The USCIS civics test draws from a fixed bank of 128 questions. While most of those questions are straightforward once you've studied them, a handful consistently trip up applicants — not because they're obscure, but because the correct answer is counterintuitive or the wording is easy to confuse with a similar question. Here are 10 questions worth paying special attention to.
1. What is the supreme law of the land?
Many applicants say 'the Bill of Rights' or 'federal law.' The correct answer is the Constitution. The Bill of Rights is the first ten amendments to the Constitution — important, but not the supreme law itself. Federal law and Supreme Court decisions must also be consistent with the Constitution.
2. What do we call the first ten amendments to the Constitution?
This is the reverse of Question 1. Here the answer is the Bill of Rights — not the Constitution. These two questions test your ability to distinguish between the document and its amendments. If you confuse them in either direction, you'll miss both.
3. How many amendments does the Constitution have?
The answer is twenty-seven (27). Many applicants say 10 — the number of amendments in the Bill of Rights. The Constitution has been amended 27 times in total. The 27th Amendment, ratified in 1992, addresses congressional pay.
4. What is the economic system in the United States?
The accepted answers are capitalist economy or market economy. Some applicants answer 'free enterprise,' which is also accepted. What USCIS is not looking for: democracy, republic, or any description of the political system. This question is specifically about economics.
5. There are four amendments to the Constitution about who can vote. Describe one of them.
This question requires knowing something specific. The four voting-rights amendments are: citizens 18 and older can vote (26th Amendment); any citizen can vote — women's suffrage (19th Amendment); citizens of any race can vote (15th Amendment); and you don't have to pay to vote — no poll tax in federal elections (24th Amendment). Applicants often miss this because they focus on landmark amendments and overlook the poll tax angle.
6. What is the name of the Speaker of the House of Representatives now?
This is a 'current official' question — the answer changes when leadership changes. As of 2025, the Speaker of the House is Mike Johnson. Always verify the current answer on uscis.gov before your interview, since USCIS updates these answers when officials change.
7. What territory did the United States buy from France in 1803?
The answer is the Louisiana Territory (also accepted: Louisiana). A common wrong answer is 'Louisiana' referring to the state — but the purchase was an enormous territory covering roughly 15 current U.S. states, not just the state of Louisiana. Either phrasing is accepted.
8. Name one war fought by the United States in the 1900s.
There are several acceptable answers: World War I, World War II, the Korean War, the Vietnam War, and the Persian Gulf War. The most common mistake here isn't giving a wrong answer — it's giving a vague or incorrectly named answer. 'The Gulf War' is fine; 'the Iraq War' technically refers to the 2003 conflict and may not be accepted depending on how it's interpreted.
9. What movement tried to end racial discrimination?
The correct answer is the civil rights (movement). Applicants sometimes say 'the abolition movement' (which ended slavery, not segregation), or give a broader answer about equality that the officer may not count. Be specific: civil rights movement.
10. What is one thing Benjamin Franklin is famous for?
There are multiple accepted answers: U.S. diplomat, oldest member of the Constitutional Convention, first Postmaster General, writer of 'Poor Richard's Almanac,' and started the first free libraries. Many applicants say he 'invented electricity' or 'discovered electricity' — neither is an accepted answer. The correct science-related answer, if you want to go that route, is that he was a U.S. scientist.
These questions share a common thread: the wrong answer is plausible. They're not trick questions, but they reward precision. Knowing why the correct answer is correct — not just what it is — is the best way to avoid these common mistakes at your naturalization interview.
Frequently asked questions
Which civics test questions are most likely to appear?
USCIS draws questions randomly from the full 128-question bank, so every question has a chance of appearing. That said, questions about the Constitution, branches of government, and the Bill of Rights come up most frequently due to the size of those topic areas.
Can I give a partial answer on the civics test?
Some questions accept multiple answers and you only need to provide one. For questions that require a specific answer, a partial or vague response may not be accepted. When in doubt, give the most precise answer you know.
What happens if I answer a question wrong?
The officer continues asking questions until you reach 12 correct answers or 20 questions are exhausted. Answering one question wrong does not end the test — you still have remaining questions to reach the passing threshold.
