Based on fieldwork material from Lao People's Democratic Republic, this paper introduces an analytical framework that transcends compartmentalized approaches towards migration involving young people. The notions of fluid and institutionalized forms of migration illuminate key differences and commonalities in the relational fabric underpinning empirically diverse migration scenarios. Applying this framework to the role of networks in becoming a young migrant, this chapter sheds light on young migrants' differential scope for exercising agency. This redirects concerns about young migrants away from descriptive and static factors towards their relational position in the process of migration, which shapes their agency and vulnerability.
