Currently, citizens from 97 countries can get an Electronic Visa on Arrival (e-VOA) to visit Indonesia for the purposes of tourism, governmental duties, business talks, goods purchasing, participation in meetings, or transit.
The single-entry e-VOA is valid for 30 days and can be extended one time for 30 days online through the Indonesia Immigration official website or directly at the Immigration Office. This allows you to stay in Indonesia for a maximum of 60 days in total, after which you must leave the country.
