Who signs bills to become laws?

Why This Matters

The President signs bills to become laws. This is one of the most important powers of the executive branch. After Congress passes a bill, meaning both the House of Representatives and the Senate vote to approve it, the bill goes to the President's desk. The President then decides whether to sign it into law or reject it.

When the President signs a bill, it officially becomes a law of the United States. This is the last step in the lawmaking process. The entire journey of a law, from an idea, to a bill introduced in Congress, to debates and votes in both chambers, ends with the President's signature. Without that signature, the bill does not become law (unless Congress overrides a veto, which is a separate process).

This power gives the President a major role in shaping the laws of the country, even though the President does not write the bills. The President can use the threat of refusing to sign a bill as a way to influence what Congress includes in the legislation. For the USCIS test, remember that the President is the one who signs bills into law. This is a basic part of how the three branches of government work together.

Study Tip

Follow the journey of a law in your mind: Congress writes and votes, then the President signs. Think of the President as the final stamp of approval. Without that stamp, the bill just sits on the desk. "Who signs?", the President. Keep it simple.
