An extensive array of study materials for the U.S. citizenship tests is available at the U.S. Citizenship and Naturalization Services website. These include vocabulary flashcards for the English test and a complete list of questions that may be asked during the civics portion of the exam.
Also available on the USCIS website are several practice tests and instructional documents that help the learner understand what to expect during the English portion of the interview. A summary of the English words he needs to understand and pronounce correctly is provided, along with a document that demonstrates the different commands an interviewer might use, such as, "Sit here," or "Write this." Printable flashcards include images and a section in which the learner can practice writing words and using them in a sentence.
Free study materials for the civics portion of the test include a downloadable study booklet, a video, and a complete list of 100 questions, along with their answers, that an interviewer may ask during the naturalization interview. The site also provides several interactive practice tests that give the learner instant feedback when an answer is incorrect.
Yet another study guide for the civics portion of the citizenship test is Preparing for the Oath, which is available at the Smithsonian National Museum of American History website. This detailed manual covers various topics, including American history, structure of the U.S. government, important symbols and U.S. holidays, in video and written form. It also includes practice tests and definitions of important terms that learners need to know for the test.
