Every child flying to the United States under the Visa Waiver Program must hold an individual ESTA minors ESTA authorization, regardless of age. When only one parent travels along, CBP officers routinely ask for a notarized travel consent letter. This 2026 guide explains the full application process, consent letter templates, and what happens at the border.
TL;DR: ESTA is the US visa-waiver authorization for travelers from 41 eligible countries visiting the United States for up to 90 days. It costs $40, is valid for 2 years (or until passport expiry), and allows multiple short business or tourist visits. Apply online before booking flights — most approvals arrive within minutes via the official ESTA website.

Why Minors Need Their Own ESTA
The U.S. Department of Homeland Security treats every traveler individually. Infants, toddlers, and teenagers all need a separate ESTA minors application tied to their own machine-readable passport. Parents cannot fold a child into their own authorization.
CBP rejected 0.9% of minor ESTAs in 2025, often because parents re-used outdated passport numbers. So check the passport’s expiration date and photo page quality before you file.
Pro tip: Apply for your ESTA at least 72 hours before your flight. Although most decisions are instant, some applications require additional review — and your airline may deny boarding without an approved ESTA in their system.
Age Breakdown
| Age | ESTA Required | Consent Letter Typical |
|---|---|---|
| 0-2 | Yes | If one parent absent |
| 3-11 | Yes | Recommended |
| 12-17 | Yes | Strongly recommended |
| 18+ | Yes (adult) | Not required |
Travel Consent Letter Template
Most CBP officers accept a one-page letter containing: child’s full name and passport number, travel dates, destinations, name of accompanying adult, name and contact of absent parent, signature, and notary stamp. List both parents’ phone numbers and email addresses too.
CBP may also call absent parents to confirm consent. Keep both parents reachable during travel hours.
Divorced or Separated Parents
When parents are legally separated, the accompanying parent should carry a court custody order or a notarized travel authorization. The International Parental Kidnapping Crime Act applies here, and CBP can refuse entry if the paperwork looks incomplete. Single parents flying solo should pack several copies.
Unaccompanied Minors
Airlines require unaccompanied minor (UM) services for children under 15. In contrast, CBP treats the child as any other VWP traveler at primary inspection. Officers will still pull the child into secondary inspection to run an interview and confirm the pick-up adult. Airlines charge $150 one-way for UM processing.
Applying on Behalf of Minors
Parents complete the online form using the child’s biographical data. The paying cardholder counts as the applicant for accounting purposes only — that choice does not touch the authorization. The approval then stays valid for two years or until the child’s passport expires.
Passport Photos and Readability
Child passport photos must be compliant with ICAO standards. Babies under 6 months old often need several attempts to meet the eye-open, neutral-expression rules. Book the photo right after a nap for the calmest result.
What to Expect at US Immigration
CBP typically fingerprints children over 14 and photographs all travelers. The officer may ask the child a simple question (“Where are you going?” or “Who are you travelling with?”). Coach kids to answer politely and honestly.
Medical Records and Medications
Carry originals of prescribed medications in labeled pharmacy containers. Add a doctor’s letter for anything unusual — insulin, EpiPens, controlled substances. With the paperwork ready, TSA rarely questions medical items.
Frequently Asked Questions
Q: Does an infant need an ESTA?
A: Yes. Every VWP traveler, regardless of age, requires an individual approval.
Q: How much does a child ESTA cost in 2026?
A: $40.27, identical to the adult fee.
Q: Is a travel consent letter legally required?
A: Not by statute, but CBP routinely requests one and may delay admission without it.
Q: What if the absent parent is deceased?
A: Carry a certified death certificate in place of consent.
Q: Can grandparents travel with minors on ESTA?
A: Yes, with a consent letter from both legal parents and copies of their ID.
Q: Will the child face interview questions?
A: Occasionally yes, particularly if they are teenagers entering for summer camps.
Q: How long is a child ESTA valid?
A: Two years or until the child’s passport expires, whichever is earlier.
Airline Unaccompanied Minor Policies
Major carriers impose age-specific rules that operate alongside ESTA. Consequently, British Airways accepts unaccompanied minors aged 5-11 on direct flights only, at £85 each way. Lufthansa sets its window at ages 5-17 for the service, priced at €60. American, Delta, and United each charge $150, with a minimum age of 5.
Book the airline UM service well before the trip and keep the reservation number handy at both airports. CBP inspectors may ask for the UM paperwork even when a relative is there for pickup.
School Groups and Summer Camps
School and camp travel to the United States continues to grow. Thousands of European teenagers fly to New England camps each June. Every participant still needs an individual ESTA plus a consent letter from both legal guardians. Group organisers usually hand out a template letter.
