The U.S. Embassy in South Korea has not paid rent for using its site since 1980. The amount of rent over the past 38 years exceeds 90 billion won ($79 million). The reason for this has been stated that operations of the United States Agency for International Development-Korea (USAID-Korea), and its predecessor United States Operations Mission (USOM) have long since come to an end, and this removes legal grounds for free use of the embassy building.
