The field of migration law is a broad legal area that is regulated by a number of legal documents that often do not specify foreigners as a group that falls under the given provisions. The area of refugee law is one of the few to which this statement could not applied because the 1951 Convention on the Rights of Refugees and the 1967 Protocol provided a solid legal framework for a range of international and national legal acts governing this area. There is also the indispensable role of the UNHCR as the UN agency in charge of custody of refugees and displaced persons. Unlike refugees, the issue of migrants' rights is the responsibility of various UNGS commissions, and it is more about rights of a socio-economic nature in general, with many rights also relating to migrants. This puts IOM, as the leading international organization for migration issues, in an unenviable situation. However, the practice so far has crystallized the legal framework that should be adhered to by all actors, from international organizations to states and their competent bodies to the non-governmental sector and civil society. The focus of this paper is this international legal framework and its application.
