In 1991, Hungary became a member state of IOM and the following year, the organization established its office in Budapest. Since the signature of the agreement between IOM and the Hungarian Government (7 April 1992), the IOM Mission enjoys diplomatic status. Throughout the 1990s IOM has managed numerous projects in the fields of counter-trafficking, migration and health, assisted voluntary return and assistance to migrants in transit and run several public information campaigns on migration issues in Hungary.

The IOM office in Hungary has been actively involved in building capacity of the Hungarian government to manage migration issues through training, organizing regional and international exchange programs, conferences and research projects. IOM Budapest has also established partnerships with a number of relevant non-governmental organizations assisting migrants and victims of trafficking in Hungary.

During November 200 and July 2011 the office of IOM Budapest functioned as a “Mission with Regional Functions” providing direct support, supervision and assistance to the IOM missions in the region of Central Europe.

Since July 2011, IOM Budapest is the Country Mission for Hungary. The IOM Budapest office has a Finance, Administration and Human Resources Department, a Project Development and Implementation Unit and an Operations Department.
