Indonesia offers free-visa travel for several new citizenships, but you have to enter the country through the following ports: Airports Jakarta, Medan, Batam, Bali and Surabaya and seaports Batam Center (Batam), Sekupang (Batam), Sri Bintan Pura (Tanjung Pinang) and Tanjung Uban.
So visitors entering Indonesia on other international airports or seaports have to still purchase UDS 35 visa-on-arrival for 30 days. Visa-on-arrival can be extended two times up to 90 days where free-visa cannot be extended. You can depart Indonesia through any airport or seaport no matter what kind of visa you have (this changed in September 2015). Manado is not (yet) among free-visa entry points so all visitors entering Indonesia in Manado must get either 30 days visa-on-arrival for 35 USD or 60 days tourist visa that can be applied through Indonesian embassies around the world (price varies).
Citizens of 15 countries (Brunei, Cambodia, Chile, Ecuador, Hong Kong, Laos, Macau, Malaysia, Morocco, Myanmar, Peru, Philippines, Singapore, Thailand and Vietnam) who wish to enter Indonesia for the purpose of governmental duties, education, socio-culture, tourism, business, journalistic or transit can do so without visa through all air, sea or land crossing points since several years ago.
For nationals of 30 more countries (Austria, Bahrain, Belgium, Britain, Canada, China, the Czech Republic, Denmark, Finland, France, Germany, Hungary, Italy, Japan, Kuwait, Mexico, the Netherlands, New Zealand, Norway, Oman, Poland, Qatar, Russia, South Africa, South Korea, Spain, Sweden, Switzerland, the United Arab Emirate and the United States) visa requirements were waived as stipulated by the Presidential Decree No. 69/2015 and they are eligible to enter and remain in Indonesia without a visa for 30 days.
