1. 直到 1950 年，关岛一直由美利坚合众国海军部管理。美国国会于该年颁布《关岛组织法》，成立了地方政府机构，使关岛成为未并入、拥有有限自治权的美国领土。此后，该领土一直由内政部管理。关岛是未并入的领土，原因是《美国宪法》条款在该岛并不完全适用。因此，关岛只是美国属地，但不是美国的一部分。
1. Guam was administered by the Department of the Navy of the United States of America until 1950, when the United States Congress enacted the Organic Act of Guam, which established institutions of local government and made Guam an unincorporated territory of the United States with limited self-governing authority. Since then, the Territory has been administered by the Department of the Interior. Guam is an unincorporated territory, since not all provisions of the Constitution of the United States apply to the island. As such, Guam is a possession but not part of the United States.
