what is the best way to extend visa on arrival in Indonesia. I will have 30 days visa on arrival (25 USD) and I need more 30 days without leaving country. It's possible to extend visa right after you get VOA?
I have never tried to get my visa extended in Indonesia. Take this is a disclaimer, then, for this what I know from a mix of personal experience and what I've heard from other travellers.
A lot of fanfare was made in 2009-2010 when it was announced that VOAs would be made extendable. Technically, the visa-on-arrival is extendable for 30 days in addition to the initial 30 days by visiting a local immigration office - as the Indonesian Ministry of Foreign Affairs website states. However, the Embassy of Indonesia in UK website makes adds a note:
The official website of the Indonesian Tourism Board also states the same. On searching online, it appears other people like this guy - who has an Indonesian wife - could list her as a sponsor and got the visa extended. Others, however, weren't as successful (search Lonely Planet's Thorn Tree).
To further confuse matters, my Indonesian VOA stamps all state 'Valid for 1 time only. Not extendable.' There aren't multiple categories of VOA, as far as I know, so I don't know why it says this.
My advice would be that it's just a lot less hassle to get a 60-day tourist visa by applying at your local embassy / consulate. The less you have to deal with local Imigrasi - from what I've heard of experiences from other travellers there - the better for you.
It will probably be cheaper for you too. For VOA, they accept payments in US dollars and Indonesian rupiah. The first time I went to Indonesia I made the mistake of not carrying any USD, only rupiah. The published rate for visa fees in rupiah turns out to be around $3-4 higher - so I ended up paying more. You'll pay in rupiah at local immigration offices for the extension which means you'll get the same lousy exchange rate instead of the $25. So paying for the 60-day tourist visa in your own country (roughly $45, depending on country) is going to be cheaper, not to mention less hassle compared to getting it in Indonesia.
