Interview preparation tips

  • 3Review your application before the interview: know the dates, addresses, and facts you submitted.
  • 4Bring your spouse or family members named in your petition if requested on your notice.
  • 5Answer questions honestly and concisely. Don't volunteer extra information not asked for.
  • 6If you don't understand a question, it's okay to ask the officer to repeat or clarify.
  • 7Don't guess. If you don't know something, say so. Don't make up an answer.
