If the president negotiate a treaty with another nation, when does it become law in the United States is it after it is approved by both houses of Congress after it is approved by the house of representatives after it is approved by the Senate or after it is approved by the Supreme Court

According to the process defined in the United States Constitution, a treaty negotiated by the President becomes law after it is approved by the Senate. The approval of both houses of Congress, i.e., the House of Representatives and the Senate, is not required for a treaty to become law. The Supreme Court also does not play a role in approving treaties; rather, it interprets and applies them if a dispute arises.
