A United Nations laissez-passer is a diplomatic travel document issued by the United Nations under the provisions of Article VII of the 1946 Convention on the Privileges and Immunities of the United Nations in its offices in New York and Geneva, as well as by the International Labour Organization.
The UNLP is issued to UN and ILO staff as well as staff members of international organizations such as the WHO, the IAEA, the World Tourism Organization, the Comprehensive Nuclear-Test-Ban Treaty Organization Preparatory Commission, the Organisation for the Prohibition of Chemical Weapons, the World Trade Organization, the International Monetary Fund, the International Organization for Migration, the World Intellectual Property Organization and the World Bank. The document is written in English and French, the working languages of the United Nations.
The UNLP is a valid travel document, which can be used like a national
passport. However, UNLP holders often encounter immigration officials who are
unfamiliar with the document and require them to show a national passport in
addition.
