Changes

In the United States, all bills originating in the House of Representatives begin with "H.R." and all bills originating from the Senate begin with an "S."Joint resolutions also have the same effect as bills, and are titled as "H. J. Res." or "S. J. Res." depending on whether they originated in the House or Senate, respectively. This means that two different bills can have the same number. In the United States Congress, a joint resolution is a legislative measure that requires approval by the Senate and the House and is presented to the President for his approval or disapproval. However, joint resolutions used to propose amendments to the United States Constitution do not require the approval of the President. 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 then must — with one exception — be presented to the President and signed by him/her (or, re-passed in override of a presidential veto; or, remain unsigned for ten days while Congress is in session) to become a law. Laws enacted by virtue of a joint resolution are not distinguished from laws enacted by a bill, except that they are designated as resolutions as opposed to acts.
