This book aims to portray migratory experiences, documented in the form of biographical narratives. We are interested in the dynamic aspect of migration, which effectively becomes a complex trajectory, made up of stages, returns, and circulations and no longer simply, as in the industrial era, a bipolar exile (there and here). In these complex and dynamic movements, many trajectories become bifurcations, by which we mean shifting fates. In these stories we found paths, events, and bifurcations, all combined together, in terms of biographical construction based on accumulated experiences. These narratives are both very banal and very unusual journeys, portraying a new international human globalization. They are simultaneously stories of barriers to be crossed in chaotic situations interspersed with peaceful events in quiet contexts. These journeys reveal not only the weight of migration policies, but also the certification policies implemented and developed by various countries. This book presents itineraries, social logics of mobility; the routes become the analysts. If statistics record regularities, the personal approach captures specificities that produce meaning and contribute to a reinterpretation of current forms of mobility.
