2 Things British Travellers Must Have to Travel to Cambodia: Visa and e-Arrival Card

Two documents, two different jobs

A lot of British travellers arrive at the planning stage of a Cambodia trip thinking there is one form to fill in. There are two. The first is a visa, because UK passport holders are not visa-exempt for Cambodia. The second is the Cambodia e-Arrival Card, which every traveller flying into the country has to file, whatever their nationality and whatever visa they hold.

They are easy to confuse because both are done online, both arrive by email and both involve a QR code. But they do different jobs, they are filed at different times and neither one replaces the other. If you only remember one thing from this guide, make it this: the visa is permission to come in, and the e-Arrival Card is the declaration you make on the way in.

Thing 1: a Cambodian visa

British passport holders need a visa for any stay in Cambodia. Most holidaymakers use the Type T tourist visa, which allows a 30-day stay from the date you enter and is valid for 90 days from the date it is issued, so you can apply comfortably before you travel. If you are going for meetings, conferences or other work-related visits, the Type E business visa is the one to choose.

You can get the visa as an eVisa before you leave, or as a visa on arrival at the airport. The eVisa is the simpler option for most UK travellers. You arrive with it already approved, you skip the visa desk queue after a long-haul flight, and you know before you board that everything is in order.

Through us, you can apply for the Cambodia eVisa online for $80 USD (Tourist) or $90 USD (Business), approved in 3–5 days and delivered by email. We do not need a photo. If you hold a British passport other than a full British citizen passport, check the eligibility checker first.

For everything else about the visa itself, including extensions and visa on arrival, see our full guide to the Cambodia visa for UK citizens.

Thing 2: the Cambodia e-Arrival Card

The e-Arrival Card is Cambodia’s online arrival form. It replaced three bits of paper that used to be handed out on the plane, the immigration card, the health form and the customs declaration, with a single online submission. It has been the standard way to arrive by air since 2024.

Every traveller files their own card, including travellers who already have a visa. It asks for your passport details, the flight that lands in Cambodia, your arrival airport, your departure date and next destination, where you are staying, and a short set of health and customs questions. When you submit it, you get a QR code, and that QR code is what Immigration scans when you land.
