South Asia is a remittance economy. South Asian countries send out a significant number of migrant workers annually and remittances sent by migrant workers become a significant source of funds for economic development of the countries. Most governments in South Asia view worker migration as helping to curtail unemployment, reduce poverty, and earn foreign exchange through remittances, and make worker migration as one of the key economic policy priorities.
