A formal personal interview is not always mandatory for a Slovakia Visit Visa. However, all applicants are required to appear in person at the designated BLS International Visa Application Centre to submit their documents and provide biometric data, including fingerprints and a photograph. In certain cases, the visa authority may request an interview to clarify the purpose of your visit or to verify specific details in your application. It is important to be well-prepared with all relevant documents and clear answers regarding your travel plans at the time of your appointment.
