No. TD does not authorize employment, including remote services performed in the United States for a foreign employer. The principal’s promotion does not create a dependent work benefit.
Keep the household’s income assumptions separate
A qualifying spouse and unmarried child under 21 may seek TD, but each intended activity needs assessment. If the family plan depends on the spouse working, identify a lawful basis independently rather than relying on the principal’s revised compensation package.
Households sometimes assume that dependent restrictions soften with time, that a spouse who has lived in a community for three years acquires some entitlement to work there, or that a long-settled teenager can take a part-time job like their classmates. If the letter names an initial period with possible extension, treat leases, school enrolment, and a spouse's resignation as decisions tied to that period rather than to a hoped-for renewal. Steps differ by nationality, since Mexican citizens generally require a visa and Canadian citizens generally do not, so confirm what each dependent needs instead of assuming the principal's route applies to everyone. A principal TN applicant must be a Canadian or Mexican citizen with prearranged work in a listed USMCA profession and the profession-specific qualification; Canadian permanent residence is a different status and does not create TN eligibility.
