Most of the time the person who will interview you will be an immigration officer.
What should I expect?
You will be ask to take an oath which is simple. You will say your promise to tell the truth. The officer will verify your identity so bring a picture ID passport, driver's license and state ID card.
One question that will be ask is why you are applying for asylum? So, go to your interview with the correct paper work and be prepared to answer questions about your situation and your country. Good luck.
