Das Feld für die Einreise auf Ihrer Kambodscha eVisa-Bewerbung sieht aus wie eine Falle, ist es aber nicht. Hier erfahren Sie genau, welchen Flughafen Sie als US-Bürger im Jahr 2026 auswählen sollten, warum die Wahl weniger wichtig ist als Sie denken, und den einen Fehler, der Sie tatsächlich eine Korrektur kostet.

Select the international airport where your flight first touches down in Cambodia. For most Americans that is Techo International near Phnom Penh (KTI), which replaced the old Phnom Penh airport on September 9, 2025. If you are flying straight into the temples, choose Siem Reap-Angkor International (SAI); for the southern coast, choose Sihanouk International (KOS). Do not select any Thailand land border — all seven have been closed since June 2025. The good news: this field is not a hard lock. Your eVisa is a single-entry document valid for three months from issue with a 30-day stay, and that holds whichever of the three listed airports you actually arrive through.
Somewhere in the middle of the Cambodia eVisa application, US citizens hit a dropdown asking for the port of entry — the airport or crossing where you will arrive in Cambodia. It is the field that makes people stop and second-guess. What if I pick the wrong one? What if my connection changes? What if I do not even have my flights booked yet? Take a breath. This is one of the lowest-stakes fields on the whole form, and once you see how it actually works, it takes ten seconds.
Here is the short version. The port-of-entry field tells Cambodian Immigration where to expect you, but your eVisa is not chained to that exact airport the way a flight booking is chained to a seat. The document is single-entry, valid for three months from the date it is issued, and good for a 30-day stay — and those terms travel with you to any of Cambodia's three international airports. The field exists for arrival logistics, not as a gate that slams shut if your itinerary shifts.
When the port-of-entry dropdown opens, you are looking for one of three international airports. These are the only air gateways that accept an eVisa for US citizens in 2026, and they map cleanly onto where most Americans are actually headed. Pick the one your inbound flight lands at first — not your final destination city, the first Cambodian airport your plane touches.
This is the right answer for the large majority of US travelers. If you are flying into the capital — for the city itself, for business, or as a hub before connecting onward to Siem Reap or the coast — Techo International is your port of entry. It opened on September 9, 2025 and took over all commercial traffic from the old Phnom Penh field. On the form it may appear as Phnom Penh, Techo, or Techo International, sometimes with the code KTI. They all mean the same airport. Choose it.
Choose this if your inbound flight lands directly in Siem Reap, the gateway to the Angkor temple complex. Plenty of Americans fly straight in here from a regional hub like Bangkok, Singapore, or Seoul and skip the capital entirely. If Angkor Wat at sunrise is the reason for the trip and your ticket says Siem Reap, this is your port of entry — not Phnom Penh.
Choose this if you are flying directly to Sihanoukville for the southern coast and the islands — Koh Rong, Koh Rong Sanloem, and the beach scene. Direct international service into KOS is thinner than the other two, so most coast-bound Americans actually arrive through Phnom Penh and continue by road or domestic hop. If that is you, select Phnom Penh / Techo International, because that is where you clear Immigration.

Erste Reise nach Kambodscha? Hier ist die ehrliche Checkliste für Erstbesucher aus Amerika — das Visum, die US-Dollar-Geldbesonderheit, die Sicherheitsrealität, die Impfungen, der Tempel-Kleidungsstil und wie die Ankunft am neuen Flughafen im Jahr 2026 tatsächlich aussieht.
Alle sieben Landgrenzen zwischen Thailand und Kambodscha sind seit Juni 2025 geschlossen, daher ist in 2026 der einzige Weg für Amerikaner, von Thailand nach Kambodscha zu gelangen, das Flugzeug. Hier erfahren Sie, wie die Routen Bangkok-nach-Siem Reap und Bangkok-nach-Phnom Penh funktionieren, welches Kambodscha eVisa Sie vor dem Boarding benötigen, und warum der alte Poipet-Überlandplan nicht mehr existiert.
Drei Möglichkeiten, die 310 Kilometer zwischen der Hauptstadt Kambodschas und Angkor Wat zurückzulegen: ein $15 Expressbus, ein 45-minütiger Flug oder eine langsame Flussfähre. Hier erfahren Sie, was jede Option für einen amerikanischen Reisenden tatsächlich kostet, wie lange sie dauert und welche zu Ihrer Reise passt.

The single most common point of confusion on this field is the airport-code change at Phnom Penh. On September 9, 2025, the old Phnom Penh International Airport closed to commercial flights and Techo International took over, carrying the new code KTI. If you booked your trip earlier — or you are reading older guides — you may still see the previous Phnom Penh code on your ticket or in your head. They point to the same place for practical purposes: the airport you will actually fly into is Techo International.
So if the eVisa dropdown shows Phnom Penh, Techo, Techo International, or the code KTI, that is the option to choose for any capital arrival. If you ever see an old Phnom Penh code lingering in a third-party booking tool, do not let it throw you — your flight has already been moved to the new field by your airline, and selecting Phnom Penh / Techo International on the eVisa form is correct. There is no separate option you are missing.

This is the question behind all the second-guessing, so here is the plain answer: no, the port-of-entry field is not a hard lock. Your eVisa is a single-entry document valid for three months from the date of issue, with a 30-day stay once you enter. Those terms are what govern your entry — not the precise airport you ticked weeks earlier on a dropdown. If you select Phnom Penh / Techo International and your plans later shift you to a direct Siem Reap flight, your eVisa is still a valid eVisa.
What the field really does is set an expectation for Cambodian Immigration about where you intend to arrive, and it keeps your record consistent across the visa and the arrival systems. The smart move is simply to pick the airport that matches your booked or most-likely first landing. You do not need confirmed flights to apply, and you do not need to obsess over getting it perfect — pick the airport that fits your plan today.

For all the worry about the port-of-entry dropdown, the field itself rarely causes a problem when you pick one of the three accepted airports. The mistake that genuinely costs US applicants a correction is different: selecting an entry point your eVisa cannot be used at, then building a whole trip around it. The classic 2026 version is choosing — or assuming — a Thailand land crossing.
Picture the plan: fly into Bangkok cheaply, take a bus or shared taxi east, cross into Cambodia by land, and ride on to Siem Reap. It was a popular budget route for years. In 2026 it does not work, because all seven Thailand-Cambodia land borders have been closed since June 2025. An eVisa will not get you across, the crossing is not a valid option on the form, and travelers who only discover this at the border lose far more than a form correction — they lose a travel day and a plan.
