18. How many U.S. Senators are there?
American Government · System of Government
Accepted answer(s)
- one hundred (100)
USCIS officers ask this on the 2008 Civics Test because understanding "american government" is core to how the U.S. system works day to day. Memorize the exact answer above rather than a paraphrase — officers accept the wording USCIS publishes, and "one hundred (100)" is the safest phrasing to say out loud in the interview.
This is question 18 of the 2008 Civics Test. See it on uscis.gov. This question is worded the same way on the 2025 Civics Test.
