The straight answer on speed for US travelers

If you are searching "how fast can I get a Cambodia visa" with a trip coming up, here is the answer before anything else: about 3 business days. That is the realistic fastest you can get a Cambodia eVisa as a US citizen, and it is the same speed for everyone. There is no instant approval to click, no overnight tier to buy, and no express lane that gets you to the front of the line faster than the next traveler. Every application runs on the same clock and is approved in 3 business days.

That is faster than it sounds. Three business days beats the multi-day "expedited" turnarounds that some other countries charge Americans a premium for, and it is a fixed, predictable window rather than a vague "up to two weeks." The reason it cannot go faster is structural: approval is a back-end process, not a manual queue you can pay to skip. So the real question is not "how do I buy speed" — it is "how do I make sure my application uses the full 3 days cleanly instead of stretching into five."

This guide covers the realistic fastest timeline, why no instant or rush tier exists, the day-of-week and timezone tricks that quietly add a day, and the four free moves that keep you as fast as the system allows. If you want the full clock laid out hour by hour, our how long the Cambodia eVisa takes for Americans guide has the complete breakdown — and when your dates are firm, you can apply and have your eVisa approved in 3 business days.

The realistic fastest timeline: 3 business days

Three business days is not a best-case estimate or a marketing figure — it is the actual rate at which approvals come back for US applicants, Tourist and Business alike. When people imagine getting a visa "fast," they picture minutes or an hour. The Cambodia eVisa is not that, and no service can make it that. But against the way most visas work, 3 business days is genuinely quick, and it is consistent enough that you can plan a trip around it.

It is worth being clear about what those three days cover. The clock starts once your application is submitted and paid, and it ends when your approved eVisa lands in your inbox as a printable PDF. The Tourist eVisa and the Business eVisa run on the same 3-business-day window — paying the higher Business price does not make it slower, and there is nothing faster to buy on the Tourist side either. Validity is 3 months from issue, with a 30-day single-entry stay, so applying early never costs you anything; an approved eVisa simply sits ready until you travel.

The honest framing matters because the internet is full of "12-hour" and "instant" Cambodia visa claims aimed at exactly the panicked traveler reading this. Three business days is the real number, and a flat $80 USD Tourist or $90 USD Business price is the real cost, with free resubmission if Immigration flags a correction. Our Cambodia eVisa same-day and rush options for Americans guide breaks down what those rush promises actually deliver, which is usually the same 3-business-day outcome with a padded price tag.

Why there is no instant button or rush tier

A faster tier only exists when there is a slow default to escape. With some visas the standard wait is a week or two, so a paid express lane that cuts it to a few days is a real product worth selling. The Cambodia eVisa does not work that way. The standard turnaround is already 3 business days, and that is the speed at which the approval itself moves — there is no slower setting sitting behind it for a premium to leapfrog.

Because approval is a fixed process rather than a line you can jump, paying more does not move you anywhere. You would be buying a place at the front of a queue that everyone passes through at the same rate. That is why a straight-shooting application service quotes one flat number — Tourist $80 USD, Business $90 USD, both all-in — and does not dangle a "priority" add-on. There is nothing legitimate to sell on top of the standard timeline, so a transparent service does not invent one.

It also means the price you see is the price you pay. No surprise "urgent processing fee" appears once you enter a close travel date, because there is no urgent product behind it. Your eVisa is delivered as a printable PDF by email on the same 3-business-day timeline whether you apply six weeks out or four days out. If you want to read the difference between honest timing and inflated speed claims, our guide on whether the Cambodia eVisa is instant for Americans takes apart the "instant" myth directly.

What quietly adds a day (and how to avoid it)

If 3 business days is the floor, the things that stretch it out are almost always avoidable. The most common one is a misread of the calendar. Business days are working days on the Cambodian side — they exclude weekends, and they exclude Cambodian public holidays, not US ones. A Friday-afternoon application in the US does not get a head start over the weekend; its three working days run Monday, Tuesday, Wednesday, so it lands around Thursday the following week.

There is a timezone wrinkle that catches US applicants specifically. Cambodia runs 11 to 14 hours ahead of the continental United States depending on your time zone and the season. A Sunday-evening submission in California is already Monday in Cambodia, which works in your favor; a Tuesday-night submission in New York is already Wednesday over there, which quietly costs you a day if you were counting from your own calendar. When your departure is tight, count the three working days from the Cambodian date your application arrives on, not the date on your phone.

The other thing that adds a day is a bounce. A photo that gets auto-flagged, a passport scan with glare across the machine-readable zone, or a name that does not match your passport exactly all send the file back for a correction before the clock can finish. With free resubmission the clock keeps running rather than restarting, but a clean first submission is still faster than any fix. Cambodian holidays such as Khmer New Year in April or Pchum Ben in the fall are the seasonal version of the same trap — a holiday in the middle of your window adds a day, so apply earlier when one is coming up.

None of these are mysterious delays; they are predictable, and predictable means plannable. The fix is to apply on a working day with clean inputs and to count the calendar correctly. If you want to see realistic timelines mapped against specific departure dates, our last-minute Cambodia visa guide for US citizens runs the scenarios so you can tell whether your dates leave enough room before you book anything you cannot change.

The four moves that keep you as fast as the system allows

There is no rush button, but there are four real things that get you approved as fast as the Cambodia eVisa can move. None of them cost extra. They all come down to removing the friction that turns a clean 3-business-day approval into a five-day scramble of resubmissions.

• Apply the moment your dates are firm, on a working day if you can choose. A Monday-through-Wednesday application gives the 3-business-day clock its cleanest run before a following-week flight; a weekend application simply waits for the working week to begin.
• Get the photo and scan right the first time. A passport-style photo against a plain white background, a clear glare-free bio-page scan, and a name that matches your passport exactly are what keep the file from bouncing. A flagged photo is the single most common reason a US application loses a day.
• Use an email you actually check that accepts PDF attachments. The approval arrives as a PDF, and a corporate inbox that strips attachments is a classic trap — your eVisa is approved on time, but you cannot open it. A personal inbox avoids the problem entirely.
• Clear your card for international online payments before you start. A declined payment means the application never begins and the clock never starts, so a two-minute call to your bank up front can save the exact day you are trying to protect.

Do those four things and you are moving at the full speed the Cambodia eVisa allows, which is genuinely quick. The thing you cannot do is buy your way faster — so spend the energy on accuracy instead. If you have seen a "rush" price advertised and want to know what it actually buys, our guide on Cambodia rush eVisa cost and timing for Americans shows why the flat price and the 3-business-day window already give you the fastest honest outcome.

Putting it together before you apply

The whole picture in one line: the fastest a US citizen can get a Cambodia eVisa is 3 business days, the price is flat at $80 USD Tourist or $90 USD Business all-in, and every application is delivered as a printable PDF by email. There is no instant button and no rush tier — the speed lever is applying early on a working day with clean inputs, then counting working days on the Cambodian calendar. Three business days is already faster than most travelers expect.

One more step sits alongside the visa and trips up US air travelers who are focused only on speed: the Cambodia e-Arrival Card is a separate, mandatory form for every air arrival. It is not part of the visa and it has no effect on your 3-business-day approval. It is a short online form — 14 fields — that you submit within the 7 days before you fly. Plenty of Americans clear the visa cleanly, then forget the arrival card and get sent back to the queue at the airport kiosk. File both and the gate is a formality.
