Each US minor needs their own Cambodia eVisa, and the document set is the same five items adults upload — built per child. Here is exactly what to gather for a baby, a toddler, and a teenager, and why the consent letter you are worrying about is not on the visa form.

A US minor needs the same five items an adult does, gathered per child: the child US passport (valid at least 6 months from your date of entry with a clean page), a recent passport-style photo of the child, a clear scan of the child passport bio page, an email address (a parent address is fine), and a payment method. There is no notarized parental consent letter on the eVisa form, no family or group application, and no child discount — each minor applies on their own passport for their own $80 USD Tourist eVisa, approved in 3 business days and delivered as a printable PDF by email.
A US minor needs exactly the same five-item document set as an adult applicant — the difference is that you build one complete set for each child rather than one for the whole family. There is no family or group application and no shared file, so a baby, a toddler, and a teenager each get their own passport, their own photo, their own bio-page scan, and their own submitted form. If you are still mapping out the whole trip, our overview of the Cambodia visa for US citizens covers the rules that apply to every traveler in your party. The good news for parents: nothing on a child file is harder to gather than an adult one, and most of it you already have on hand.
The single thing that genuinely surprises American families is what is NOT on the list. Parents arrive expecting to upload a notarized parental consent letter, a birth certificate, or proof of the relationship to the child. None of that is part of the Cambodia eVisa form. The application is identity and payment, per person — who is this child, can we see their face, and who is paying. Everything heavier is either irrelevant to the eVisa or collected later through a separate step.
This guide walks through each document for a minor in the order the form asks for it, the child-passport lead time that catches families out, the baby-photo trick that saves a flagged file, and the consent-letter question every parent asks. When you are ready you can apply for each child, and our guide on whether children need a Cambodia visa at all covers the age rule behind the requirement.
Five items per child. Three you assemble from documents you already hold, two you set up at the application. Here is the full list in form order, with the specifics Cambodian Immigration enforces and the small slips that bounce a child file back to your inbox for a fix.
Each minor needs their own current US passport — there is no traveling on a parent passport, and there has not been for decades. It must have at least 6 months of validity remaining from your planned date of entry into Cambodia, plus at least one clean page for the entry stamp. Check the expiry on every child, not just the adults: US passports for minors under 16 are valid for only 5 years, so a passport issued three years ago may be closer to expiry than you think, and a short-dated child passport stops the whole family at the US departure gate.
A recent passport-style photo of the child against a plain white or off-white background, face fully visible, head centered, eyes open, neutral expression. The adult rules apply to babies too: no smile, no pacifier, no toy in frame, no glasses or hat, and crucially no parent hand or arm visible holding the child. JPEG file, under 2 MB, ideally 600×600 pixels or larger. This is the single most common reason a child file loses a day, and almost always for a fixable reason — a hand in shot, a closed eye, or an off-white wall.

