U.S. Immigration: 2026 Rules For Minors Travelling From Canada To The U.S.

Families in Vancouver and across British Columbia often send children to the United States for school trips, sports tournaments, visits with relatives, or shared custody visits. Strict documentation rules exist at both the Canadian and U.S. borders are meant to prevent abductions and runaways, and to confirm that a child is travelling with proper consent.

As a result, U.S. immigration officials require documents showing that minors are travelling with the knowledge and consent of their parents or guardians. These principles still apply in 2026, but it is important to understand the latest expectations around passports, identification, and consent letters.

If you have questions about a minor’s travel in the context of a broader immigration or border issue, our Vancouver U.S. immigration lawyers can help you navigate the process. Contact Border Solutions Law Group today for legal help.

Who Counts As A “Minor” For Cross-Border Travel?

In Canada, a “minor” (or child) is generally someone under the age of majority, which is 18 or 19, depending on the province. In British Columbia, the age of majority is 19, so anyone under 19 is considered a minor.

Border officers also pay close attention to travellers who appear to be under 18, even if local laws treat 18-year-olds as adults. For practical purposes, if your child is under 18 or 19 and travelling to the United States, it is safest to assume that additional questions and documentation may be required before they are allowed to enter the country.

Travel Documents Minors from Canada Need To Enter The United States

Air Travel From Canada To The U.S.

For international air travel, including flights from Vancouver to U.S. destinations, every child must have their own travel document, usually a valid passport. This applies even to infants.

Canada and the United States both strongly encourage families to use passports for all international trips with children, regardless of the child’s age. Guidance from the Government of Canada and CBSA stresses the importance of carrying proper identification for all children travelling with you.

Depending on the child’s citizenship and the purpose of travel, additional documents such as a U.S. visa or ESTA authorization may be required. Airlines like Air Canada also set their own documentation and unaccompanied minor policies, which you should review well before departure.

Land Or Sea Crossings

For land or sea crossings, such as driving from Vancouver to Seattle, documentation rules can be more flexible for certain age groups. However, it is still safest to travel with:

• A valid passport for the child
• Supporting documents, like a birth certificate and a consent letter, if the child is not travelling with both parents

CBSA recommends that minors travelling abroad always carry their passport and that those travelling without both parents also have a consent letter signed by both parents and additional identification documents readily available.

Although some U.S. rules allow specific alternatives for certain children at land or sea crossings, those details can change, and exceptions do not limit the questions an officer may ask. In practice, a passport plus supporting documentation is the most straightforward option.

If your family uses NEXUS for frequent crossings, it may also be helpful to review how NEXUS membership interacts with children’s travel. Issues at the border or misunderstandings about consent can sometimes affect trusted traveller privileges, and a lawyer experienced with NEXUS passes and appeals may be able to assist.

Consent Letters For Children Travelling Outside Canada

Why A Consent Letter Matters

There is no single statute that always requires a consent letter, but both Canada and the United States expect to see proof that a child is travelling with the agreement of any official parent or guardian who is not with them.

The Government of Canada strongly recommends that a child carry a signed consent letter whenever they are travelling alone, travelling with only one parent or guardian, or travelling with relatives, friends, or a group, such as a sports team or school trip.

This letter is meant to show foreign border officials and CBSA that the child has permission from every parent or guardian who is not travelling with them. It can also help avoid delays, secondary inspection, or refusal of entry.

What Should Be Included In A Consent Letter?

Government guidance suggests that a well-prepared consent letter should generally include:

• The child’s full name, date of birth, and passport details
• Full names and contact information for all parents or guardians
• Details of the trip (dates, destinations, and accommodation, if known)
• The name and contact information of the accompanying adult, if any
• Any relevant custody information or references to court orders

Canada provides a recommended form and sample wording for a consent letter for children travelling abroad, and many families work with a notary public to witness the signatures. While notarization is not legally required, it is strongly recommended and can make border officers more comfortable accepting the letter as authentic.

Situations Where Extra Documentation Is Especially Important

You should pay particular attention to the documentation you prepare for your child or minors if:

• Parents are separated or divorced, and only one parent is travelling with the child
• One parent lives outside Canada
• One parent is deceased
• A child is travelling with grandparents, coaches, or teachers
• A minor is travelling entirely alone, including connecting flights through the United States

In these situations, border officials may ask to see a consent letter signed by the non-travelling parent or guardian. They might also request a long-form birth certificate that shows the relationship between the child and the parents listed in the consent letter. In cases where guardians are separated, divorced, or one is deceased, they may ask for certified copies of custody orders, separation agreements, or a death certificate.

Where consent letters are not realistically possible, or where there are disputes about custody or travel, it may be wise to obtain legal advice before making firm travel plans. Our U.S. immigration lawyers in Vancouver regularly help families crossing the border prepare ahead of time.

Airline Policies And Unaccompanied Minors

Airlines can set their own rules for unaccompanied minors, including:

• Minimum ages for travelling alone
• Required escort services and additional fees
• Documentation required at check-in and at the gate

For example, many carriers require that younger children travel as official unaccompanied minors on direct flights only, and they may require extra documentation beyond border requirements.

Always check your airline’s policy well in advance, as failing to follow carrier rules can lead to denied boarding even if your documentation would satisfy border officers.

How A Vancouver U.S. Immigration Lawyer Can Help With Minors Travelling Across the Border

Most cross-border trips for children go smoothly, but sometimes complications can arise, including:

• A child being delayed or refused at the border because of missing documents or inconsistent answers
• Questions about custody orders, parental rights, or relocation issues
• Confusion around required visas, ESTAs, or other U.S. immigration processes

In some cases, these issues overlap with broader immigration questions, such as a parent’s inadmissibility or an ongoing U.S. immigration application.

Our Vancouver U.S. immigration lawyers are familiar with the intersection between U.S. immigration rules, Canadian guidance for travelling children, and practical realities at border posts between British Columbia and Washington State.

While we cannot guarantee any particular outcome, we can help you understand the documentation likely to be expected for your child’s trip, review your consent letters and supporting documents for clarity, and consider the immigration implications for repeat or long-term travel.
