Studies about international migrant students in primary school are increasingly frequent in the educational literature. There is a strengthening on the production of international scholarship that seek to guide the debate on international migration policies and the defense of the right to education as a fundamental human right regardless of status, citizenship, or the existence of official identity documents, a right guaranteed by the Universal Declaration of the Rights of the Child. International migration processes are multiple and heterogeneous. The origins of migration are plural, as are the forms of reception in the countries of destination or transit. In the field of educational policy, researches observe that international migrant students may go through totally different schooling processes, with very different reception and permanence policies, depending on the school, education network or country in which they are. In this heterogeneous and complex international context, we present this dossier with the aim of contributing to an expanded reflection on the educational policies compared to international migrant populations in different countries, guaranteeing a multiplicity of voices, theoretical perspectives and fields of study.
