They are considered treaties as the term is used under international law in that they bind both the United States and a foreign state.

An executive agreement can only be negotiated and entered into through the president's authority (1) in foreign policy, (2) as commander-in-chief of the armed forces, or (3) from a prior act of Congress. For instance, it is as commander-in-chief that the President negotiates and enters into status of forces agreements (SOFAs), which govern the treatment and disposition of U.S. forces stationed in other nations. An executive agreement, however, cannot go beyond the President's constitutional powers. If an agreement was in the competence of the United States Congress, it would need to become a congressional-executive agreement or a treaty with Senate advice and consent. If an agreement was neither within the competence of Congress nor within the competence of the President (as for example an agreement which would affect powers reserved to the states), it could still be adopted by the President/Senate method but must not conflict with the United States Constitution. One should note that in contrast with many other nations (particularly in Europe), the United States does not consider international agreements to take precedence over domestic law. A Status of Forces Agreement (SOFA) is an agreement between a country and a foreign nation stationing military forces in that country. ... Congress in Joint Session. ...