At arrival, CBP may ask for the camp’s contact details. Carry confirmation emails, camp addresses, and a printed itinerary.
Sporting and Cultural Exchange Programs
Tennis academies, ballet intensives, and music conservatories regularly host VWP teenagers. Short programs under 90 days fit ESTA rules as long as the program is unpaid. Paid scholarships flip the activity into student status, which requires an F-1 visa. Check each program’s immigration guidance.
The U.S. Department of Homeland Security also enforces Student and Exchange Visitor Program (SEVP) compliance for longer programs.
Disney and Theme Park Planning
Disney World, Universal Studios, and SeaWorld host tens of thousands of minors daily. Pack wristband ID, park reservation QR codes, and parent phone numbers. Disney’s MyMagic+ integration stores dining and hotel reservations under the parent profile.
One ESTA covers multiple entries. A family visiting Orlando on one trip and Los Angeles later, within the same 2-year window, stays fully authorized.
Medical Emergencies and Pediatric Care
U.S. pediatric emergency rooms charge $300-$2,500 per visit without insurance. Travel insurance with pediatric coverage is non-negotiable. Keep vaccination records, the pediatrician letter, and a medication list in a ziplock inside your carry-on.
CBP officers may ask basic health questions. A minor cough is fine, but an undiagnosed fever can trigger referral to CDC-designated medical officers.
Return-Trip Documentation
Some countries require the return airline to verify that minors fly with authorized adults. European customs officers, in turn, sometimes ask at re-entry how long the U.S. stay lasted. Keep boarding passes and ESTA confirmations for at least three months after the trip. Digital copies in cloud storage make any future claim easier.

International Adoption and Custody Concerns
International adoptions and complex custody situations demand extensive documentation. CBP may request court orders, adoption decrees, and original birth certificates. Hague Convention cases carry their own notarization rules. Plan adoption-related travel well ahead and consult the adoption agency.
The U.S. Department of State keeps specialist officers at its embassies in Seoul, Bogotá, and Addis Ababa. Bring their contact details in your travel paperwork.
Pediatric Vaccinations and CDC Guidance
The CDC recommends standard pediatric vaccines — MMR, DTaP, polio — be up to date before international travel. After the measles outbreaks in 2024-2025, some airlines began asking about vaccination. Carrying immunization records (USA format or equivalent) cuts down on questions.
Some U.S. summer camps also require specific health declarations. Vaccination clinics in major cities — Passport Health, Minute Clinic — offer walk-in boosters for $50-$150. Travelers can top up on arrival if needed.
Phone Plans and Device Rules
Prepaid SIMs from T-Mobile and Mint Mobile are the easiest option for minors traveling with family. Unlimited talk, text, and 20 GB data plans run $30 for a month. Wi-Fi calling over hotel networks adds free calls back to Europe. Teenagers stay connected without a big bill.
Parental controls like Apple Screen Time and Google Family Link keep working internationally. Digital safety stays manageable on ESTA trips.
Preparing the Child’s Travel Consent Letter Step by Step
The consent letter is the document that U.S. Customs and Border Protection (CBP) officers ask to see most often when a minor arrives without both parents. A strong letter names the child, lists passport and ESTA details, identifies both parents with contact information, names the traveling adult, and states the exact dates of travel and the itinerary. It is signed, dated, and — where possible — notarized. Some families add a second certified translation if they come from a non-English-speaking country, and many embassies recommend apostille certification for added legal weight.
Keep at least one original signed copy in the accompanying adult’s hand-luggage and one scanned copy in the child’s documents folder. If only one parent accompanies the child, the other parent’s written consent, combined with a copy of the birth certificate, avoids questions about custody. In divorce or sole-custody situations, bring a translated court order. Officers rarely read every line, but they check quickly that the document exists and matches the passport names — a missing signature can still add hours to border processing.
Airport Procedures for Families Traveling with Minors
Families with children under 12 may use the dedicated family lanes at many U.S. airports of entry. Children under 14 are not fingerprinted under Automated Passport Control, and they can remain in strollers or on parents’ laps during primary inspection. Even so, each child must have a separate ESTA approval linked to their own passport — there is no family ESTA application. Keep each approval’s confirmation number written inside the child’s passport cover so it can be found fast under pressure.
Flight attendants on international arrivals often hand out CBP Declaration Form 6059B before landing. One form per family group is enough, but every traveler (including infants) must be listed. Carry a pen, a printed itinerary, and the hotel address. If you connect to a domestic flight in the same airport, remember that re-checking luggage after CBP and clearing TSA again takes longer with children; add 45 extra minutes to published connection times and you will rarely miss a flight.
