At the naturalization interview, a USCIS officer puts you under oath and goes through your Form N-400 with you, asking you to confirm or explain your answers and checking that you understand the yes/no questions. Every answer must be truthful and match your application and documents; if something has changed, say so. This is study help, not legal advice: if any answer is “yes” or you are unsure, talk to an accredited representative or an immigration attorney before your interview.
