TD periods are tied to the principal's, but extending the principal does not automatically extend a dependant. Each family member's position has to be checked, and the steps depend on the individual's own nationality and where they are.
Check each dependant's own dates
Pull the admission record for each family member rather than assuming they match the principal's. A spouse and unmarried children under 21 may qualify for TD; a US-citizen child does not need it. 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.
If the instructor enters first to begin course development and the family follows before the term, prepare the dependents' documents on their own timeline and by each person's nationality, since the steps differ. A licence condition can move a start date by months, and dependants generally cannot proceed ahead of the principal. TD dependants may study, but TD status does not permit employment. List the repayment triggers, due dates, savings, principal applicant’s expected earnings, and any lawful alternatives before accepting the benefit. The principal’s professional authorization is not shared by the household.
