Capital City: Phnom Penh
Population: 16 million
Language: Khmer
Currency: Cambodia’s official currency is the riel (KHR). The US dollar is its secondary currency. ATMs dispense US dollars, and they are accepted everywhere, as long as they are newer bills in good condition. Small change will be returned in riel, as coins are not used. Prices may be quoted in either dollars or riel. Money can be changed at any bank. Be sure to have riel on hand when travelling to more rural regions, as the Cambodian riel is the primary currency used in the countryside.
Most visitors to Cambodia are eligible for a visa on arrival at Siem Reap or Phnom Penh International Airports as well as at land border crossings between Thailand, Laos, or Vietnam. A tourist visa on arrival is valid for a single entry of 30 days, and a one-time extension is possible. Most nationalities are also eligible to apply for a tourist e-Visa. It may be easiest to apply for a visa ahead of time at a Cambodian embassy outside of the country to avoid any hassle or misunderstanding at the border.
Most ASEAN nationals can stay in Cambodia visa-free for 14 or 30 days. All visa applications require a passport with six months validity and an empty page, as well as two passport photos. As travel policies change regularly, please check the official government website for the latest regulations before visiting.
