Dependent applications rest on the principal's position, so an unresolved discrepancy in the principal's duties can delay the family's plans too. Spouses and unmarried children under 21 may qualify for TD, with nationality-specific steps, but only once the principal's case is in order.
Sequence the family behind a settled description
Avoid fixing a family start date, ending a lease, or enrolling children on the assumption that the description issue is minor. It may be, but confirming that costs a short review while reversing household commitments does not. Note also that TD permits study and does not authorize employment, so a spouse who plans to work should treat that as a separate question from the outset.
If a spouse also works in analytics, their qualification does not confer employment permission through TD. The spouse may have a separate professional history or offer, but it needs its own lawful route. Describe the spouse’s duties, citizenship and intended location of work. Treat every task the spouse might perform as work even if it is brief, unpaid, remote, or covered by the same confidentiality agreement. A spouse who intends to work needs an independent status that permits that activity.
Pull the admission record for each family member rather than assuming they match the principal's.
