Do Dual Citizens Need a Cambodia Visa? Which Passport US-Dual Travelers Should Use
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.
Do dual citizens need a Cambodia visa, and which passport should they use?
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.

Dual citizenship does not skip the visa — it just changes which passport you use
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.
Do dual citizens actually need a Cambodia visa?
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.

الأسئلة الشائعة
Do dual citizens need a Cambodia visa?
Yes. Holding two passports does not exempt you from a Cambodia eVisa — every air traveler needs one. The only decision dual citizenship adds is which passport you apply on, because Cambodia reads your nationality from that single passport. The eVisa is single entry, valid for 3 months from issue, and lets you stay 30 days.
Which passport should a US dual citizen use for the Cambodia eVisa?
For most US-dual travelers the US passport is the cleanest choice: 10-year validity that easily clears the 6-month requirement, a plainly romanized name that maps directly onto the application, and an easy match between the form and the machine-readable zone. Apply on your second passport only if it genuinely solves a problem — your US passport is expiring, the name reads more cleanly on the other one, or onward travel works better on it.
Can I apply on one passport and travel on the other?
No. The passport you apply on is the passport you must board with and present at Cambodian Immigration. Your eVisa is tied to one passport number, and if you hand over a different passport at check-in, the airline sees no valid visa and will not board you — at the US departure gate, before you ever reach Cambodia. One passport, end to end.
What happens if I show up with the wrong passport at the airport?
The check-in or gate agent scans the passport you hand over and checks it against the visa attached to your booking. If your eVisa is tied to a different passport, the system shows no valid Cambodia visa and you will be denied boarding. This is caught in the United States, not in Cambodia, because the airline carries the liability for boarding a passenger without the correct documents.
My two passports show my name slightly differently. Which name do I use?
Use the exact name as printed on the passport you will carry, character for character against its machine-readable zone. Do not blend the two passports. Because the application and the passport you present are the same document, the name only has to match itself — so apply in the name on the passport your eVisa will be tied to, and carry that passport.
Does a second citizenship change the visa price or processing time?
No. 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 only determines which passport the visa is attached to — it does not unlock a different fee or a faster lane.
