柬埔寨不会要求您提供回程机票或银行余额证明来批准您的电子签证或盖章入境。问题出在更早一步——在美国离境口,航空公司(而非柬埔寨)可能会提出要求。以下是这条界限的具体位置。

No. Cambodia does not require US citizens to show an onward or return ticket, and it does not require you to prove a minimum bank balance or funds for the eVisa or at immigration. There is no onward-travel field on the eVisa application and no published proof-of-funds threshold. The one place the question can come up is the airline check-in counter at your US departure gate, where the carrier — not Cambodia — may ask about onward travel because they are liable if a destination refuses you. A confirmed Cambodia eVisa is the strongest answer to that question, because it shows you are already cleared to enter. You do not need a paid return flight or a printed bank statement to fly.
This guide separates the two cleanly: what Cambodia actually requires, what your airline might ask, and how a confirmed eVisa quietly answers most of it. If you want the wider entry picture first, the Cambodia visa requirements for US citizens checklist lays out the full set of conditions, our overview of the Cambodia entry requirements for US citizens covers what you face on arrival, and the complete Cambodia visa for United States citizens hub ties cost, documents, and timing together.
That is the part most US travelers find genuinely surprising: the application asks remarkably little. The Cambodia eVisa documents checklist for Americans spells out the full list of what you upload, and you will notice an onward ticket is nowhere on it. If you are weighing whether discretion could ever go against you, our guide to whether you can be denied entry to Cambodia walks through the real, narrow grounds.

The single best answer to a gate agent is a confirmed Cambodia eVisa. When you show that you already hold an approved visa for your destination, you have removed the airline’s core worry — that you will be turned away on arrival and become their problem. The eVisa is approved in 3 business days and delivered as a printable PDF by email, so you can have it in hand and on your phone well before you reach the airport. For the full picture of where you are actually allowed to land on that visa, the eligible entry points for US citizens guide covers every approved airport.

It is also worth knowing that there is genuinely no hidden funds hurdle built into the pricing. The eVisa is a flat, all-in figure — Tourist $80 USD, Business $90 USD — with no funds verification bolted on. Our breakdown of what is included in the Cambodia eVisa price for Americans shows exactly what that covers, and the no-hidden-fees explainer confirms there is nothing extra waiting at the border.

If a one-way ticket genuinely worries you, the cleanest fix is to make sure your eVisa is approved and in hand before you head to the airport — it does the reassuring for you. You can start your Cambodia eVisa application as soon as your passport is sorted, and there is free resubmission if Immigration flags a correction, plus US-timezone support if anything needs a second look.
