N-400 Test Questions: 2026 Civics Study Guide
Practice N-400 test questions for the naturalization civics interview. Covers all 100 official USCIS questions on US history, government, and rights.
N-400 Test Questions: What to Expect
The civics test is the most nerve-wracking part of the naturalization interview for many applicants. You've done the paperwork, you've waited months for your interview date, and now you're sitting across from a USCIS officer who's about to ask you questions about American history and government—in English.
Here's the good news: the questions aren't a surprise. USCIS publishes all 100 official civics questions in advance. The officer will ask you up to 10 of those 100 questions during your N-400 interview. You need to answer at least 6 correctly to pass. If you don't pass on the first attempt, USCIS gives you a second chance 60-90 days later.
This guide covers the topics you'll encounter in the N-400 test questions, provides sample questions across each category, and explains what the officer expects when you answer. You don't need to recite memorized text word-for-word—USCIS officers accept equivalent correct answers.
American Government: Structure and Principles
Roughly a third of the 100 civics questions cover how the US government is structured and operates. These are often the most manageable questions because the structure is clear and consistent:
The three branches of government is the most fundamental concept. The legislative branch (Congress) makes laws, the executive branch (led by the President) enforces laws, and the judicial branch (headed by the Supreme Court) interprets laws. Almost every exam applicant gets asked about this—know it cold.
Congress structure: Congress has two chambers—the Senate and the House of Representatives. The Senate has 100 senators (2 from each state), who serve 6-year terms. The House has 435 representatives, who serve 2-year terms. The number of House representatives per state depends on population.
The President's role: The President is the Commander in Chief of the military, signs or vetoes legislation, appoints federal judges and Cabinet members (with Senate approval), and leads the executive branch. Joe Biden was the 46th President; Donald Trump became the 47th in January 2025.
The Supreme Court: There are currently 9 justices on the Supreme Court. The Chief Justice leads the court—John Roberts currently holds that position. Justices are appointed by the President and confirmed by the Senate, and they serve lifetime appointments.
Constitutional amendments: Several amendments come up regularly. The First Amendment guarantees freedoms of religion, speech, press, assembly, and petition. The 19th Amendment gave women the right to vote. The 13th Amendment abolished slavery. The 14th Amendment established birthright citizenship. The 26th Amendment set the voting age at 18.
American History
History questions cover events and people from colonial times through the 20th century. These are often what applicants find hardest to remember, especially if US history wasn't part of their schooling. Here are the highest-priority topics:
Colonial and founding period: Christopher Columbus arrived in America in 1492. The original 13 colonies declared independence from Britain on July 4, 1776. The Declaration of Independence was primarily written by Thomas Jefferson. The Constitutional Convention took place in 1787 in Philadelphia.
The Civil War: The Civil War was fought from 1861 to 1865. Abraham Lincoln was President during the Civil War. The Emancipation Proclamation freed enslaved people in Confederate states. The Union (North) defeated the Confederacy (South).
World wars: The US entered World War I in 1917 (and it ended in 1918). World War II started for the US after the Japanese attack on Pearl Harbor on December 7, 1941. General Dwight D. Eisenhower was the Supreme Commander of Allied forces in Europe; he later became the 34th President.
Civil rights: The civil rights movement fought against racial discrimination and segregation. Key figures include Martin Luther King Jr., Rosa Parks, and Thurgood Marshall. Brown v. Board of Education (1954) declared school segregation unconstitutional. The Civil Rights Act of 1964 and Voting Rights Act of 1965 were landmark legislation.
Geography and Symbols
Geography and symbol questions are usually the easiest category for most applicants. The key facts:
States and geography: There are 50 states. The capital of the United States is Washington, D.C. The United States has 50 stars on its flag (one for each state) and 13 stripes (one for each of the original colonies). Alaska and Hawaii are the two states that don't share a border with any other US state.
