The official guidance, with sources
- U.S. government guidance
- USAGov says a child traveling abroad alone, or with only one parent or legal guardian, may need a letter of consent, because many countries screen for international child abduction at the border.1
- When the child travels with one custodial parent, the letter comes from the other parent; when the child travels with a guardian or alone, USAGov says both parents should sign.1
- The wording USAGov suggests is: “I acknowledge that my child is traveling outside the country with [the name of the adult] with my permission.”1
- U.S. Customs and Border Protection notes that some countries require a letter of consent, sometimes notarized, for children arriving or leaving without both parents, and points travelers to the destination’s embassy or consulate.2
- For U.S. school, church, cultural or sports groups of children under 19 returning by land or sea from Canada or Mexico, CBP asks for a group letter on letterhead in which the supervising adult certifies having consent for each child.3
- USAGov advises a parent who often crosses a land border with a child to always carry permission from the other parent, and a parent with sole custody to carry a copy of the custody document.1
- Destination country rules
- Canada asks for a consent letter when the custody of a child under 18 is shared and the other parent or guardian is not on the trip, or when the adult is not the child’s parent or guardian.4
- The Canada Border Services Agency says the letter must include the full name, address and telephone number of the custodial parents or legal guardians.4
- For a child entering Canada with one parent, Immigration, Refugees and Citizenship Canada asks for a letter signed by the parent not traveling, with that parent’s address and phone and a photocopy of their signed passport or national ID.5
- Mexico requires its own SAM exit form, signed by a parent or guardian and stamped by migration authorities, when a Mexican child leaves Mexico without a parent or the person holding parental authority.6
- Mexico does not ask for the SAM form when the minor travels with both parents, with one of them or with a legal guardian.6
Questions about the travel consent letter
Does a child need a consent letter to travel with one parent?
Often, yes. USAGov says a child traveling alone or with only one parent or guardian may need a letter of consent, and U.S. Customs and Border Protection notes that certain countries require one. Border officers, airlines and the destination country can all ask for it.
With one parent on the trip, the parent staying home signs. With grandparents, a friend, a group leader or no adult at all, both parents sign. A parent with sole custody carries the custody papers instead of, or along with, a letter.1,2
Does a child travel consent letter have to be notarized?
USAGov calls a notarized letter in English the preferred form, and the Canada Border Services Agency recommends notarization to avoid delays. Canada’s immigration department adds that a permission letter for a child traveling with another adult does not need to be certified.
The reason Canada gives is authenticity: a notarized signature supports the letter if a border officer questions it.1,4,5
Does my child need a consent letter to travel to Mexico?
For entry, Mexico follows its own rules, so the Mexican consulate is the source to check. For leaving Mexico, a child who is a Mexican citizen and travels without a parent or the person with parental authority needs the SAM form, issued free by Mexico’s National Migration Institute; a notarized or court authorization also works. With one or both parents, the SAM form is not needed.
U.S. citizen children under 16 who cross into Mexico by land or sea and come back can use a birth certificate instead of a passport, while air travel takes a passport or a Trusted Traveler Program card. A consent letter from the absent parent still helps answer border questions on either side.1,6
What does Canada ask for when a child travels with one parent?
A letter of authorization from the parent who is not traveling, in English or French if possible, with that parent’s address and phone number and a photocopy of their signed passport or national ID, plus the child’s passport and a copy of the birth certificate.
Separated parents with shared custody bring copies of the custody documents; a parent with sole custody may sign alone and brings the custody decree. Officers may not ask, but Canada strongly recommends having the papers ready.4,5
What to have at hand
- The child’s full name and date of birth, as on the passport
- Your address and phone, and the other parent’s if both of you sign
- The traveling adult’s name, relationship to the child and phone
- Destination, departure and return dates, and where the child will stay
It is not a passport application and not a custody order. It does not replace a country’s own exit form, such as the SAM form Mexico requires for Mexican children leaving without a parent.
Frequently asked questions
What should a child travel consent letter say?
At minimum, the sentence USAGov suggests — that the child is traveling outside the country with a named adult with the parent’s permission — plus the child’s full name and date of birth, the trip dates and destination, and the full name, address and phone number of each parent or guardian, as Canada asks.1,4
