TD does not authorize employment, including a support role that does not require the principal’s professional licence. The spouse needs a separate lawful basis permitting their actual work. TD dependants may study, but they may not work. The fact that the employer can hire the spouse under its own qualification rules does not establish immigration permission.
Review the spouse’s offer independently
Identify their duties, citizenship and credentials and assess any route of their own. Keep their intended start separate from the principal’s conditional offer. A household should not count on support-role income while the required work authorization remains unresolved.
Begin with each person's passport, relationship records, age, own career plans, and intended U.S. activity. The first review should produce a household plan that names the principal route and every separate work, study, or travel question.; each conclusion should point to the record that settles it. Next, settle the principal case, then review relatives one person at a time. This order keeps a later explanation from being asked to repair a missing fact. What commonly goes wrong is informal help in a family venture may become unauthorized work. Preserve dated source material and identify the unresolved issue instead of using a confident generalization. Hypothetical example: A museum curator's spouse plans to sell exhibition catalogues online after arrival. The review separates the curator's temporary assignment from the spouse's independent business-permission issue. The decision is whether the actual record supports the proposed activity now, requires a different sequence, or calls for a separate route. TN requires eligible Canadian or Mexican citizenship and a listed professional category. A Canadian may seek admission on arrival or through preclearance, while an employer may submit an I-129 to USCIS. It cannot be structured as self-employment through a U.S. enterprise the worker owns or controls.
