Visa on arrival at the aerport is for 1 month.... from ambassy is for 2 months..the price is around 25 US doll. in Thailand.. but as natasha said you can cross the boarderline and do it again in Kuala Lumpur...

you can get on the airport - after 3 monthas you have to cross the boder for a day and than get a new one. if your swiss, german or austrian you don't need a visa

cost of that visa is $25 but if you wanna stay longer than 30 days u shoud go to the embassy 'cause visa on arrival is not extendable.

You can get visa on arrival. I'm not sure about the cost. try the net on Indonesia's immigration law. they might publish it. Or checkout Travel Advisor's website. bon voyage!
