However we have recent reports (May 2017) that officials are charging USD for Visa on Arrival as well, so be prepared for that.If you are crossing from Thailand the situation is similar as with crossing into Laos, you will pay more if you buy your Visa on Arrival in Thai Baht (rate seems to be about 1600 Baht, approx. Usually, you can find someone running a side business exchanging USD, competition generally dictates the exchange rate.If you want to avoid the long lines & wait times, you can opt for an e-visa online, however, it’s a tad more expensive than on arrival.Hat Lek/ Ko Kong is the most convenient crossing if you’re heading to Sihanoukville in Cambodia from the Kho Chang region in Thailand but (but last I checked) you can’t enter using an e-visa at this boarder.If you like to plan ahead and not deal with the stress of getting a visa on arrival at the border, then an e-visa is perfect for you.Note tho, it can take at least 3 days to process the application so applying the night before entry is not an option, also the e-visa can only be used at certain ports of entry.

You can also get a fast boat along the Mekong River to Phnom Penh, however, it’s much more expensive.Your e-visa will give you 3 months (starting from the date of issue) to enter Cambodia and allows you to stay for up to 30 days, with the option of extending your visa.It’s slightly more expensive than a visa on arrival costing you USD opposed to USD.These problems do not generally exist with arrival into airports.To get a tuk tuk from the Cambodian boarder to Kho Khong should cost between 92,000- 120,00 Cambodian Riel.
