The Office of the United Nations High Commissioner for Refugees was established on December 14, 1950 by the United Nations General Assembly. The agency is mandated to lead and co-ordinate international action to protect refugees and resolve refugee problems worldwide. Its primary purpose is to safeguard the rights and well-being of refugees. It strives to ensure that everyone can exercise the right to seek asylum and find safe refuge in another State, with the option to return home voluntarily, integrate locally, or to resettle in a third country. It also has the mandate to help stateless people. Most UNHCR operations are in the field. The worldwide operation has become highly complex, ranging from recruitment of new staff and ensuring their security in dangerous situations to the procurement of everything from medical supplies and bulk food shipments to aircraft charters. Specific departments, mostly based in the Geneva headquarters, oversee key areas, such as operations, protection, external relations, human resources and finances. A number of regional bureaux liaise between overseas.
