UNHCR was established on 14 December 1950[4] and succeeded the earlier United Nations Relief and Rehabilitation Administration. 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.
UNHCR’s mandate has gradually been expanded to include protecting and providing humanitarian assistance to whom it describes as other persons “of concern,” including internally displaced persons (IDPs) who would fit the legal definition of a refugee under the 1951 United Nations Convention Relating to the Status of Refugees and 1967 Protocol, the 1969 Organization for African Unity Convention, or some other treaty if they left their country, but who presently remain in their country of origin. UNHCR presently has major missions in Lebanon, South Sudan, Chad/Darfur, Democratic Republic of Congo, Iraq, Afghanistan as well as Kenya to assist and provide services to IDPs and refugees.

CHAPTER V
REFUGEES AND STATELESS PERSONS
5 . Protocol relating to the Status of Refugees
New York, 31 January 1967
United States of America
With the following reservations in respect of the application, in accordance with article I of the Protocol, of the Convention relating to the Status of Refugees, done at New York on 28 July 1951:
“The United States of America construes Article 29 of the Convention as applying only to refugees who are resident in the United States and reserves the right to tax refugees who are not residents of the United States in accordance with its general rules relating to non-resident aliens.
The United States of America accepts the obligation of paragraph 1 (b) of Article 24 of the Convention except insofar as that paragraph may conflict in certain instances with any provisions of title II (old age, survivors’ and disability insurance) or title XVIII (hospital and medical insurance for the aged) of the Social Security Act. As to any such provision, the United States will accord to refugees lawfully staying in its territory treatment no less favorable than is accorded aliens generally in the same circumstances.”
