In order to become a law a bill in congress must?

In order to become a law, a bill in Congress must first be introduced in either the House of Representatives or the Senate. It must then go through a series of steps, including committee review, debate, and voting in both chambers. If both the House and Senate pass the bill, it is sent to the President for approval. If the President signs the bill, it becomes law; if not, Congress can override the veto with a two-thirds majority in both chambers.
