The International Organizations Immunities Act is a United States federal law since 1945. It "established a special group of foreign or international organizations whose members could work in the U.S. and enjoy certain exemptions from US taxes and search and seizure laws". These advantages are usually given to diplomatic bodies. The 79th United States Congress passed the International Organization Immunities Act on December 29, 1945; the Act can be found under Title 22, chapter 7, sub-chapter XVIII.
