After the conference committee agrees on a final draft of the bill, it is sent to the House of Representatives and the Senate for a final vote. The bill must pass both the Senate and the House with a majority vote. From there, it is on to the President for his signature . . .

After a bill is presented to the President, he has ten days (not counting Sundays) in which to sign it. If the President objects to the bill, he may return it with his objections to the house of Congress in which the bill originated. At that point, Congress may choose to vote on the bill again. If two-thirds of the House of Representatives and two-thirds of the Senate vote in favor of the bill, it will become law without the President's signature. If the President does not return the bill with his objections within ten days, it will still become a law as if he had signed it. If Congress adjourns within the ten days given to the President to sign the bill, this is called a "pocket veto" and the bill does not become a law. Once a bill is signed by the President, the bill becomes a law on that date, although it may not actually take effect until a later date.
