Yes — dual citizens still need a Cambodia eVisa. The real question is which of your two passports to apply on, because that one choice decides your eVisa, your stamp, and whether you board the plane at all.

Yes. Holding two passports does not exempt you from a Cambodia eVisa — every air traveler needs one. The decision that matters is which passport you apply on, because Cambodia reads your nationality from that single passport and nothing else. Pick one, apply on it, travel on it, board on it, and present it at the airport. For most US-dual travelers the US passport is the cleanest pick — strong validity, a plain name field, and a tidy match between the application and the machine-readable zone. The only hard rule is consistency: the passport you applied with is the passport that has to be in your hand at the gate and at the Cambodian Immigration counter.
If you hold two passports, here is the short version: you still need a Cambodia eVisa, and the only real decision in front of you is which of your two passports to apply on. There is no dual-citizen exemption, no shortcut lane, no "I have a stronger passport so I can skip it." Cambodia issues the eVisa against one passport, reads your nationality from that passport, and expects to see the same passport again at the airport. Get that one choice right and the rest of the process is identical to any other traveler.
The mistakes dual citizens make almost never involve eligibility — they involve consistency. Someone applies on their US passport because the form was open in front of them, then packs their second passport because it was closer to the door, then tries to board on the wrong one. That mismatch is what gets caught, and it gets caught early: at the check-in desk in the United States, long before Cambodia ever sees you. So this guide is really about one thing — picking a passport and then never deviating from it.
Below we walk through whether dual citizens really need a visa, how to choose between your two passports, the consistency rule that ties the whole trip together, and the handful of edge cases that catch out US-dual travelers — name differences, expiring passports, and second citizenships that complicate the picture. If you want the baseline rules first, our guide on whether US citizens need a Cambodia visa covers the standard case, and the full Cambodia visa hub for United States citizens pulls cost, documents, and timing into one place.
Yes. There is no nationality that gets visa-free entry to Cambodia for tourism, so holding a second passport changes nothing about the requirement itself. Whether you carry a US passport plus a UK, Canadian, Mexican, Vietnamese, Filipino, Indian, or any other passport, you are arriving as a visa-required traveler and you need an approved eVisa in hand before you fly. The eVisa is single entry, valid for 3 months from issue, and lets you stay 30 days.
What people sometimes confuse is the idea that a "stronger" passport on a visa-free list somewhere else also works for Cambodia. It does not. Cambodia does not maintain a broad visa-free arrangement that any of your passports would slot into for tourism. The practical effect for a dual citizen is simple: you are not choosing whether to get a visa, you are choosing which passport to attach it to. Both of your passports lead to the same eVisa requirement — the only difference is which document number, name, and nationality end up printed on the approval.
This is also why the second-passport question is not about saving money or skipping steps. The Tourist eVisa is $80 USD all-in and the Business eVisa is $90 USD all-in regardless of which passport you apply on, both approved in 3 business days and delivered as a printable PDF by email. Your citizenship mix does not unlock a different price or a faster lane — it only determines which passport you build the application around.

The Cambodia eVisa system reads your nationality straight off the passport you apply with. It does not see your second citizenship, it does not ask about it, and it does not factor it in. So the choice comes down to which passport gives you the smoothest run from application to airport — and for the large majority of US-dual travelers, that is the US passport.
The US passport tends to win on three plain practicalities. First, validity: US passports are issued for 10 years, so they usually clear the 6-month validity requirement comfortably. Second, the name: a US passport carries your name in a clean, romanized form that maps directly onto the application fields and the machine-readable zone, with no transliteration ambiguity. Third, the match: when the name, number, and nationality on your application line up exactly with the passport you will carry, there is nothing for an airline agent or an Immigration officer to question.
There is no advantage to applying on a non-US passport unless it genuinely solves a problem — a US passport stuck in renewal, a name that reads more cleanly on the other document, or an onward-travel reason that outweighs everything else. Absent one of those, default to the US passport. It is the path with the fewest moving parts, and fewer moving parts is the entire game when the consequence of a mismatch is being turned away at the gate.
This is the rule that matters more than which passport you pick: the passport you apply on is the passport you travel on, board with, and present at Cambodian Immigration. One passport, from the application screen to the entry stamp. Dual citizens get into trouble not because they chose wrong, but because they switched halfway through.
Here is how the mismatch actually plays out. You apply on your US passport, so your eVisa is tied to your US passport number. At the US airport, the check-in agent scans the passport you hand over and checks it against the visa attached to your booking. If you hand over your second passport — the one with no eVisa linked to it — the system shows no valid visa for Cambodia, and the agent will not board you. This happens at the departure gate in the United States, not in Cambodia. The airline carries the liability for boarding someone without the right documents, so they are strict about it.
The fix is boring and total: carry the passport you applied with, and use only that passport at every checkpoint. Check-in, boarding, the eVisa, the e-Arrival card, and the Immigration counter in Cambodia all have to point at the same document number. If you want to use your second passport for a different leg of a multi-country trip, that is fine — just keep the Cambodia entry and exit entirely on the passport your eVisa is tied to. Our guide on the eVisa eligible entry points for US citizens covers exactly which airports your single-entry visa is valid at.
Before you book anything, decide your Cambodia passport and write the number down. Apply on it, enter your flight booking on it, fill the e-Arrival card with it, and physically separate it from your other passport in your travel wallet so you cannot grab the wrong one at the gate. The single most common dual-citizen slip is reaching for the closer passport on autopilot.
Most US-dual travelers fit the standard case cleanly — apply on the US passport, carry it, done. A few situations need a second look before you start, and all of them trace back to the same theme: making the application match the passport exactly.
Name differences are the most common complication. If your two passports show your name slightly differently — a maiden name on one, a middle name spelled out on the other, accents or extra characters on one but not the other — apply using the exact name as it appears on the passport you will carry, character for character against the machine-readable zone. Do not blend the two. The application name and the passport you present have to be the same document, so the name only has to match itself. If you are unsure how a difference will read, our guide on passport requirements for Americans explains what Immigration actually parses.
Expiring passports decide the choice for you. If your US passport is inside the 6-month validity window from your date of entry, you have two options: renew it before you travel, or apply on your second passport if that one has the validity. Whatever you choose, the passport with the eVisa attached must be valid for at least 6 months from entry and carry a full blank page. Do not apply on a passport you then plan to renew before the trip — the new passport will have a different number, and your eVisa will be tied to a document you no longer carry.
Some second citizenships add their own wrinkles. If your other passport is from a country that requires its citizens to enter or exit on that specific passport, or one that complicates onward travel, weigh that against the simplicity of the US passport for the Cambodia leg specifically. The Cambodia entry is self-contained: your eVisa, your boarding, and your stamp all live on one passport, and what your other government requires elsewhere does not change that. When in doubt, keep Cambodia on the US passport and handle the second-citizenship rules on the legs where they actually apply. For the broader picture, the dual-citizen passport guide for Americans drills into the specific country combinations.
One last edge case: a name that does not match across documents after a marriage or legal change. The name on your eVisa application must match your current passport exactly, so if your passport still shows your former name, apply in that name; if you have already updated the passport, apply in the new name. Never mix the two on a single application. Our guide on fixing a name mismatch on a US eVisa walks through how to correct it if you have already submitted with the wrong spelling.
