when you visit Bali Indonesia the Visitors from USA, Canada, UK, Australia, New Zealand, and most of Western Europe don't need a visa to enter Indonesia. Provided you have a ticket out of the country and your passport has at least six months validity at the time of your arrival, you'll be issued with a tourist card which is valid for a 60-day stay. Keep the card with your passport as you'll have to hand it back when you leave the country. It is good for 60 days, not two months, some travelers have been fined for overstaying by only a day or so. It is not possible to get an extension on a tourist visa, unless there is a medical emergency or you have to answer legal charges. There are visas, particularly a business visitor's visa, which may be valid for a longer period. The immigration office is in Denpasar. If you have to visit this office, make sure you wear your most respectable clothes.
