No — a Cambodia eVisa is a single-use, single-entry document. Once you have entered Cambodia on it, it is spent, and a second trip needs a brand-new application. Here is exactly why, what your old approval is good for, and how the returning process works for Americans.
No. The Cambodia eVisa is a single-entry, single-use document. Once you have used it to enter Cambodia, it is spent — leaving the country closes it permanently, and a second trip requires a brand-new application. This is true even if the eVisa is still inside its 3-month validity window, because that window only ever authorized one entry. Your old approval letter stays useful as a record of your details and your prior trip, but it cannot get you back across the border. For your next visit, you apply again: a Tourist eVisa is $80 USD all-in, approved in 3 business days, and you file a fresh e-Arrival Card in the week before you fly.
You cannot reuse a Cambodia eVisa. It is single entry, single use — the moment you have been stamped into Cambodia on it, that visa has done its one job, and stepping back across the border to fly home closes it permanently. There is no carry-over, no second swipe, no leftover credit. Your next trip starts with a new application, full stop.
The reason this question comes up so often is that the eVisa looks reusable. It arrives as a clean PDF, it carries a 3-month validity date, and on a returning Americans desk like mine, that combination convinces a lot of people they are holding something they can dust off for trip number two. They are not. The 3-month window is the deadline to make a single arrival, not a season pass for repeat entries.
This guide explains exactly what your old eVisa is and is not good for, why single entry works the way it does, what to keep from your last trip, and how the returning application actually runs for Americans. When you are ready, you can apply for your next Cambodia eVisa in a few minutes, and our Cambodia visa for United States citizens hub pulls cost, documents, and timing into one place.
The Cambodia eVisa is issued as a single-entry document, and single entry is the whole reason you cannot reuse it. It authorizes exactly one crossing into Cambodia. When an immigration officer stamps you in, the visa is consumed against that entry. When you later leave — by air, by river, by the open Vietnam or Laos land crossings — the document is closed out. It does not reset, and it does not stay live for a return leg.
It helps to separate two dates that travelers often blur together. The validity window is 3 months from the date your eVisa is issued, and it tells you only how long you have to make your single arrival. The stay is 30 days, counted from the day you are stamped in. Neither of those numbers gives you a second entry. You could enter on day one of the 3-month window, leave a week later, and the remaining eleven weeks of validity are worthless for getting back in — the single entry it covered is already gone.
This also means there is no such thing as "saving" an unused stretch of validity for a future trip. If your plans changed and you never traveled at all, the eVisa simply expires at the 3-month mark, unused, and your next trip needs a new one anyway. The single entry is the unit of value here, not the calendar days around it.
If you fly to Cambodia regularly and the repeat-application rhythm is wearing on you, that is the signal to look at whether a multiple-entry route fits your travel pattern instead. The single vs multiple entry breakdown for Americans walks through when the math tips in favor of a multi-entry option and when sticking with a fresh single-entry eVisa each trip is still the cleaner call.
Your old eVisa PDF is not a travel document anymore, but do not delete it. It is a genuinely useful reference when you apply again, and a few of its details save you real time on the second pass.
What the old approval cannot do is bear repeating: it cannot get you into Cambodia a second time. Do not print it for your next trip expecting it to scan at the gate, and do not assume an officer will wave it through because it looks official. It is expired against its single entry the moment you used it. Treat it as a record, not a ticket.
If you want the fastest possible second application, the returning-applicant checklist for Americans turns those saved details into a step-by-step run — what to copy across, what changed since last time, and the small mismatches that slow a returning file down.
The good news for repeat travelers: a second Cambodia eVisa is the same light application you remember, and you already know the shape of it. There is no penalty for applying again, no "returning visitor" surcharge, and no limit on how many times you can hold a fresh single-entry eVisa over the years. Each trip is simply a new application against your current passport.
A single-entry eVisa is used up once you enter and leave; your next trip needs a brand-new application.

A new Tourist eVisa is $80 USD all-in, approved in 3 business days. A new Business eVisa is $90 USD all-in, also approved in 3 business days. Both are delivered as a printable PDF by email, both come with free resubmission if Immigration flags a correction, and both are backed by US-timezone support if a question comes up while you are sorting the trip. The required documents are the same five every time: your passport, a passport-style photo, a scan of your passport bio page, an email address, and a payment method.
The one thing that genuinely changes between trips is anything tied to your passport. If you renewed your US passport since your last visit, your eVisa must be issued against the new passport number — a visa tied to an expired book will not match the document you hand over at the desk. Same logic applies to a legal name change: apply in the exact name your current passport shows, not the name on your old approval.
A few things are also worth a quick refresher even for seasoned returners, because the rules around Cambodia entry have shifted recently. The tourist auto-extension ended in November 2025, the Phnom Penh airport is now Techo International (KTI), and all seven Thailand-Cambodia land borders have been closed since June 2025. The
After thousands of returning files, the same handful of errors come back again and again — and almost all of them trace to assuming the second trip works like the first did, only without the new application. Here is what catches repeat travelers out.
The biggest one is showing up at the airport with last trip's eVisa, convinced the 3-month validity means it is "still good." It is not. If you traveled on it, it is spent; if you never traveled and three months passed, it expired. Either way, an officer at the desk cannot use it to admit you, and you are now sorting a visa in the worst possible place to do it.
The second common slip is forgetting the e-Arrival Card entirely, because it felt like a one-time chore the first time around. It is not — the e-Arrival Card is required for every single air arrival, every trip, filed fresh within 7 days before each flight. There is no reusing the old one either. Our e-Arrival walkthrough for Americans covers all 14 fields if you need a refresher on what changed.
A third mistake is leaving the new application too late. A returning traveler who applied months ahead last time sometimes assumes a repeat is instant — it is not. Plan for the full 3 business days again, and add buffer if your trip is close. The application is fast, but it is not on-demand, and a tight connection plus a flagged photo is exactly the squeeze you do not want.
Finally, do not assume your last passport will do. Returning travelers who renewed in the gap between trips sometimes apply on muscle memory using the old number. If your passport changed, everything follows the new book — including the requirement to re-check that you still have at least 6 months of validity and a blank page. When that is settled, you can start your new application and have the PDF back inside 3 business days.
So, can you reuse a Cambodia eVisa? No — it is single entry, single use, and your next trip needs a fresh one. A new Tourist eVisa is $80 USD all-in, a Business eVisa is $90 USD all-in, both approved in 3 business days and delivered as a printable PDF by email. Keep your old approval as a reference, not a ticket. If you are doing this often, the new-visa-every-trip explainer for returning Americans lays out the rhythm of repeat applications in full.
One reminder before you book. The visa is one form and the e-Arrival Card is a different form, and both are mandatory for every air arrival — every trip, not just your first. The visa application happens now; the e-Arrival happens within 7 days before you fly. Returning Americans who plan for both at the start sail through the desk the same way they did last time.
