When Applying for an F-1 Student Visa at a U.S. Embassy or Consulate Anticipate that the interview will be conducted in English.
Interviews are generally very brief.
Keep answers to the officer's questions short, but to the point. Organize your supporting documentation so that it can be logically presented without hesitation or fumbling through a briefcase. Do not take family members or friends with you to the interview. Do not state that you intend to work in the United States, even temporarily, after completing your studies. Be prepared to discuss what you expect to get out of your education.
