Official USCIS answers
- nine (9)
This answer changes with elections or appointments. Check uscis.gov/citizenship/testupdates before your interview.
Why this is the answer
The Supreme Court is made up of nine justices: one Chief Justice and eight Associate Justices. This number has stayed at nine since 1869, and it is set by Congress, not the Constitution.
💡 Memory tip: Think 'nine judges, one bench' — the Supreme Court always has nine justices.
This is the 2008 test, for N-400s filed before October 20, 2025. Filed on or after that date? Use the 2025 test.
