Visa on Arrival (VoA) in Indonesia allows eligible travelers to obtain a visa upon entering the country, typically at international airports or seaports. This visa is usually valid for 30 days and can be extended once for an additional 30 days. It’s available to citizens from several countries, and travelers must have a passport valid for at least six months, a return ticket, and sufficient funds for their stay. The VoA aims to simplify entry procedures and enhance tourism.
