To enter Indonesia, your passport must be valid for more than 6 months. Members of 45 countries can obtain a free 30 day“Visa on Arrival” (VOA) at the airport. If you plan to stay longer, you can purchase an extendible VOA for $35. It can give you an additional 30 days to stay. Check with your local Indonesian Embassy to see if you are eligible for Visa on Arrival.
Currently, VOA is suspended for arrivals into Indonesia. We expect that this is reinstated in early 2022, so that tourists can again enter on a VOA.
