The law of the United States is a complex system built on the United States Constitution. It combines federal laws, state laws, and local regulations, making it one of the most structured legal systems in the world.


1. Federal Law

Federal laws apply across the entire country. These laws are created by Congress and interpreted by courts like the Supreme Court of the United States.

Examples include:

  • Immigration law
  • Federal criminal law

2. State Law

Each U.S. state has its own laws. For example, laws in California may differ from those in Texas.

State laws cover:

  • Property
  • Family law

Cities and counties create local laws (ordinances), such as:

  • Traffic rules
  • Zoning laws
