In the United States Congress, a joint resolution is a legislative measure that requires passage by the Senate and the House of Representatives and is presented to the President for his approval or disapproval. Generally, there is no legal difference between a joint resolution and a bill. Both must be passed, in exactly the same form, by both chambers of Congress, and signed by the President (or, re-passed in override of a presidential veto; or, remain unsigned for ten days while Congress is in session) to become a law.
