On the day of your appointment, you must bring your application and any other needed paperwork. You must also send in your fingerprints and either one or two photos of yourself (the number varies depending on the country). No matter what, the photos you send must follow the same rules for Schengen visa photos. You may also be asked to go to an interview for a Schengen visa. Depending on the country, you may have to go to the embassy or consulate for the interview or finish the interview at the visa application center. The interview is short, and the main point is to find out why you want to go to that Schengen country. You might be asked about your trip, how long you plan to stay if you're going to see family or friends, etc. The point of the interview is to find out if you only want to visit the Schengen area, so try to be calm and answer the questions as truthfully as possible.
