简短回答:是的。您的柬埔寨电子签证和电子抵达卡是两份不同文件,承担不同职责,2026年入境的美国人需要同时携带两者。以下是它们为何不同、各自涵盖什么内容,以及在移民柜台如何配合的详细说明。

Yes. An approved Cambodia eVisa does not exempt you from the e-Arrival Card, and the two are not the same document. The eVisa is your permission to enter the country; the e-Arrival Card is a separate, mandatory pre-arrival declaration — 14 fields covering you, your trip, and your customs items — that every air arrival into Cambodia must complete in 2026. You file the eVisa weeks ahead, approved in 3 business days, and the e-Arrival Card within 7 days before you fly. At the immigration desk you present both: your printed eVisa PDF and your e-Arrival confirmation. Having one but not the other is exactly what gets American travelers pulled aside at the gate.
This guide walks through what each document actually does, why Cambodia keeps them separate, when you file each one, and what you physically present at the desk. If you are still working out whether you need a visa at all, start with the Cambodia visa for US citizens overview, then come back here for the e-Arrival half of the picture.
The eVisa is the legal authorization that lets you cross the border. It is tied to your passport number, valid for 3 months from issue, and gives you a single entry with a 30-day stay. You apply weeks ahead of your trip, it is approved in 3 business days, and it arrives as a printable PDF by email. The Tourist eVisa is $80 USD all-in and the Business eVisa is $90 USD. This is the document an airline checks before it lets you board a flight to Cambodia, and the document an immigration officer scans to confirm you are cleared to enter.
The e-Arrival Card is the digital version of the paper landing-and-customs slips Cambodia used to hand out on the plane. It is 14 fields across three sections — your personal and passport details, your trip and flight details, and a short customs and health declaration. It is filed within 7 days before you arrive, costs $5 USD verified through us, and produces a confirmation you show at the gate. It does not authorize entry on its own — it simply tells Immigration the details of who is walking up to the counter. Our guide on what the e-Arrival Card requires walks through every field if you want the full breakdown.

There is a practical upside for you in the split, too. Your visa is settled and off your mind weeks ahead, so the only thing left in the busy week before departure is a short 14-field form. It also means a flight change after you have your visa does not touch the visa at all — you simply update or refile the e-Arrival side. The two timelines barely overlap, which is why we treat

Do Americans need a visa? →The single most common mistake is treating the two as one task and trying to do both at the same time. If you complete the e-Arrival Card the moment your visa is approved — say, two months before your trip — it falls outside the 7-day window and you will have to file it again. Apply for the visa early; save the e-Arrival Card for the week of travel. If you want the full step-by-step on the visa half, our guide on how Americans apply for the Cambodia eVisa online covers it field by field.

What goes wrong is almost always one of the two documents missing or unverified. A traveler with a perfect eVisa but no e-Arrival Card gets sent to complete it on the spot, which in a busy arrivals hall can mean a long delay. A traveler with an e-Arrival confirmation but no valid visa does not board the flight in the first place. The fix is boring and reliable: file both, print both, and present both. The e-Arrival side is the cheaper of the two, and our breakdown of the e-Arrival Card fee for Americans covers exactly what that step costs and what you get for it.
If you are still unsure whether the e-Arrival Card applies to your specific trip — a connecting flight, a child traveling with you, a short layover that turns into an overnight — the canonical answer for US travelers lives in our do US citizens need the e-Arrival Card explainer. For every standard air arrival in 2026, though, the answer is the one this guide opened with: yes, you need both.
