What is the supreme law of the land?

Why This Matters

This is often one of the first questions asked during the USCIS civics portion of your naturalization interview. The interviewer wants to know that you understand the most fundamental concept in American government: the Constitution is the highest authority in the land.

The Constitution was written in 1787 and has been the foundation of the United States government ever since. Every law passed by Congress, every executive order signed by the President, and every court ruling must be consistent with the Constitution. If a law conflicts with the Constitution, the Supreme Court can strike it down, this is called judicial review.

For citizenship applicants, this question tests whether you understand that the United States is a nation governed by a written document, not by the personal authority of any individual leader. This principle, that the law is supreme, not any person, is central to American democracy.

Key Facts

• The Constitution was written at the Constitutional Convention in Philadelphia in 1787
• It replaced the earlier Articles of Confederation, which gave too little power to the national government
• The Constitution has been amended 27 times, with the first 10 amendments known as the Bill of Rights
• The Constitution establishes the three branches of government: legislative, executive, and judicial

Common Mistakes

• Saying "the Bill of Rights" instead of "the Constitution", the Bill of Rights is part of the Constitution, but the Constitution itself is the supreme law
• Saying "the Declaration of Independence", this document declared freedom from Britain but does not establish any laws or government structure
• Confusing the Constitution with specific laws or amendments, the Constitution is the framework, not any single law within it

Study Tip

Think of the Constitution as the "rulebook" for the entire country. Every other law, rule, or government action must follow this rulebook. If you remember that the Constitution is the one document everything else must obey, this answer becomes easy to recall.
