No. TD status still does not authorize employment, and a spouse's own work plan, including any role connected to the same company or referral, needs independent review.
Review family involvement in the same business separately
If a spouse or family member is also being considered for a role at the same or a related company, treat that as its own case with its own facts, rather than assuming the principal applicant's TN approval extends any work permission to them.
Employment is judged by where the person is physically performing the work, not by where the employer is registered, so a TD spouse logging in from a U.S. apartment is working in the United States without authorization. Spouses and unmarried children under 21 may be admitted in TD status; TD holders may study in the United States, and they may not accept employment, which regularly surprises households where both adults work. Confirm each family member's citizenship and civil documents early, since nationality determines which steps apply and marriage or birth certificates may need translation. TD permits study but does not authorize employment, and that includes remote or freelance work performed while in the United States, whether the client and payment sit in Canada or elsewhere.
