TD does not authorize employment, including remote work while physically in the United States.
Review the spouse’s activity independently
A project milestone does not change dependent permission. Children may study while maintaining applicable status, but do not gain work rights solely through TD.
The TD category exists to keep families together; it does not carry work authorization, and the question of whether an activity is employment is answered by what the person does, not by where the employer is incorporated or which bank pays the salary. A spouse and children's own plans depend entirely on which immigration category the applicant ultimately qualifies for, which is unresolved in this scenario until the citizenship question is settled. Decide what happens if the spouse's own route takes longer than the move itself: does the household relocate on the principal's timeline with the spouse's work plan still pending, or does the family wait? Set out each dependent's admission record and its expiry alongside the principal's, since those dates do not always align and are not extended automatically by a school enrolment or by the principal's own extension.
