During your visa interview, a consular officer will determine whether you are qualified to receive a visa, and if so, which visa category is appropriate based on your purpose of travel.  You will need to establish that you meet the requirements under U.S. law to receive the category of visa for which you are applying.

Please keep in mind that the purpose of a face-to-face interview is to enable consular officers to assess your qualifications outside the scope of document review.  As such, we rarely review documents during an interview and rarely rely on documents to make visa decisions.
