The Cambodia Business eVisa (Type-E) takes about ten minutes to apply for online — the same short form as the Tourist eVisa, with no sponsor letter, employment contract, or company invitation required. $90 USD all-in, approved in 3 business days, delivered as a printable PDF by email. Here is every step for US citizens.
US citizens apply for the Cambodia Business eVisa (Type-E) online in about ten minutes. Select the Business visa class, then upload five items: a US passport with at least 6 months validity, a plain-white-background passport-style photo, a clear scan of your passport bio page, a working email address, and a payment method. There is no sponsor letter, employment contract, or company invitation to provide. The fee is $90 USD all-in, the visa is approved in 3 business days, and it arrives as a printable PDF by email. The application is the same short form as the Tourist eVisa — the only practical difference is choosing Type-E at the start.
Most US travelers expect a business visa to mean paperwork — an invitation letter on company letterhead, an employment contract, a sponsor signature from a registered Cambodian entity, maybe a notarized this-or-that. The Cambodia Business eVisa asks for none of it. The application is the same five-item online form as the Tourist eVisa, and the only practical difference between the two is which visa class you select on the first screen.
That makes the Business eVisa one of the easiest business visas in Southeast Asia for Americans to apply for. You do not need a Cambodian company backing you, you do not need to prove a meeting is booked, and you do not need to show a return flight or a hotel reservation. Cambodian Immigration treats the visa-fee transaction as the commitment and handles the rest of the arrival picture through the separate e-Arrival Card in the week before you travel. The whole upload step runs about ten minutes if your passport and a fresh photo are on the same device.
This guide walks through every step of the Business eVisa application for US citizens in 2026 — what to have ready, how to fill each field, what to check before you pay, and what lands in your inbox afterward. If you are still deciding whether you need the Business class at all, the Cambodia Business visa Type-E guide for US citizens lays out exactly who needs it, and the general step-by-step eVisa walkthrough covers the Tourist flow if your trip is pure leisure. For the umbrella reference on cost, documents, and processing, see the Cambodia visa for United States citizens hub.
On the first screen choose the Business visa class, not Tourist — visa-class conversion is not supported inside Cambodia.
Type your name, passport number, and expiry exactly as printed on the bio page to avoid a machine-readable-zone mismatch.
Add a plain-white-background passport-style photo and a clear scan of your passport bio page.
Enter your arrival date and airport (KTI, SAI, or KOS); the date is not binding since the eVisa is valid 3 months from issue.
Check every field against your passport, then pay the $90 USD all-in fee by card or wallet and submit.
The Business eVisa is approved in 3 business days and arrives as a printable PDF by email.
Gather these five items before you open the application. Having them on the same device you are applying from — phone or laptop — turns a stop-start session into a clean ten-minute run. Three of the five you almost certainly already have; the other two take a couple of minutes to sort at a window.
Notice what is not on that list: no sponsor letter, no employment contract, no company invitation, no return flight, no hotel booking, no bank statement. The Business eVisa application pack is identical to the Tourist one. The Cambodia Business eVisa documents guide for Americans goes deeper on why the corporate-paperwork myth keeps circulating and what Immigration actually checks at the desk.
Here is the full sequence in the order the form asks for it. The single step that matters most for a business trip is the first one — choosing the right visa class. Get that right and the rest is straightforward data entry.
On the first screen, choose Business eVisa (Type-E), not Tourist (Type-T). This is the field US travelers most often get wrong, and it matters because visa-class conversion is not supported once you are inside Cambodia. If you select Tourist and only realize later, you cannot upgrade the existing visa — you would apply fresh on the correct class. Pick Type-E at the start if your trip touches meetings, paid work, a conference, a supplier visit, or any stay longer than 30 days.
Type your full name, passport number, date of birth, nationality, and passport expiry exactly as they appear on your passport bio page — character for character, including middle names if they are printed there. The most common avoidable rejection on a Business eVisa is a name that does not match the machine-readable zone. If your passport reads "JONATHAN," do not shorten it to "JON." Select United States as nationality and the United States as the issuing country.
