During the naturalization interview, a USCIS Officer will ask you up to 10 civics questions from the list of 100. You must correctly answer six (6) questions to pass the civics portion of the naturalization test. Questions include things like What do we show loyalty to when we say the Pledge of Allegiance? Name one American Indian tribe in the United States. Name one of the two longest rivers in the United States. They seem fairly neutral to me. Are there any studies which show the civics portion of the naturalization test is biased?
