Who is it for: TD visas are issued to spouses and children under 21 years old of TN visa holders. TN visa holders are Mexican and Canadian professionals who work in the United States as part of the North American Free Trade Agreement (NAFTA). These professionals can include lawyers, pharmacists, engineers and other related types of work.
A complete list of professions covered under NAFTA can be found here.
Rules governing admittance to the United States under a TN visa are different for Mexican workers than for Canadian workers. Those same admission rules for each also apply to spouses and children seeking TD visas.

For Mexican citizens, they must apply for a TD visa in Mexico at a U.S. embassy or consulate. They will be required to show proof of their relationship to the primary TN visa holder and that the TN visa holder is meeting all the requirements to stay in good standing under this classification. TD visa holders can enter the United States at U. S. ports of entry or at certain pre-flight or pre-clearance inspection stations.
Canadian citizens do not need to apply for a TD visa, but they must meet requirements to be classified in the TD visa category. To do so, they must prove that they are Canadian citizens and that they have a verifiable relationship with the primary TN visa holder. A birth certificate or marriage certificate is acceptable in this instance. In lieu of a TD visa, a Canadian citizen must show copies of a TN visa holder’s admission documents, along with proof that the TN visa classification holder is continuing to meet all the requirements to stay in good standing under this classification. Canadian TD visa classification holders can enter the United States at U. S. ports of entry or at certain pre-flight or pre-clearance inspection stations.
