What is the supreme law of the land?
Official USCIS answers

Why this is the answer
The Constitution is the highest law in the United States. All other laws and the government itself must follow it. That is why it is called the supreme law of the land.
💡 Memory tip: Think 'supreme' means top: the Constitution sits at the very top of all laws.
