Tuna products are the main exports, and the main trading partner is the rest of the United States.

American Samoa consists of five main islands and two coral atolls. The largest and most populous island is Tutuila, with the Manua Islands, Rose Atoll and Swains Island also included in the territory. All islands except for Swains Island are part of the Samoan Islands, west of the Cook Islands, north of Tonga, and some 300 miles (500 km) south of Tokelau. To the west are the islands of the Wallis and Futuna group. As of 2021, the population of American Samoa is approximately 46,366 people.

Most American Samoans are bilingual and can speak English and Samoan fluently.American Samoa has been a member of the Pacific Community since 1983. American Samoa is noted for having the highest rate of military enlistment of any U.S. state or territory. As of September 9, 2014, the local U.S. Army recruiting station in Pago Pago was ranked first in production out of the 885 Army recruiting stations and centers under the United States Army Recruiting Command.American Samoa is the only major territory of the United States in which citizenship is not granted at birth, and people born there are considered "non-citizen nationals".

The United States Senate is the upper chamber of the United States Congress, with the House of Representatives being the lower chamber. Together they compose the national bicameral legislature of the United States.

The composition and powers of the Senate are established by Article One of the United States Constitution. The Senate is composed of senators, each of whom represents a single state in its entirety. Each state is equally represented by two senators who serve staggered terms of six years. There are currently 100 senators representing the 50 states. The vice president of the United States serves as presiding officer and president of the Senate by virtue of that office, and has a vote only if the senators are equally divided. In the vice president's absence, the president pro tempore, who is traditionally the senior member of the party holding a majority of seats, presides over the Senate.

As the upper chamber of Congress, the Senate has several powers of advice and consent which are unique to it. These include the approval of treaties, and the confirmation of Cabinet secretaries, federal judges (including Federal Supreme Court justices), flag officers, regulatory officials, ambassadors, other federal executive officials and federal uniformed officers. If no candidate receives a majority of electors for vice president, the duty falls to the Senate to elect one of the top two recipients of electors for that office. The Senate conducts trials of those impeached by the House.

The Senate is widely considered both a more deliberative and more prestigious body than the House of Representatives due to its longer terms, smaller size, and statewide constituencies, which historically led to a more collegial and less partisan atmosphere.From 1789 to 1913, senators were appointed by legislatures of the states they represented. They are now elected by popular vote following the ratification of the Seventeenth Amendment in 1913. In the early 1920s, the practice of majority and minority parties electing their floor leaders began. The Senate's legislative and executive business is managed and scheduled by the Senate majority leader.

The Senate chamber is located in the north wing of the Capitol Building in Washington, D.C.
