• The applicant’s bank statement (preferably for the last 6 months)
• The detailed itinerary of the traveling days in the Schengen Zone, hotel reservations, or a formal invitation letter by a resident of a Schengen country.

Depending on the embassy/consulate that you will be applying to, they might require additional documents to assure the request and the information are genuine, as for example, some embassies/consulates require a certificate that proves you have no legal issues pending or a criminal record. As, you must personally hand the documentation at the previously made appointment (as usually it is required), the person in charge at the embassy/consulate will notify you if there is any additional documentation needed and the nature of that documentation.
