An idea for a bill may come from anybody, however only Members of Congress can introduce a bill in Congress. Bills can be introduced at any time the House is in session. There are four basic types of legislation: bills; joint resolutions; concurrent resolutions; and simple resolutions. A bill's type must be determined.
The Bill Is Referred To The Senate
The bill is referred to the appropriate committee by the Speaker of the House or the presiding officer in the Senate. Most often, the actual referral decision is made by the House or Senate parliamentarian. Bills may be referred to more than one committee and it may be split so that parts are sent to different committees. The Speaker of the House may set time limits on committees.
The Bill Is Sent To The President
House: Debate is limited by the rules formulated in the Rules Committee. The Committee of the Whole debates and amends the bill but cannot technically pass it. Debate is guided by the Sponsoring Committee and time is divided equally between proponents and opponents. The Committee decides how much time to allot to each person. Amendments must be germane to the subject of a bill - no riders are allowed. The bill is reported back to the House (to itself) and is voted on.
The Bill Becomes A Law
f the bill passes by simple majority (218 of 435), the bill moves to the Senate. In the Senate, the bill is assigned to another committee and, if released, debated and voted on. Again, a simple majority (51 of 100) passes the bill.
A bill becomes law if signed by the President or if not signed within 10 days and Congress is in session. If Congress adjourns before the 10 days and the President has not signed the bill then it does not become law
Once a bill is signed by the President or his veto is overridden by both houses it becomes a law and is assigned an official number.
