Read the general life across the border overview
Hypothetical example: Joachim holds TN status as a horticulturist and lives with his wife Saskia and two children, a household connected to Bradford West Gwillimbury. His employer is restructuring and his position may move to an L-1 transfer instead. The family assumes the change is his paperwork alone. Each dependant holds a status in their own right — TD in the present arrangement, L-2 in the proposed one — and a change of the principal's category requires each of them to be dealt with as well. Hypothetical example: A paper-conservation specialist changes from TN to L-1A while a spouse has accepted a U.S. job. The decision is to file each dependant's change on time and confirm the spouse's evidence of work authorization.
Derivative status is separate paperwork, not an attribute of the principal
It is natural to think of a family as travelling on one person's status, and administratively that is not how it works. Saskia and each child hold their own classification, tied to Joachim's but evidenced separately in their own records. When the principal moves from one category to another, the dependants do not migrate automatically; their status has to be addressed at the same time, and a gap for a dependant is a real problem even where the principal's own position is continuous. The practical rule is to treat the household as four cases with one common dependency, and to ask specifically what happens to each person on the day the principal's category changes. Make a person-by-person checklist of passports, I-94 records, and requested classifications so no dependant is omitted from the transition.
What each dependant may do changes with the category
The change is not merely procedural, because the rights attached to the two statuses differ. A TD spouse has no independent work authorization at all, whereas a qualifying L-2 spouse is employment-authorized incident to status under current USCIS policy. For Saskia that is a meaningful difference and one worth understanding before the family relies on it either way. Children may study in either status and are never employment-authorized. Anyone in the household who wants to work and does not fall within an employment-authorized derivative category needs a route of their own, decided by their own citizenship and qualifications rather than by the principal's. The household must decide whether a spouse can rely on derivative work permission or needs an independent employment category before accepting work.
Age, citizenship and the questions to ask now
Two facts should be established for every household before any change is made. The first is each person's citizenship, since Canadian permanent residence held by a citizen of another country does not open TN and can change which routes exist for a spouse. The second is each child's date of birth, because dependent status ends at twenty-one and the resulting deadline does not move for family convenience. A child approaching that age needs a separate plan, potentially a student route, arranged well ahead. Where the principal's category is changing, ask a licensed adviser to confirm the sequence for each family member rather than assuming they follow along. Age and citizenship should be recorded early because a child nearing twenty-one or a non-Canadian spouse may require a separate route.
