VTourist visas are valid for 30 days, your arrival day is counted as your first day, and you must leave the country on the 30th day. Tourist visas may only be extended due to natural disaster, illness or accident, and cannot be transferred to another type of visa. Visa on Arrival is usually not extendable and not convertible into other types of visa. Overstay visitors incur a penalty of US$20 per day for under 60 days over-stay. More than 60 days over-stay may incur a 5 (five) year prison sentence or a fine of IDR 25.000.000.
Your passport must be valid for a minimum of 6 (six) months from the date of entry into Indonesia. Please note that tourist visas do not apply to foreigners/expatriates (including members of their family) who are assigned/ based in Indonesia.
(You can get a 60 day visa in your home country (you have up to 3 months from date of application to enter Indonesia where you will then get your 60 day stamp) or at one of the countries close to Indonesia like Penang, Kuala Lumpur, Bangkok, Singapore. I have received 60 day visas from both Singapore and Penang in 2006 without any problems. Usually takes about 3 days and you will need a passport that has at least 12 months left on it, two passport photos, photocopy of the first page of your passport and money to pay for the 60 day visa.)
