’ countries of origin.
