现在申请入籍考的是2025版公民考试：题库128题、面谈问20题、答对12题才过关
美国公民及移民服务局（USCIS）的政策手册写明了现行入籍考试的版本分界：2025年10月20日当天或之后递交入籍申请的人，考的是2025版公民考试；在这之前递交的，仍考2008版。两版的通过线都是六成，但题量差了一倍，正在准备入籍的绿卡持有人，先按自己的递交日期对清版本，别背错题库。
2025版的题库共有128道题，涵盖美国政府、历史和地理常识，面谈时由移民官口头提问，最多问20题，答对12题即通过，答错累计9题即终止考试判定不合格，移民官会在达到通过或不合格时停下，不必问满20题。2008版的题库是100题，最多问10题、答对6题通过。对照之下，新版要准备的题更多，但通过比例没有变。
英语部分两版相同，考听说读写：说话能力在面谈问答中一并考察；阅读要从三句话里读对一句；写作要听写三句话中的一句并写对。第一次没考过还有一次补考机会，只补没过的部分。年龄和居住年限够格的人有减免：递交申请时年满50岁且以永久居民身份在美住满20年，或年满55岁且住满15年的，可以免考英语，但公民考试仍要考，可以用母语经口译进行；年满65岁且住满20年的，公民考试用专门标出的20道题里出10题，答对6题通过。
入籍的基本门槛也一并说清：年满18岁、持绿卡连续居住满5年（与美国公民结婚并共同生活的满3年）、期间实际在美时间不少于一半（5年制为30个月）、在递交申请的州或移民局辖区住满3个月、品行良好，最后宣誓效忠。USCIS 的公民资源中心免费提供两版考试的完整题库和学习材料，备考只认官方版本，不要买来路不明的题。（来源：美国公民及移民服务局）
Naturalization Applicants Now Take the 2025 Civics Test: 128 Questions in the Bank, 20 Asked, 12 Correct to Pass
U.S. Citizenship and Immigration Services (USCIS) sets the dividing line in its Policy Manual: anyone who files a naturalization application on or after October 20, 2025 takes the 2025 Naturalization Civics Test, while applicants who filed before that date take the 2008 test. The passing share is 60 percent under both versions, but the question bank doubles, so green card holders preparing now should first confirm which test their filing date puts them in.
The 2025 test draws on a bank of 128 questions on American government, history and civics. At the interview a USCIS officer administers the test orally, asking up to 20 questions; an applicant passes with at least 12 correct answers, and the officer stops once the applicant reaches 12 correct or accumulates nine incorrect answers, which fails the test. The 2008 test uses a bank of 100 questions, up to 10 asked, with six correct to pass.
The English test is the same under both versions and covers speaking, reading and writing: speaking is judged from the interview itself, reading requires reading one of three sentences correctly, and writing requires writing one of three dictated sentences correctly. An applicant who does not pass gets a second opportunity, retested only on the portions not passed. Age-based exceptions soften the requirements: applicants age 50 or older with 20 years as a permanent resident, or age 55 or older with 15 years, are exempt from the English requirement but must still take the civics test, which they may take in their language of choice through an interpreter. Applicants age 65 or older with 20 years of residence receive special consideration, a 10-question civics test drawn from 20 specially designated questions, with six correct to pass.
The underlying eligibility rules are unchanged: be at least 18, hold a green card with five years of continuous residence, or three years if married to and living with a U.S. citizen spouse, be physically present for at least half that period (30 months on the five-year track), live in the state or USCIS district of filing for at least three months, show good moral character, and take the oath of allegiance. USCIS publishes the full question banks and study materials for both tests free through its Citizenship Resource Center. (Source: U.S. Citizenship and Immigration Services)
