100 vs 128: which U.S. citizenship test do you take?

If you're preparing for the U.S. naturalization civics test, the first thing to get right is which version you'll take: the older 100-question test or the newer 128-question test. Study the wrong list and you could walk into your interview prepared for the wrong questions. The good news is that figuring out your version takes about ten seconds, because it's decided by one thing: the date you filed your Form N-400.

The short answer

• Filed Form N-400 before October 20, 2025? You take the 2008 civics test: 100 questions total, the officer asks up to 10, and you need 6 correct to pass.
• Filed on or after October 20, 2025? You take the 2025 civics test: 128 questions total, the officer asks 20, and you need 12 correct to pass.

The English portion of the test (reading, writing, and speaking) did not change. Only the civics questions did.

What changed on October 20, 2025

USCIS introduced an updated civics test that applies based on your application filing date. Applicants who filed before the cutoff continue with the long-standing 2008 test, while those filing on or after the cutoff take the expanded 2025 test. The 2025 version has more questions in the study pool (128 instead of 100), asks more of them at the interview (20 instead of 10), and requires more correct answers to pass (12 instead of 6).

USCIS did not retire the older test. Both versions run in parallel, and USCIS publishes official study materials for each one. The officer's behavior differs slightly between them too: on the 2025 test, the officer stops asking as soon as you answer 12 questions correctly or 9 incorrectly; on the 2008 test, the officer stops as soon as you reach 6 correct answers.

Because two versions are in use at the same time, a lot of older study material online still describes only the 100-question format. Always match your study list to your filing date.

How to tell which version you take

Use this quick check:

1. Find your N-400 filing date. This is the date USCIS received your naturalization application (check your receipt notice, Form I-797C).
2. Compare it to October 20, 2025. Before that date, you take the 100-question (2008) test. On or after, you take the 128-question (2025) test.
3. When in doubt, go by the receipt date on your USCIS notice, and confirm your test version with USCIS or your attorney or accredited representative.

The exact date matters more than the month or the year. An application USCIS received on October 19, 2025 falls under the 2008 test; one received on October 20, 2025 falls under the 2025 test. And once the filing date sets your version, it stays set: an interview scheduled in 2026 or later does not move you to the newer test.

100-question vs 128-question test: side by side

Both tests are oral. A USCIS officer asks the questions out loud during your interview, and you answer out loud.

Are the 128 questions the same as the 100?

No. The two versions use separate official lists, and one is not just a longer copy of the other. The subjects overlap, but the wording of the questions, the accepted answers, and the section structure all differ.

Both lists cover American government (principles, system of government, rights and responsibilities) and American history (colonial period and independence, the 1800s, recent history). The 2008 list then adds an Integrated Civics section with geography, symbols, and holidays. The 2025 list instead has its own Symbols and Holidays section and no separate geography block.

Each version also has its own designated 65/20 set, marked with an asterisk on that list. The practical rule stays simple: once you know your version, study only that list, because that is the one your officer will use.

Did the English test change?

No. Regardless of which civics version you take, the English requirement is the same: you read one of three sentences correctly, write one of three sentences correctly, and demonstrate the ability to speak and understand basic English during your interview. USCIS publishes reading and writing vocabulary lists you can study in advance, and the officer judges your speaking through the normal interview questions about your application. If you're brushing up on English, that part of your preparation applies either way.

Special consideration: the 65/20 test

If you are 65 or older and have been a lawful permanent resident for 20 or more years, USCIS gives you a shorter, specially selected civics test. You're asked 10 questions from a designated pool of 20, and you need 6 correct to pass. These special questions are marked with an asterisk (*) on the official question lists, so you can focus your studying on just those 20.

This special consideration applies under both versions: if you filed before October 20, 2025, your 20 questions come from the 2008 list; if you filed on or after, they come from the 2025 list. This is about the civics test. The English requirements and other eligibility rules are separate.

Which questions should you study?

Once you know your version, study only that list so your practice matches the interview:

• On the 2008 test? Study the 100-question list and practice with the 100-question tools.
• On the 2025 test? Study the 128-question list and practice with the 128-question tools.
• Eligible for 65/20? Focus on the 20 asterisked questions from your version's list.

Keep in mind that a few answers change over time, such as questions about current elected officials. Always answer with the official who is serving at the time of your interview, and re-check those answers close to your appointment.

Frequently asked questions

Which citizenship test do I take if I filed my N-400 in 2025?

It depends on the exact date. If you filed Form N-400 before October 20, 2025, you take the 100-question (2008) test. If you filed on or after October 20, 2025, you take the 128-question (2025) test. The month alone is not enough: an application filed on October 19, 2025 gets the 2008 test, and one filed on October 20, 2025 gets the 2025 test.

What if I filed before October 20, 2025 but my interview is in 2026?

You still take the 100-question (2008) test. The filing date controls which version you get, not the interview date. Many applicants who filed in 2025 are interviewed months later and worry the newer test will apply to them. It does not. Check the receipt date on your Form I-797C receipt notice and study the list that matches it.

Can I choose which civics test to take?

No. USCIS assigns the version based on your N-400 filing date, and the officer administers that version at your interview. There is no option to request the shorter or the newer list. The only variation is the 65/20 special consideration, which is based on your age and years as a permanent resident, not on a choice.

Is the 128-question test harder than the 100-question test?

The 2025 test asks more of you by the numbers: the study pool is larger (128 questions instead of 100), the officer asks more questions (20 instead of up to 10), and you need more correct answers (12 instead of 6). The format is the same, though: an oral test on American government, history, and civics, drawn from a published list you can study in advance.

Do the two tests use the same questions?

No. Each version has its own official list. The subjects overlap, but the wording, the answer sets, and the section structure differ. The 2008 list includes a geography section under Integrated Civics; the 2025 list instead has a Symbols and Holidays section. Study only the list for your version so your practice matches your interview.

Does the 65/20 special consideration apply to the 128-question test?

Yes. The 65/20 special consideration applies under both versions. If you are 65 or older and have been a lawful permanent resident for 20 or more years, you are asked 10 questions from a designated pool of 20 taken from your version's list, and you need 6 correct to pass. The designated questions are marked with an asterisk on the official lists.

Where can I find my N-400 filing date?

Look at your receipt notice, Form I-797C. USCIS mails it after receiving your application, and the receipt date on it is the date that determines your test version. If you cannot find the notice, or the date is close to October 20, 2025 and you are unsure, confirm your version with USCIS or your attorney or accredited representative before you start studying.