The last three are quick. A clear scan or photo of the child passport bio page — both edges in frame, no glare on the laminate, every line of the machine-readable zone legible. A working email address, which can be a parent Gmail or Outlook account that accepts PDF attachments, since the approval letter is a PDF. And a payment method — Visa, Mastercard, AmEx, PayPal, Apple Pay, or Google Pay — which can be the same family card used for every child. If you want the same five-item breakdown written for adult travelers, the documents required for Americans guide covers it field by field.
This is where the Cambodia eVisa surprises American parents most. The documents families brace to provide for a child crossing a border are simply not part of the application. The list of what you do NOT upload is longer than the list of what you do.
The consent letter deserves a clear word, because it is the question we get most from parents. A notarized consent letter from the absent parent can be requested by an airline at check-in, or by an immigration officer, when a child travels without both parents — that is a real and separate situation. It is just not a Cambodia eVisa requirement. If only one parent is flying with the child, prepare a consent letter for the airline and the border anyway, but understand it has nothing to do with what you upload on the visa form. The US State Department travel guidance for Cambodia is the right reference for the airline and border side of traveling with a minor.
Of all five documents, the child passport is the one that can derail a trip, because it is the only one with a lead time you cannot compress at the last minute. The eVisa itself takes 3 business days; a child passport can take weeks. If a minor in your family does not have a current US passport, that is the very first thing to start — long before you think about the visa.
US passports for minors under 16 carry two complications adults do not face. They are valid for only 5 years rather than 10, and they require consent from both parents or guardians, which in practice usually means both appearing in person at the application appointment. For a newborn, you are often waiting on the birth certificate before you can even apply, which adds time on the front end. Families planning a Cambodia trip around a new baby should start the passport the moment the birth certificate arrives, not the month before the flight.
Routine US passport processing in 2026 runs several weeks, and the validity headroom matters as much as the passport existing at all. A child passport needs the same 6 months of remaining validity from your date of entry that an adult one does, plus a clean page for the entry stamp. Because the 5-year child passport ages faster against that 6-month rule, the most common family surprise is a parent passport that is fine and a child passport that is three months short. Lay all the passports out together and check each expiry before you book anything.
The child photo is the part of the file most likely to need a second attempt, because the specs that apply to an adult apply to a six-month-old: plain white background, face fully visible, head centered, eyes open, neutral expression, and absolutely no parent hand or arm in frame. You do not need a studio or a booth — a phone camera and a plain white surface produce a compliant photo every time once you know the routine.
For an infant who cannot sit or hold their head up, the trick most US parents use is to lay the baby on their back on a plain white sheet or blanket and shoot straight down from directly above. That keeps the background clean and removes any need to prop the child up with a visible hand. Use daylight from a side window rather than the camera flash, which bounces and creates harsh shadows. Take a dozen shots and pick the one where the eyes are open and the expression is calm — that single frame is usually the whole battle.
For a toddler or young child who can sit up, stand them against a plain white wall or sit them in a white-covered high chair, get down to their eye level, and use the phone rear camera. No toy in the shot, no pacifier, no smile if you can manage it — a neutral or calm expression is what the validator wants. Do not filter or beautify the image; the auto-flagger rejects heavily smoothed photos. Our dedicated guide on the Cambodia eVisa photo for babies and children walks through every angle and lighting setup in detail.
One detail that saves families a flagged file across the board: the name and date of birth on each child eVisa must match that child passport machine-readable zone exactly. It is genuinely easy to transpose two children, or fat-finger a baby date of birth, when you are filling several forms back to back. Check each completed form against the right passport before you submit. A mismatch is a free fix, but it costs a day you may not want to lose right before a flight.
The eVisa is only one of the two things every air arrival needs in 2026. The second is the Cambodia e-Arrival Card, and it applies to children exactly as it applies to adults. Every family member who flies in — babies included — needs their own e-Arrival record, with 14 fields covering the passport, the flight, and where you are staying, submitted within 7 days before you land.
A young child obviously cannot complete their own e-Arrival, so a parent fills it in on their behalf, one record per child. The details on each child record have to match that child eVisa and passport precisely — same name, same passport number, same date of birth. A single date-format slip on a child record is one of the most common reasons a family gets held at the kiosk while everyone behind them waits, so it is worth getting each one verified before you travel rather than rushing all of them at the airport with a tired toddler in tow.
At Immigration, each child is processed individually with their own passport, eVisa PDF, and e-Arrival record. Phnom Penh now flies through Techo International Airport (KTI), which replaced the old airport in September 2025, so make sure each family e-Arrival reflects the airport you actually land at. Have every child printed PDF in hand alongside the passports — children do not get a fast lane, and a complete file for each one keeps the family moving through the counter together.

No consent letter, no birth certificate, no proof of relationship on the form. Each child applies on their own passport for their own $80 USD Tourist eVisa, approved in 3 business days. Our breakdown of Cambodia visa cost for US families works the per-child budgeting through if you are pricing a larger group.
Two reminders before you start. First, sort every child passport early — that is the long-lead item, not the visa, and the 5-year child passport ages faster against the 6-month rule than you expect. Second, the e-Arrival Card is separate from the eVisa and applies to each child for every air arrival. If you are applying for several kids in one sitting, the guide on the Cambodia eVisa for kids and families covers the multi-child workflow from the same device.
Next steps for US families: confirm every child passport is in date with a clean page, take a clean white-background photo for each child, capture each bio-page scan without glare, then file one eVisa per child and one e-Arrival record per child inside the 7-day window. Get those pieces lined up for every traveler and the family clears Immigration together on arrival.
