where is headquarters located
There are four United Nations Headquarters, so to speak. The first one, which is their international headquarters, is in New York, New York, The United States of America. There are three additional regional headquarters located at Geneva, Switzerland, Vienna, Austria, and Nairobi, Kenya. Technically, the land on which these headquarters lie is extraterritorial, which means that the land is part of the United Nations, not the United States, by treaty.
The corporate headquarters may or may not be in the location in which the business is incorporated or where the majority of its employees work. Offices of a business that are not the corporate headquarters are called branch offices.
