Territories of the United States
Territories have always been a part of the United States. According to federal law, the term "United States", when used in a geographical sense, means "the continental United States, Alaska, Hawaii, Puerto Rico, Guam, and the United States Virgin Islands". Since political union with the Northern Mariana Islands in 1986, they too are treated as a part of the U.S. An executive order adopted in 2007 includes American Samoa in the U.S. "geographical extent" as reflected in U.S. Department of State documents.
