2008 test · Question 38 of 100
What is the highest court in the United States?
Official USCIS answers
- the Supreme Court
Why this is the answer
The Supreme Court is the top court in the federal court system. It has the final say on cases about the U.S. Constitution and federal law, and its decisions cannot be appealed to a higher court.
💡 Memory tip: Think 'supreme' means highest — the Supreme Court sits at the very top.
