In the contemporary globalised world, migration and flow of people across the world is an inevitable phenomenon. During the past few decades, the Persian Gulf region has been one such area, which has undergone tremendous economic development due to its oil economy. This oil boom in the Gulf Countries has attracted a large number of workers from around the world. South Asians constitute an important segment of this labour force. India along with Pakistan in the 1970s was the largest supplier of labour to Gulf Cooperation Council (GCC) countries. Subsequently, in the 1980s, the rest of the countries in South Asia – Sri Lanka, Nepal and Bangladesh also started sending skilled and semi-skilled labour to GCC states. At present, South Asians constitute the largest expatriate population in the GCC countries and their contribution in the socio-economic, technological and educational development of GCC countries is immense. The influx of workers from South Asia to the GCC countries has not received adequate attention this phenomenon deserves. This article not only highlights the problems and prospects of Asianisation of labour migration to the Persian Gulf countries, but also focuses on the multifaceted nuances of the South Asia–Gulf Corridor, clearly demonstrating as to how migration impacts both the receiving and sending countries.
