This report is an attempt to provide a provisional comparative analysis of policies implemented in China, India, Argentina, and Mexico to facilitate the return of highly skilled expatriates and their professional reintegration. These countries differ in terms of the outbound and return flows of highly skilled professionals, as well as in the timing and intensity of the programs they have implemented. In general, career or business opportunities, and hence the offer of a conducive professional and socio-economic environment are central to attracting returnees. Migrant networks, temporary and permanent return migration programs exist in various forms and, apart from having their own merits, can complement each other in facilitating the return migration process. A long term, pluralistic and systemic approach, which in parallel to offering incentives involves the removal of administrative barriers, is considered to be important in bringing back and successfully reintegrating large numbers of highly skilled expatriates.
