TD does not authorize employment, and the principal’s credential does not become the spouse’s qualification.
Assess the spouse’s own activity
Identify any independent lawful work route using the spouse’s actual facts. A shared move budget or similar education does not extend the principal’s permission.
Build an activity plan for each relative. TD classification permits a spouse and qualifying children to study, but it does not authorize them to work, freelance, invoice through a Canadian company, or provide unpaid labour that is really employment. The principal must be a Canadian or Mexican citizen with prearranged work in a listed USMCA profession and the profession's required qualifications; Canadian permanent residence is not citizenship. Decide before travel whether the spouse will remain in TD or pursue an independent classification. The mistake is assuming the principal's degree evaluation, employer letter, or TN approval transfers professional eligibility. A Canadian principal may seek TN at entry or through an employer's Form I-129, but neither method changes TD work limits or permits principal self-employment.
Hypothetical example: an Orford architect accepts a qualifying design position while her spouse, a landscape photographer, hopes to edit images for U.S. customers after the move. Her evaluation and architecture records support only her own TN file. The couple should identify whether his proposed services constitute U.S. work and, if so, secure his own lawful route before he begins. His Canadian permanent-resident card would not make him TN-eligible; citizenship, an independently listed profession, matching credentials, and prearranged employment would all require separate proof.
