Cambodia Entry Requirements for US Citizens: Everything You Need at the Border

Requirement 4: you arrive by air, at an approved airport

This matters before you ever reach the airport, because you select your arrival point on both the eVisa and the e-Arrival Card. Pick the airport you are actually flying into, and keep it consistent across both documents — a mismatch between your eVisa and your Card is an avoidable hold at the desk. Our Cambodia eVisa eligible entry points for US citizens guide lists every approved airport and the field where you choose it.

What you do NOT need — and what Immigration can still ask

• No return or onward flight ticket to be approved for the eVisa — you can apply before you have booked your flights.
• No hotel booking. The forms ask for an intended address in Cambodia, but a hotel name and city is enough, with no confirmation PDF or nights-paid evidence.
• No bank statement or proof of funds at the application stage — there is no minimum balance, payslip, or employer letter required to get approved.
• No travel insurance proof. Insurance is sensible for any trip, but the eVisa never asks to see a policy.
• No itinerary or day-by-day plan, and no vaccination record at the eVisa stage for US travelers.

Here is the nuance, though: not required to be approved is not the same as never asked. A Cambodian Immigration officer keeps discretion at the border and can, on the day, ask to see proof of onward travel or evidence that you can support your stay. It is uncommon for straightforward tourist arrivals, but it is their right. The simple insurance is to have a return or onward booking and a working payment card you can show if asked — you do not upload them, you just keep them reachable on your phone. Our guide on onward ticket and proof of funds for US citizens covers when this actually comes up.
