This regional study commissioned by The Asia Foundation entitled “Labour Migration: Trends and Patterns” examines the patterns and process of labour migration by Nepali and Bangladeshi migrant workers using formal and informal channels for migration primarily to Gulf countries. The study provides insights into the dimensions of both regular and irregular labour migration and reviews the links, if any, with labour exploitation and human trafficking; and examines factors promoting undocumented migration that leads to increased vulnerability. The study examines the challenges posed to safe labour migration along the regional migration corridor of Bangladesh, India, and Nepal. It also highlights some salient features that threaten safe mobility of people between and through these three countries.
