TD does not authorize employment, including remote services performed from the United States for a foreign employer. A short stay does not create an exception.
Assess the spouse’s activity where it occurs
A qualifying spouse or unmarried child under 21 may seek TD, but the principal’s permission does not give dependents a work benefit. Do not rely on the Canadian payroll address alone when planning work during the visit.
Gather marriage and birth records, passports, and prior immigration documents, and avoid making the principal's employment letter carry facts that belong in a dependent's record. TD status permits study but never authorizes employment, so translating brochures, answering customer messages, or invoicing through a Canadian account can still amount to work rather than harmless family help. If the added income or schedule change affects household planning, such as childcare or a spouse's own work arrangements, discuss that separately from the immigration authorization questions, since the two issues have different evidence and different decision points. If the extension crosses a school term or a planned return, decide early, and remember that TD permits study but does not authorize work, with proposed remote or unpaid activities requiring specific review.