Upload the white-background photo first, then the bio-page scan. The uploader auto-checks the photo for the usual flags — a smile, glasses, a colored or off-white wall, shadows behind the head, or resolution under 600 pixels will bounce it on the spot. The bio-page scan needs both edges in frame with no glare; tilt the passport a few degrees if the laminate is reflecting the light. Leave a thumb-width of margin around all four edges so nothing is cropped.
Enter your intended arrival date and the airport you are flying into. The open airports for US arrivals are KTI (Phnom Penh — the new Techo International Airport, which replaced the old PNH on 9 September 2025), SAI (Siem Reap-Angkor), and KOS (Sihanoukville). The arrival date does not lock you to that exact day — the eVisa is valid for 3 months from issue. For the intended address, a hotel name and city is enough; no booking reference is required.
Review every field against your passport one last time before you pay — this is the cheapest moment to catch a typo. The fee is $90 USD all-in for the Business eVisa. Pay with Visa, Mastercard, American Express, PayPal, Apple Pay, or Google Pay, then submit. You will get an immediate confirmation that the application is in the queue, with a reference you can use to check status.
Once the application is in, the Business eVisa is approved in 3 business days and delivered as a printable PDF by email. Business days are the operative words — applications submitted on a Friday afternoon or over a weekend start their clock on the next working day, and Cambodian public holidays such as Khmer New Year in April and Pchum Ben in the fall extend the window. If your trip is close, build in that buffer rather than betting on a same-day turnaround.
If Immigration flags something — a photo that slipped past the uploader, a bio-page corner that is soft, a name that needs a second look — you get an email explaining exactly what to re-upload. There is free resubmission if Immigration flags a correction, so a flagged file does not cost you anything beyond the time to fix it, and the 3-business-day clock keeps running once you reply. US-timezone support means questions get answered in your working hours rather than overnight.
When the approval lands, print two copies of the PDF — one for entry, one for exit — and keep a copy on your phone as a backup. Do not rely on a phone screen alone; print copies are what gets presented at the desk. If your inbox is still quiet on day three, give it until the next business morning before worrying, and reply fast to any correction email so the clock keeps running.
After more than 1,500 Business eVisa applications, the same handful of slips account for nearly every avoidable delay. None are hard to dodge once you know the list — and four of the five happen before you ever click submit.
The pattern across all five is that they are catchable before payment. A two-minute review of the form against your passport, the photo against the spec, and the card against your bank app prevents almost every flagged file. The broader Cambodia eVisa application mistakes guide for Americans runs through the full list, including the ones specific to longer business trips and family group filings.
The Business eVisa is $90 USD all-in — there is no separate government surcharge to add at the airport, no hidden processing line, and free resubmission if Immigration flags a correction. The initial stay is 30 days from arrival, identical to the Tourist eVisa. The difference is the extension: the Business eVisa is the only Cambodia visa you can extend in-country, in 1, 3, 6, or 12-month lengths, arranged through a Cambodian immigration agent once you have arrived.
That extension path is the reason most digital nomads, long-stay travelers, and Americans on extended work trips choose the Business class even when their first 30 days look like a normal trip. You apply once, online, before you fly — and the option to stay longer is already baked in. If you know up front that your stay will run past 30 days, the extension is lodged after arrival, not as part of this application.
For the full price picture, the Cambodia Business eVisa cost breakdown for Americans lays out the $90 USD all-in fee against the in-country extension fees so you can budget the whole trip rather than just the visa. If you are paying on a company card or expensing the fee, the Business eVisa company-card payment guide for Americans covers how that works at checkout and what shows on the receipt.

All seven Thailand–Cambodia land borders have been closed since June 2025, so in 2026 the only way for Americans to get from Thailand into Cambodia is to fly. Here is how the Bangkok-to-Siem Reap and Bangkok-to-Phnom Penh routes work, the Cambodia eVisa you need before you board, and why the old Poipet overland plan no longer exists.
Three ways to cover the 195 miles between Cambodia’s capital and Angkor Wat: a $15 express bus, a 45-minute flight, or a slow river ferry. Here is what each one actually costs an American traveler, how long it takes, and which one fits your trip.
