The approach of states to managing immigration and asylum relies to a significant extent on the assignment of categories to people entering from abroad and residing in the country. Among these categories are regular migrant, labour migrant, irregular migrant, asylum seeker, refugee, unaccompanied child, smuggled migrant and trafficked person. Each of these categories has a specific definition in national law, and so every person migrating into a country fits into one of these categories – or at least that is how we understand migration and migration policies.
