Labour migration affects family economics in at least two ways: one is the outflow of indispensable family resources to meet the expenses incurred in the migration process and the other is the transfer in cash or kind from migrants to their non‐migrating families. This study primarily addresses the former flow, that is sources of funds for migration and resulting migrant indebtedness. Drawing on the experiences of Bangladeshi migrants in the GCC countries, this study explores the economic cost of migration, the extent of migrant indebtedness, and the implications of remittances on migrant families. This research exposes the complexity and multiplicity of the economic costs of migration to the GCC countries and reports that Bangladeshi migration to the Gulf states runs on debt, with migrants and their families indebting themselves in the migration process.
