Read the general life across the border overview
Hypothetical example: a Guelph/Eramosa agronomist's household is about to make three separate mistakes at once. He plans to resign before his TN is decided; his wife, a registered nurse, expects to start hospital shifts on TD status; their nineteen-year-old assumes his TD status will carry him through a US college degree. Each error belongs to a different person and has a different fix, and none of the fixes is difficult if done before the move rather than after.
The spouse's error: expecting to work on dependant status
A TD spouse may study but cannot work; that is the rule for every TD dependant regardless of profession. A nurse who takes shifts on TD is employed without authorization. Her fix is her own route: Registered Nurse is a listed USMCA profession whose Appendix 2 qualification is a state or provincial licence or a Licenciatura degree, so with Canadian citizenship, a US employer's TN letter and satisfaction of any separate state licensing requirements she can apply for her own TN. The licensing step is the slow part and should start in Guelph/Eramosa months before the move. If the household could instead qualify through an L-1 or E-2 route for the principal, the spouse would be employment-authorized incident to status, which is a reason to compare routes with the spouse's work in mind rather than the principal's convenience.
The student's error: assuming dependant status lasts
An unmarried child under twenty-one may hold TD status and attend school, but he loses that status at twenty-one or on marriage. A nineteen-year-old starting a four-year program will need his own student status by his third year at the latest, obtained through a school certified by the Student and Exchange Visitor Program and with evidence of funds and intent to depart. Plan that transition now: choose a certified school, understand the timing of a change of status or a consular application, and avoid gaps. Also note that a TD student cannot work, including campus jobs, until he holds a status that permits it. His citizenship should be checked from his own passport rather than assumed from his parents'.
The principal's error: resigning before the decision
The agronomist's own mistake is sequencing. TN for a Canadian citizen is decided at a port of entry or by petition, and a defective letter can produce a refusal on the day. Resigning first means a refusal leaves the household without income on either side of the border. He should obtain a correct letter, apply, be admitted, and only then give notice and move. The family should move only after his admission and after the wife's and son's plans have documents behind them. A household ledger with one line per person, showing citizenship, intended activity, the route that permits it and the date it will be secured, exposes all three errors on one page and makes the order of operations obvious.
