Read the general life across the border overview
Hypothetical example: a Lantzville household moves to the United States on a work assignment with two children, aged twenty and fourteen. Both may attend school. Neither may work. One of them will cease to be a dependant within the year, and no filing by the parents changes that. Families plan carefully for the principal's status and then discover that the dependent side has its own timetable, its own limits and its own failure mode, which is that everyone's status is attached to a job that could end. Hypothetical example: A Canadian animation-studio employee must decide whether her twenty-year-old son needs a student route before the family accepts a two-year transfer.
Study is permitted; employment is not
Dependants of temporary workers may enrol in school, and this includes college and university, so a twenty-year-old can study while in dependent status. What dependent status for children does not permit, in any of these classifications, is employment. A part-time job, paid coaching, freelance design work billed to a U.S. client — none of it is authorized, and the fact that the work is casual does not change the analysis. Where a student wants both to study and to work, the alternative usually discussed is a student classification with its own rules on employment, which is a separate application with separate requirements rather than an upgrade. The family should choose a separate lawful route before the child reaches twenty-one, rather than after dependent eligibility ends.
The twenty-first birthday is a hard edge
Dependent eligibility for children ends at twenty-one. For the older child in this household that date arrives during the assignment, and the consequence is practical: the young adult needs a basis of their own to remain, most commonly a student classification, and that has to be arranged in advance rather than on the day. Schools need lead time to issue the documents a student application requires, and there may be a change-of-status filing to prepare. A family with a child of nineteen or older should put this on the calendar at the first consultation, because options narrow steeply once the birthday is close. School attendance does not authorize a child to earn income, including paid freelance work or a campus position.
Dependent status ends when the principal's does
The uncomfortable structural fact is that dependants hold their status because of someone else's. If the principal's employment ends, the family's status is affected as well, and any limited period allowed after a job ends is a matter of specific rules rather than a general grace period. This is worth discussing before the move, not after a layoff. Practical preparation includes keeping every family member's documents current and together, understanding what a spouse's own work authorization depends on, and knowing which adviser to call in the first week rather than the fourth. Each family member's own activity determines their route, and that is as true in a crisis as in a plan. A job loss by the principal should trigger an immediate review of every family member's independent options.
