إذا كنت تحمل جوازي سفر، فإن قاعدة تأشيرة كمبوديا الإلكترونية بسيطة: تقدم على جواز السفر الذي ستسلمه فعلياً لشركة الطيران وإدارة الهجرة الكمبودية، واستخدم نفس جواز السفر للدخول وبطاقة الوصول الإلكترونية والخروج. خلط جوازات السفر هو السبب الأكثر قابلية للتجنب الذي يجعل الأمريكيين ذوي الجنسيتين يتم رفضهم عند البوابة.

Apply for the Cambodia eVisa on the exact passport you will physically present to the airline and to Cambodian Immigration — and use that same passport for entry, the e-Arrival Card, and exit. The eVisa is electronically linked to the passport number you applied with, so the passport you hand over at the gate must be the same one. For most dual-national Americans, the US passport is the simplest choice: it usually has the longest validity, the airline expects it, and US citizens face no special Cambodia entry barrier. Whichever you choose, do not switch passports mid-trip — that mismatch is the most common avoidable reason dual nationals get stopped at the gate.
If you are an American who also holds a second passport — US and Ireland, US and Mexico, US and the Philippines, US and India, whatever the pairing — the Cambodia eVisa question feels more complicated than it is. There is one rule, and it covers every case: pick the passport you will physically present at the airport, apply for the eVisa on that exact passport, and then use that same passport for everything — boarding, the e-Arrival Card, the entry stamp, and the exit stamp.
Cambodia does not care that you hold a second nationality. The eVisa system reads exactly one passport: the one whose details you typed into the application. It does not see your other citizenship, it does not blend the two, and it does not give you options at the gate. The single thing that matters is that the passport in your hand when you land is the same passport your eVisa is built on. Get that right and dual citizenship is a non-issue. Get it wrong — apply on one passport, travel on the other — and you have manufactured a mismatch that Cambodian Immigration is fully entitled to turn back.
The reason there is only one rule comes down to how the eVisa is stored. When your Cambodia eVisa is approved, it is electronically bound to the passport number, nationality, and name you entered on the application. The PDF you print is just a human-readable copy of a record that, on the Cambodian side, points at one specific document. There is no field for "and also this other passport." The visa exists for the passport you applied on, and only that one.
That has a hard consequence at the gate. When you board, the airline checks that you hold a valid Cambodia eVisa for the passport you are traveling on. When you land, Cambodian Immigration scans the passport you present and matches it against the eVisa record. If the passport number, nationality, or name does not line up with what is on file, the eVisa does not resolve — and an officer can refuse entry until it is sorted, which for a single-entry visa with a printed PDF is not a quick fix at a busy arrivals hall.

Both passports get you into Cambodia on an eVisa — the choice is rarely about eligibility and almost always about which one keeps the rest of the trip frictionless. For most dual-national Americans, the US passport wins on practical grounds, and here is the reasoning rather than a blanket rule.

There are sensible reasons a dual national might choose the other passport instead — your US passport is within 6 months of expiry while the second one is fresh, or your flights are already booked on the non-US document, or your second nationality is the only one currently in your hand. All of those are fine. The rule does not say "always use the US passport." It says "apply on, and travel on, the same one." If the second passport is the one you will actually present, apply on that, and make it your single passport for the whole trip.

The single mistake that turns dual citizenship into a problem is using one passport to enter Cambodia and a different one to leave — or boarding on one and presenting the other at Immigration. It feels harmless. It is not. Cambodia stamps the passport you enter on, and the exit check expects to see that same stamped passport on the way out. Hand over the other one at departure and the officer finds no Cambodia entry stamp in it, which reads as someone who entered without being recorded.
The same logic applies the moment you board. If your eVisa is on your US passport but you instinctively hand the gate agent your second passport because it was on top in your bag, the airline cannot match a valid Cambodia eVisa to the document you presented, and they can deny boarding before you ever leave the US. Airlines are liable for carrying passengers who will be refused entry, so they check carefully — and a dual national flashing the wrong passport is precisely the case they are trained to catch.
The fix is a habit, not a document. From the moment you apply, decide which passport is your "travel passport" for this trip, and put the other one away. Book the flights on it. Apply for the eVisa on it. File the e-Arrival Card on it. Carry it in the same pocket every time you reach a counter. Leave the second passport zipped in your bag as backup only. If you never take it out at a checkpoint, you can never accidentally create the mismatch.

Plenty of dual nationals have passports that do not agree on the name. A US passport might read "JOHN ANTHONY REYES" while a Filipino passport reads "JOHN REYES SANTOS," with the maternal surname appended in the local convention. A US passport might Anglicize a name that the other country renders with diacritics or a different transliteration. None of this is a problem for Cambodia as long as you respect the one rule: the name on your eVisa application must match the passport you apply on, exactly as that passport prints it in the machine-readable zone.
So do not "harmonize" the two. Do not blend the US first name with the other passport surname because it looks more complete. Type the name precisely as it appears on the single passport you have chosen to travel on — same spelling, same order, same characters the scanner reads. The eVisa then matches that passport at the gate, and the existence of a differently-spelled name in your other passport is irrelevant because that passport never comes out of your bag.
Diacritics and special characters are worth a specific note. If your chosen passport shows accented letters or characters outside the basic Latin set, follow how that passport renders them in its machine-readable zone — that bottom strip uses a standardized substitution (for example, dropping accents), and matching the MRZ is what the system checks. When in doubt, copy the bottom MRZ lines rather than the decorative printed name at the top.

There is a second document in the 2026 entry process that catches dual nationals who got the eVisa right: the Cambodia e-Arrival Card. It is a separate, mandatory digital form for every air arrival, and it asks for your passport details just like the eVisa does. The card and the visa have to agree. If your eVisa is on your US passport but you fill the e-Arrival Card using your second passport — maybe because it was the one you grabbed — the kiosk sees two documents pointing at two different people, and that is a fast way to get sent back to a help desk.
Treat the e-Arrival Card as the same passport, second form. Whatever passport your eVisa is built on, that is the passport number, nationality, and name that goes on the 14-field card, submitted within the 7-day window before you fly. One passport drives the eVisa, the e-Arrival Card, the boarding pass, and the entry stamp. Keep them all on the same document and the dual-citizenship angle disappears entirely.
