Cambodia eVisa for Kids and Families: How Americans Apply for Children

How to apply for the whole family in one session

Four separate applications does not mean four separate trips through checkout. The efficient way to handle a family is to run every traveler back-to-back in a single session and pay once at the end. You complete the form for the first family member, add the next traveler, complete theirs, and keep going until everyone is in. The whole family settles at one checkout on one card, and the approved PDFs come back to the same email inbox.

Practically, that means gathering everything before you start. Have all four passports open to the bio page, all four photos saved as JPEGs on the same device, and one email address and one payment method ready. Working from a laptop with the passports stacked beside you is far smoother than thumbing through them on a phone. Most US parents finish a family of four in about 15 to 20 minutes once the photos are sorted — the photos are what take the time, not the form.

You can use one email address for the entire family. The approval PDFs all arrive in the same inbox, each clearly labeled with the traveler's name, so you are not chasing four separate accounts. Use an email you actually check and that accepts PDF attachments — a personal Gmail or Outlook account is ideal, since corporate inboxes that block attachments are a common way the approval letters get lost. If you want to see each form field before you start, our step-by-step guide to applying for the Cambodia eVisa online walks through the screens one at a time.

One payment covers everyone. You are not entering a card four times — the family total is charged once at a single checkout, billed in USD, so there is no currency math to do and no risk of one child's application being left half-paid. If a card is declined, nothing in the batch starts, so make sure your card is cleared for international online payments before you begin a family session.

What each child needs — the same five documents

A child's eVisa application asks for exactly the same five things an adult's does. There is no simplified kids' version and no relaxed standard for minors. The difference is purely logistical: a parent completes and submits the form on the child's behalf, but the documents belong to the child.

• A US passport in the child's own name. Infants and newborns need their own US passport before you can apply — there is no way to add a baby to a parent's book. US child passports are valid for 5 years and must be applied for in person with both parents present.
• A passport-style photo of the child. Same specs as an adult: plain white background, recent, neutral expression, no hats, head centered. This is the part parents find hardest, and it has its own section below.
• A clear scan or photo of the child's passport bio page — both edges visible, no glare on the laminate, all the printed text and the machine-readable zone legible.
• An email address. This can be the same one you use for the rest of the family; the approval PDF is labeled with the child's name.
• A payment method. Charged once for the whole family at checkout, so the child's fee is just part of the family total.

The passport requirement trips up families more than anything else. Your child needs at least 6 months of validity on their passport from the date you enter Cambodia, plus one full blank page for the entry stamp — and children's passports expire on a 5-year cycle, so a passport issued when your child was two is invalid by the time they are seven. Check every child's expiry date now, not the week before you fly. For the full document picture for under-18s, including the consent-letter question that comes up for solo-parent travel, see our guide to the Cambodia eVisa documents US families need for minors.

Use the child's name exactly as it appears in their passport machine-readable zone, character for character, including any middle name. Do not shorten "Alexander" to "Alex" or drop a hyphenated surname because it is long. A name on the application that does not match the passport is one of the most common reasons a child's file gets flagged for a correction.

The baby photo: how to get a compliant infant headshot

The hardest part of any family application is the passport-style photo of a baby or toddler. The specs do not bend for age: plain white background, face fully visible, eyes open where possible, head centered, neutral expression, no toys or hands in the frame, no pacifier, and ideally no one else visible holding the child. Getting a six-month-old to hold still and look at a camera with a neutral face is genuinely the most difficult ten minutes of the whole process.

The reliable method for infants: lay a plain white sheet or blanket flat on the floor or a bed, lay the baby on their back on it, and shoot straight down from directly above with your phone's rear camera. The white sheet becomes the background, and you avoid the shadow problem entirely. For a baby who cannot sit up, this overhead approach is far easier than trying to prop them against a wall. Make sure the blanket is smooth and genuinely white, not cream or patterned, and that no hands or arms creep into the frame.

For toddlers who can sit, set them against a plain white wall in a high chair or car seat pushed close to it, and get a second adult to crouch beside the camera to catch their attention — just not in the shot. Take a burst of twenty or thirty frames and pick the calmest one. A slightly open mouth is usually fine; a wide laugh, a cry, or a hand over the face is not. Daylight from a side window keeps the skin tones natural and the wall evenly lit.

Save the chosen frame as a JPEG, ideally 600 pixels or larger on the short side, and crop it to a square headshot with the child's face centered. Do not filter, smooth, or beautify it — the upload check looks for natural skin texture. If the photo is flagged, it is a free fix: you get an email telling you what to retake, the 3-business-day clock keeps running, and there is no second fee.

Every child needs their own e-Arrival Card too

The eVisa is only half the picture for air arrivals. Every traveler — including every child — also needs their own e-Arrival Card, the separate arrival declaration Cambodia requires before you land. Just like the visa, there is no family card: a family of four files four e-Arrival Cards, each with its own 14 fields, submitted within 7 days before your flight.

Each child's e-Arrival Card must match their eVisa and passport exactly — same name, same passport number, same date of birth. The cards capture the bigger arrival picture the visa skips: your flight details, where the family is staying, and the customs and health declaration. Because the window opens just 7 days out, file all four in one sitting once your flights are locked, rather than scrambling at the airport. A single mismatched date or a card missing for one child is a common reason families get held up at the kiosk.

Plan for the e-Arrival the same way you planned the visa — one per traveler, all done together. It is $5 USD per child, verified through us, with the same per-person pricing as adults. When you have flights booked and your approved eVisas in hand, get the whole family's e-Arrival Cards sorted in one pass so nobody is the missing card at the gate.

Putting the family trip together before you apply

Pull it together and the family workflow is straightforward. One eVisa per traveler, the same five documents for each child as for each adult, $80 USD per person, all approved in 3 business days and delivered as printable PDFs to one inbox. The only genuinely fiddly part is the baby photo, and an overhead shot against a white blanket solves that. Run the whole family in one session, pay once, and you are done in under twenty minutes.

Two reminders before you start. First, check every child's passport expiry today — children's US passports run on a 5-year cycle and need 6 months of validity from your entry date, and a renewal is not a same-week fix. Second, remember Phnom Penh now flies through Techo International Airport (KTI), which replaced the old airport in September 2025, so each child's e-Arrival Card should reflect the airport you actually land at.

Next steps for US families: confirm each child needs a visa, gather the four passports and four photos, apply for the whole family in one session when everything is in hand, and use the same inbox for all the approvals. Have each child's passport bio page and photo ready before you begin, and the family form moves quickly.
