Naturalization Test

During the naturalization interview, a USCIS Officer will ask questions about an applicant's Form N-400, Application for Naturalization, and background. An applicant will also take an English and civics test unless he or she qualifies for an exemption or waiver. The English test has three components: reading, writing, and speaking. The civics test covers important U.S. history and government topics. See below to learn more about the test and the free study tools available to help your students prepare. 

Speaking Test
An applicant's ability to speak English will be determined by a USCIS Officer during the eligibility interview on Form N-400, Application for Naturalization.

Reading Test
An applicant must read aloud one out of three sentences correctly to demonstrate an ability to read in English. The Reading Test Vocabulary List (PDF, 185 KB) will help your students study for the English reading portion of the naturalization test. The content focuses on civics and history topics.

Writing Test
An applicant must write one out of three sentences correctly to demonstrate an ability to write in English. The Writing Test Vocabulary List (PDF, 181 KB) will help your students study for the English writing portion of the naturalization test. The content focuses on civics and history topics.

Civics Test
There are 100 civics questions on the naturalization test (PDF, 296 KB). During an applicant's naturalization interview, he or she will be asked up to 10 questions from the list of 100 questions. An applicant must answer correctly six of the 10 questions to pass the civics test.

Your students have two opportunities to take the English and civics tests per application. If they fail any portion of the test during their first interview, they will be retested on the portion of the test that they failed between 60 and 90 days from the date of their initial interview.
