Except that
Most of the employees of the UN HQ in NY are Americans.
About 16,000 people (with combined salaries of $850 million annually) are employed locally by the UN Secretariat, specialized agencies, consulates and foreign missions. The United Nations and its related organizations put more people to work in this city - people who spend some of their salaries here - than do private employers such as Con Edison and Citicorp. At the Secretariat itself, most of these employees are Americans.
