HaMi (Happy Migration App) is a mobile platform developed by the K-HaMi Project to support Nepali migrant workers during the pre-migration, migration, and post-migration phases. The app offers practical guidance, skill development, financial planning, and mental health support, targeting Nepali migrant workers heading to various destinations. Key features include pre-departure preparation, self-development tools, reintegration support (employment, business, investment, and government programs), community stories, and a Q&A help system. With a user-friendly interface in both Nepali and English, HaMi serves as a lifelong companion for migrant workers—empowering them with knowledge, confidence, and continuous support throughout their journey.
