Migratory flows have developed in parallel with the evolution of societies throughout history, shaping an increasingly dynamic and multifaceted reality where diversity is at the core. Various reasons motivate the mobility of population, but today labour needs stand out as one of the most important ones. The initial neoclassical theories of migration studies from the early twentieth century conceptualised “economic migrants” as the positive outcome of the rational calculation of the cost-benefit of moving to another place, most often from those countries with an abundant workforce and low wages to those countries with scarce labour and higher wages. Such theories have been revised in the light of contemporary changes of the last decades, which do not frame anymore the act of migrating as a result of an individual and deliberate election, but rather as the result of global processes in an increasing interdependent world. Such changes include the growing political and legal restrictions to the mobility of people, the greater heterogeneous composition of migratory flows and the rising transnational character of spaces and communities, to name just a few (Arango, 2003).