National symbols and holidays: The national anthem is "The Star-Spangled Banner," written by Francis Scott Key after the Battle of Baltimore in 1814. Independence Day is July 4th. Memorial Day honors US military personnel who have died in service. Thanksgiving is celebrated on the fourth Thursday of November.
The Statue of Liberty: It's located on Liberty Island in New York Harbor. France gave it to the United States as a symbol of friendship. It represents freedom and democracy.
Rights and Responsibilities
A portion of the civics questions addresses the rights and responsibilities of US citizens and residents. These questions are particularly meaningful for naturalization applicants because they describe your future status as a citizen.
Rights guaranteed to everyone in the US (citizens and non-citizens): freedom of speech, freedom of religion, freedom of the press, freedom to peacefully assemble, and the right to petition the government.
Rights for US citizens only: The right to vote in federal elections and the right to run for federal office are restricted to US citizens. Citizens can also bring family members to live in the US more easily than non-citizens and are eligible for federal jobs that require citizenship.
Responsibilities of citizens: Serve on a jury when called, vote, pay taxes, defend the country if needed, and obey the laws. These aren't optional suggestions—they're part of what citizenship means.
How the Civics Interview Works
The N-400 civics test is an oral interview, not a written test. The officer will ask you questions and you answer aloud. Here's what that looks like in practice:
The officer chooses 10 questions from the 100 official questions. They ask them one at a time. You answer each one before they move to the next. As soon as you've answered 6 correctly, you pass—the officer stops asking questions and moves on.
The officer isn't trying to trick you. If your answer is essentially correct but slightly imprecise in wording, most officers accept it. For example, the question "What is the supreme law of the land?" has the official answer "the Constitution," but saying "the US Constitution" or "our Constitution" is equally acceptable.
What happens if you fail? The officer will inform you at the end of the interview. USCIS schedules a second interview 60-90 days later, and you retake only the parts you failed (civics, English, or both). If you fail the second attempt, USCIS denies your application and you'd need to start over.
English Language Test
The civics test isn't the only test at the N-400 interview. You'll also be tested on your English reading, writing, and speaking ability—unless you qualify for an exemption.
Speaking: The officer evaluates your English throughout the entire interview, not in a separate section. Your ability to understand and respond to questions during the application review is the speaking test.
Reading: You'll be asked to read one sentence from a set of options. The sentences are taken from USCIS's official reading vocabulary list, which contains words like "Congress," "right," "President," "freedom," and "citizen."
Writing: You'll write one sentence that the officer dictates. The sentence comes from USCIS's official writing vocabulary list. You need to write it legibly and correctly enough to demonstrate understanding—minor spelling errors may be acceptable.
Exemptions from the English test exist for applicants who are 50+ with 20 years of permanent residency, 55+ with 15 years, or who have a qualifying disability documented on Form N-648. These applicants can take the civics test in their native language through an interpreter.
Tips for Studying the 100 Civics Questions
A hundred questions sounds like a lot. In practice, many are easier than expected—and they cluster into logical groups that make studying more efficient.
Group the questions by topic. Government structure questions (what are the three branches? who makes federal laws? how many senators are there?) are heavily interconnected. Once you understand the system, individual questions answer themselves. History questions require more memorization but follow chronological patterns that create natural sequences.
Practice out loud every day. Civics knowledge in your head doesn't automatically translate to fluent spoken answers under interview pressure. Say your answers aloud during study sessions. If you have a family member or friend who can quiz you, that's even better—it simulates the interview format.
Understand, don't just memorize. "What is the economic system of the United States?" (capitalist economy, market economy) makes more sense if you understand what capitalism means, not just because you memorized the answer. Questions you understand are questions you won't forget under pressure.
Focus extra attention on current questions. Some civics questions change based on current officeholders: who is the President, who is the Vice President, who is the Governor of your state, who are your US Senators. Make sure your answers are current as of your interview date—these change with elections.
Don't cram the night before. Consistent study over weeks is more effective than an overnight marathon. If you've studied regularly for two or three months, you're almost certainly ready. The night before, review current-official answers and get a good night's sleep.
