Anyone may draft a bill; however, only members of Congress can introduce legislation, and by doing so become the sponsor(s). There are four basic types of legislation: bills; joint resolutions; concurrent resolutions; and simple resolutions. The official legislative process begins when a bill or resolution is numbered, (H.R. signifies a House bill and S. a Senate bill), referred to a committee, and printed by the Government Printing Office.

The following are the steps of legislative procedure:

  1. An idea must first come from the public. Ideas originate and are transmitted to Congress by lobbyists, public interest groups, PAC's, and grassroots political movements. 
  2. A member of Congress, either a Senator or Representative must then sponsor the bill. 
  3. The bill must be introduced to the floor of the House or Senate. 
  4. Referral Committee: With few exceptions, bills are referred to standing committees in the House or Senate according to carefully delineated rules of procedure. 
  5. Committee Action: When a bill reaches a committee it is placed on the committee's calendar. A bill can be referred to a subcommittee or considered by the committee as a whole. It is at this point that a bill is examined carefully and its chances for passage are determined. If the committee does not act on a bill, it is the equivalent of killing it. The Committee Chair has the right to "pigeonhole" (not assign or hear debate on the bill) thus killing it. 
  6. Subcommittee Review: Often, bills are referred to a subcommittee for study and hearings. Hearings provide the opportunity to put on the record the views of the executive branch, experts, other public officials, supporters, and opponents of the legislation. If a subcommittee votes not to report legislation to the full committee, the bill dies.
  7. Committee Action to Report a Bill: After receiving a subcommittee's report on a bill, the full committee can conduct further study and hearings, or it can vote on the subcommittee's recommendations and any proposed amendments. The full committee then votes on its recommendation to the House or Senate.
  8. Schedule Floor Action: After a bill is reported back to the chamber where it originated, it is placed in chronological order on the calendar.
  9. Debate: When a bill reaches the floor of the House or Senate, there are rules and procedures governing the debate on legislation. Amendments may be added to the bill at this time.
  10. Voting: After the debate and the approval of any amendments, the bill is passed or defeated by the members voting.
  11. Referral to Other Chamber: When a bill is passed by the House or Senate it is referred to the other chamber where it usually follows the same route through committee and floor action. This chamber may approve the bill as received, reject it, ignore it, or change it. 
  12. Conference Committee Action: If only minor changes are made to a bill by the other chamber, it is common for the legislation to go directly to the President for signature. However, when the actions of the other chamber significantly alter the bill, a conference committee is formed to reconcile the differences between the House and Senate versions. If the conferees are unable to reach agreement, the legislation dies. If agreement is reached, a conference report is prepared describing the committee members' recommendations for changes. Both the House and Senate must approve the conference report. 
  13. Final Action: After a bill has been approved by both the House and Senate in identical form, it is sent to the President. If the President approves of the legislation, he signs it and it becomes law. Or, the President can take no action for ten days, while congress is in session, and it automatically becomes law. If the President opposes the bill he can veto it; or if he takes no action after the Congress has adjourned its second session, it is a "pocket veto" and the legislation dies. 
  14. Overriding a Veto: If the President vetoes a bill, Congress may attempt to "override the veto." This requires a two thirds roll call vote of each chamber of Congress.
