<em>The agreement between the head of the states that has not been ratified by the congress as treaties are called executive agreement. </em>Executive agreements are politically binding while the treaties are legally binding. The executive agreements are made by the President only. It is one of the mechanisms by which the US enters into binding international obligations. <em>Under US constitutional law the executive agreements are not considered to be treaties because as per the treaty clause a treaty requires the consent of two-third of the senate for qualifying it as a treaty.</em>
