However, the Supreme Court has not yet made a final decision on this matter. In the United States, executive agreements are binding internationally when negotiated and concluded under the authority of the president on foreign policy, commander-in-chief of the armed forces, or a previous act of Congress. For example, the president, as commander-in-chief, negotiates and enters into status of forces agreements (SOFAs) governing the treatment and disposition of U.S. armed forces stationed in other nations. The President may not, however, unilaterally conclude executive agreements on matters not within his constitutional authority. . . .
