Labor migration is a rising global issue. In Asia and the Pacific region, it is a structural reality, as the region is not only comprised of major migrant countries of origin, but also traditional and emerging destination countries. As the greater flow of people across national boundaries improved labor markets, it also created new challenges including limited legal rights, discrimination, social exclusion and the lack of social security especially to migrant workers. To strengthen migrant worker protection, entering into social security agreement is a viable option to ensure portability of social security entitlements.
