Accompanying TD status does not authorize employment, including a job mentioned in the principal’s employer material.
Separate the spouse’s offer from the principal’s case
If the spouse receives a genuine offer, examine the spouse’s own eligibility and authorization before work begins. A department’s hiring needs do not extend the principal’s TN permission to family members.
Treat the spouse’s proposed job as a separate immigration matter before accepting duties, training, or pay. TD classification is derivative of the principal TN and permits study, but it does not authorize employment. A vacant position in the same attachment does not change that restriction. Collect the spouse’s citizenship evidence, independent offer, actual duties, credentials, and ownership information, then assess whether another work-authorized classification may fit. If TN is considered, Canadian or Mexican citizenship is required; Canadian permanent residence is not enough. The offer must concern a listed USMCA profession, meet that profession’s qualification rule, and be prearranged rather than US self-employment. The avoidable mistake is allowing informal help to begin while paperwork is being explored.
Hypothetical example: A Saint-Ambroise dietitian obtains TN employment, while her spouse is offered a quality-control position appearing elsewhere in the employer’s departmental appendix. He cannot perform that job in TD status. The family separates his offer from her approved activity, verifies his citizenship and science credentials, and waits for his own work authorization before he joins any shift. Her TN documentation neither transfers to him nor converts the unused opening into authorized spousal employment.
