A travel consent letter is a signed letter from a student's parents or legal guardians confirming that the student has permission to travel abroad with named teachers or group leaders. For most school trips, it is not a legal requirement. However, border officers, airline staff and immigration officials can still ask for one whenever a minor travels without their parents, and a few countries do make it mandatory. Therefore, every student who is a minor should carry one.
What Is a Travel Consent Letter and Why Do School Groups Need One?
A travel consent letter is written permission from a parent or guardian for their child to travel internationally with another adult. In the words of Daniel Casey, Beyond Classrooms' Chief Operations Officer, it "shows authorities that the minor student is allowed to be traveling with the teacher/guardian who is currently with them."
The letter exists for child abduction prevention. As the US government's guidance on travel documents for children puts it, "ports of entry in many countries have security measures to prevent international child abduction." A group of teenagers arriving in a new country with adults who are not their parents is exactly the situation those measures are designed to check.
When Is a Consent Letter Required and When Is It Only Recommended?
A travel consent letter is recommended for every school trip abroad but required only by some countries, depending on the destination and the students' nationalities. Daniel is direct about the odds: "We always recommend a travel consent letter. But in 99% of cases, it is not required."
The other 1% is why every student should carry one. In Daniel's experience, that is the moment "when customs officials are concerned that a minor may be unauthorizedly traveling with an adult."
Government guidance follows the same pattern:
Canada says a consent letter is not legally required but may be requested by immigration authorities and airlines, and specifically recommends one for a child traveling with a school group.
The United States does not require proof of both parents' permission for a minor to travel internationally, but the State Department's advice on traveling with minors notes that some countries require a notarized permission letter when a child travels with someone other than a parent.
Mongolia is an example of a country that requires a letter. The State Department's Mongolia country information page states that minors traveling with guardians who are not their parents must carry a signed, notarized letter from their parents.
For international schools, nationality is as important as the destination. A single class at an international school can hold passports from several countries, and the rules that apply at a border can differ for each. Collecting one letter per student for every trip is simpler and safer than working out which students on which trip strictly need one.
The same applies to groups joining our school trips in the United States. US border officers can ask who a minor is traveling with, and a signed letter answers that question immediately.
Who Should Sign When Students Travel With Teachers Instead of Parents?
The student's parents or legal guardians sign the letter, never the school or the teachers. "Parents should always sign and authorize their students to travel with a teacher or guardian," Daniel says. The teachers appear in the letter as the named accompanying adults.
When possible, both parents should sign. The US government's travel documents guidance advises that when a child travels with a guardian, both parents should sign the letter. Canada's guidance asks for a signature from each parent or person with decision-making responsibility for the child.
Two situations need extra care:
Separated or divorced parents. If one parent has sole custody, the State Department notes that proof of sole legal custody may be needed in place of the other parent's signature. In this case, attach a copy of the custody document to the letter.
A parent who cannot be reached. If one parent is unavailable to sign, start early. A letter with one signature where two are expected is the kind of gap that could prompt questions at a border.
The letter should also name all the accompanying teachers, not only the lead teacher. That way, if the lead teacher falls ill or the group splits across two flights, each student is still traveling with an adult the letter names.
What Should a School Trip Consent Letter Include?
A school trip consent letter should identify the student, the trip and the accompanying adults clearly enough that an official who has never heard of the school can check it in under a minute. Daniel's short version: "the student's name, where they are traveling to, the reason, and the name of the adult who will be with them when they travel."
A complete letter covers:
The student’s information: full name exactly as it appears on their passport, date of birth, nationality and passport number
The parents or guardians: full names, home address, phone number and email
The trip: destination countries (including any transit countries), departure and return dates, and flight numbers if known
The reason: the school's name and the trip's purpose, for example a service learning program or a curriculum-linked study trip
The accompanying adults: full names of the lead teacher and other accompanying teachers, with a contact number for the trip
A clear statement of consent: the US government suggests wording such as "I acknowledge that my child is traveling outside the country with [the name of the adult] with my permission."
Signatures and date: from each parent or guardian, with a witness or notary stamp
The US government guidance also states a preference for letters written in English. Canada notes that there is no official format, so a clear one-page letter is better than a long one.
One page is enough: an official should be able to match the student, the trip and the teacher at a glance.
Does a Travel Consent Letter Need to Be Notarized?
A travel consent letter does not always need to be notarized, but notarization is the safest standard and some countries, including Mongolia, require it. "Often, a local notary public is sufficient," Daniel says.
Canada's guidance allows any adult to witness the signature but says a notary is "strongly recommended." The US government guidance also states a preference for a notarized letter. A notary's stamp gives officials something independent to check, which a parent's signature alone cannot offer.
Two practical points are easy to overlook:
Originals beat copies. Canada warns that border officials may not accept photocopies or digital versions. The lead teacher should carry the signed originals, with scans held as a backup.
Notaries take time. Parents may need an appointment to get the letter notarized, so set the deadline for signed letters weeks before departure, not days.
How Is a Consent Letter Different From a Permission Slip or Medical Consent Form?
A travel consent letter is for border and immigration officials, a permission slip is for the school, and a medical consent form is for the people providing care. "They really are quite similar!" Daniel acknowledges.
| Document | Who reads it | What it does |
|---|---|---|
| Travel consent letter | Border officers, immigration officials, airline staff | Proves the student has permission to travel abroad with the named adults |
| School permission slip | The school | Records that parents agree to the trip, its cost and the code of conduct |
| Medical consent and information form | Trip leaders, teachers, medical staff | Lists conditions, allergies and medication, and authorizes treatment |
Keep the travel consent letter as its own page, separate from the other two forms. An official at a border wants the travel permission, not three pages of medical history.
How Does Beyond Classrooms Handle Pre-Departure Paperwork?
Beyond Classrooms provides every school with a travel consent letter template and follows up until the signed letters are in. "We provide a template travel consent letter and remind your team to get them to us prior to travel, for both the teachers' sake and ours," Daniel says.
The consent letter is one part of a wider pre-departure process included in the standard program fee:
A pre-departure pack for each program, covering the itinerary, accommodation, a packing list, entry requirements and in-country emergency contacts.
Entry requirement reminders, such as passport validity and arrival forms. Thailand, for example, requires all foreign visitors to complete a Thailand Digital Arrival Card online within three days before arrival.
A student risk review, using the medical, dietary and personal information schools share, so leaders can prepare an individual safety response for each student. The full process is on our school trip safety page.
Copies for the local team, so the program leader who meets the group on arrival holds the same documents as the teachers.
For supervision ratios, rooming and timelines, see our guide to planning travel and accommodation for large student groups.
What Should Schools Check Before Departure Day?
Before departure day, schools should confirm that every student has a signed letter, that the lead teacher holds the originals, and that the local guides have copies.
A final checklist for the week before travel:
One signed consent letter for every student, with names and dates matching their passports and travel documents exactly
Notarized letters for any destination or nationality that requires them, checked against the relevant government or embassy page
Custody documents attached where only one parent has signed
Originals in the lead teacher's carry-on bag, not checked luggage
Scans shared with the local guide and the trip provider, and saved somewhere the teachers can access them offline
Passports, visas and arrival forms completed for every student
School permission slips completed and collected by the school
Medical and dietary information shared, and medication packed in carry-on luggage
Local guides hold copies of every consent letter, so the documents travel with the group from the moment it lands.
A travel consent letter is a small step that helps a school trip run smoothly. The team at Beyond Classrooms is happy to assist with the process, from sharing the template to following up on signed letters, so students and schools are well prepared before departure.
