In most cases, a personal interview is not required for a Slovenia visa. Applicants usually need to visit the visa centre only to submit documents and give biometric data such as fingerprints and a photograph. However, in some cases, the embassy may request an interview if they need more information about your application. This depends on your travel history, documents, or any doubts about your application. It is important to provide clear and accurate information to reduce the chances of being called for an interview.
