Visa Cambodia

To enter Cambodia, a visa is required and your passport must be valid at least more than 6 months from the departure date from Cambodia.
The "visa on arrival" option in Cambodia is quite easy and widespread. With a valid passport, a passport size photo 4x6 cm, a completed application form and $ 20 in cash, you will see your visa (tourist 1 month) affixed for 5-10 minutes at international airports (Phnom Penh and Siem Reap ), as well as land border gates (with Vietnam, Thailand) without the need for any formalities.
