Executive agreement, an agreement between the United States and a foreign government that is less formal than a treaty and is not subject to the constitutional requirement for ratification by two-thirds of the U.S. Senate. Although the two agreements are both treaties and agreements between Congress and the Executive, they are legally different instruments. For example, agreements between Congress and the executive branch cannot deal with matters outside the listed powers of Congress and the President (those powers, which were expressly granted to Congress and the President in Article I, Section 8 and Section II, Section 2, of the U.S. Constitution), while treaties can do so. Moreover, according to the Constitution, a treaty will only be ratified if at least two-thirds of the Senate votes in favour of it. On the other hand, an executive agreement of Congress with a single simple majority becomes mandatory in both houses of Congress. Agreements between Congress and the executive branch should not be confused with executive agreements reached by the president alone. In the United States, executive agreements are binding at the international level when negotiated and concluded under the authority of the President on foreign policy, as commander-in-chief of the armed forces or from a previous congressional record. For example, the President, as Commander-in-Chief, negotiates and concludes Armed Forces Agreements (SOFAs) that govern the treatment and disposition of U.S. forces deployed in other nations. However, the President cannot unilaterally enter into executive agreements on matters that are not in his constitutional jurisdiction.
In such cases, an agreement should take the form of an agreement between Congress and the executive branch or a contract with the Council and the approval of the Senate.  The U.S. Supreme Court, United States v. Pink (1942) found that international executive agreements, validly concluded, have the same legal status as treaties and do not require Senate approval. To Reid v. Concealed (1957), the Tribunal, while reaffirming the President`s ability to enter into executive agreements, found that such agreements could not be contrary to existing federal law or the Constitution. Most executive agreements were concluded in accordance with a treaty or an act of Congress. However, presidents have sometimes reached executive agreements to achieve goals that would not find the support of two-thirds of the Senate. For example, after the outbreak of World War II, but before the Americans entered the conflict, President Franklin D.
