The problem of international migration is that global cooperation is somewhat rare. If international cooperation is to develop, then it will depend on states; but effective cooperation would also impose real constraints on states. Moreover, as states and their borders give meaning to international migration, it follows that the development, consolidation, and transformation of the state system is a key factor determining the possibilities for the global and regional governance of migration to develop. Existing forms of regional integration and their migration provisions as well as regional consultation processes (RCPs) can serve as a mechanism for intraregional communication, the sharing of knowledge, and for the dissemination of policy ideas and practices. The EU has already been discussed as the world’s most highly developed form of regional integration. It is the only international organization with the power and capacity to make and implement laws through its own institutional system that must be implemented by member states. The EU moreover has a highly developed system of internal free movement for nationals of its own states and has developed a border-free travel area for participating states. These developments constitute the hallmark of a highly developed intra-EU migration framework linked to the creation of the “single market.”

Evidence shows that international flows of highly skilled workers are increasing, both between advanced states and between advanced and developing regions. The movement of skilled people around the globe is driven by a variety of political forces, including governments’ continued efforts to address domestic labor shortages and restock through preferential immigration policies and international recruitment drives. For social scientists, the unprecedented movement of highly skilled labor across the globe calls into question earlier approaches to the study of migration. Where international highly skilled workers were treated in the classical sociological literature on migration as a small population that reflected both the potential for human capital transfers between states and, more controversially, a corresponding “brain drain” from source countries, the realities of transnational migration now complicate this picture. The expansion of the European Union and other forms of regional cooperation have given rise to important trade liberalizing agreements, producing a truly global migration market and the policy context for much contemporary research. More studies are needed to tackle issues relevant to the study of skilled migration, such as estimates of skilled migrants, longitudinal studies of circular migration, and analyses of the differentiation of migrants by occupational group and country of origin, along with the relative access that such groups enjoy in the receiving state.
