The large population in a country is not comparable to the number of job opportunities in that country, so many citizens look for work abroad as migrant workers. International legal protection is needed for migrant workers through international organizations/institutions such as the International Labor Organization (ILO). The research method used is a normative legal research method. This research discusses how Indonesian migrant workers are regulated in international law, where protection for migrant workers is contained in the International Convention Concerning the Protection of the Rights of All Migrant Workers and Their Family Members. The Convention was declared in New York on December 18 1990 against crimes against migrant workers such as human trafficking, unpaid wages, recruitment of undocumented or illegal workers, and even the death of migrant workers in the destination country.
