The child’s age transition needs its own plan even if the parents and younger siblings remain eligible for their statuses. Discuss housing and travel arrangements without assuming the whole family must follow one renewal date or one classification. Sequence the household’s decisions behind the one that is genuinely upstream. The parent’s employment period governs the spouse’s TD and the younger siblings’ TD alike, so a change at the employer reaches every dependent at once. The child approaching 21 is the only member whose eligibility ends for a reason the employer cannot affect.
Make living arrangements conditional on a lawful route
If the child intends to remain for studies while the family’s plans change, confirm the lawful basis for that stay independently. School housing availability does not settle immigration permission. Agree on a practical fallback if the intended study timeline cannot be met.
Decide what each household member would do if the parent’s position ended early, and write it down before it is needed. A spouse holding TD may study but is not authorized to work by that status, so a household budget assuming a second income has to be tested against the permission actually held. Where the plan depends on one member remaining after the others leave, identify now which document would support that stay, and what has to be requested while the current period is still running.
