What is the final step before a national bill can become a law?

The last step before the bill becomes law the signing of the bill by the president.

When the bill reaches the president, he has three choices namely:

1. he can sign and pass the bill

2. He can refuse to sign, or veto the bill, in which case the bill is returned to the house of representatives along with the  president's reasons  for thr veto.

3. Do nothing (pocket veto). In this case, if congress is in session, the bill automatically  becomes law, but if it is not in progress, the bill does not become law.
