Earlier this month USCIS updated its policy guidance related to the naturalization civics test, increasing the general number of questions from 100 to 128, the number of exam questions from 10 to 20, and the number of correct answers needed to pass from 6 to 12. The new guidance allows the Interviewing Officers to ask all 20 test questions, even if the applicants achieve a passing score. This new policy will be effective on December 1, 2020, and applies prospectively to naturalization applications filed on or after that date. The passing score remains at 60%. The one exception to the new civics test is that applicants who are 65 or older and have been a lawful permanent resident for at least 20 years, can take a 10-question test and must answer 6 questions correctly in order to pass.
