Migration is the physical process of moving from one geographical area to another, either within the same country or across national borders. Reasons for migration can be economic, political, or educational, and each brings with it certain challenges. In addition, people may migrate alone, with their families, or as a group. Each of these steps may have pre-migration stressors or trauma, the physical process of migration, and post-migration acculturation and settling down. Post-migration individuals may have to deal with trauma, cultural bereavement, cultural shock, and cultural conflict. Various push and pull factors have been described, which include push factors due to climate change, wars, conflicts, disasters, etc., and pull factors such as economic betterment. Migration can be short-term, temporary, medium-term, long-term, or permanent. Even if two people move at the same time for similar reasons, their migratory experiences will vary. The expectations of the new place and the sense of loss at leaving the old place can be extremely brutal. Whether there is time to plan and arrange migration or whether it is sudden, the individual may still be unprepared. In this chapter, we describe the impact and understanding of the trauma that migrants may have to deal with. Using case examples, we illustrate some of the challenges and offer solutions.
