Read the general life across the border overview
When a Quispamsis accountant takes a TN role, his wife, a high-school teacher, can accompany him in TD status and their son can attend college as a TD dependant. TD does not authorize employment, so her teaching would need its own category, and the son's derivative status ends when he turns 21. Each person's plan has to be written against the rule that applies to that person.
Separate presence from permission
Hypothetical example: a Quispamsis accountant with a CPA designation accepts a TN role at a U.S. firm. His wife has taught mathematics for twelve years and assumes she can apply to local schools once they arrive. TD status permits her to live in the United States and to study, but not to work. Teaching would require her own basis: a TN application if her qualifications and a school's offer fit a listed profession, or another employer-sponsored category. Her Canadian citizenship, her degree and the school's willingness to write a proper letter are her facts; his TN approval does not transfer any of them to her. The household should treat her employment as a second application with its own timeline.
Check the listed profession and the state's licence
The USMCA list includes college, seminary and university teachers, but not primary or secondary school teachers, so a high-school position would not fit TN however qualified she is. A community-college position could, if the role is genuinely at that level and she meets the baccalaureate requirement. Separately, U.S. public schools generally require state teaching certification, which is a licensing matter outside immigration. She should approach a prospective employer with both questions: whether the role is one that a listed profession covers and whether the state will recognize her certification. If neither works, remote work for a Canadian employer while physically in the United States is not authorized under TD either.
Plan the son's timeline around his twenty-first birthday
Their son is nineteen and starting a four-year degree. He may accompany his parents as a TD dependant and study, but TD status is available only to unmarried children under 21, so his derivative status will end before he graduates. At that point he needs his own status, typically as an F-1 student sponsored by the college, which involves its own application, evidence of funds and a change of status or a departure and re-entry. The family should ask the college's international-student office now about the process and timing, so that the transition is planned rather than discovered. His own future employment in the United States would then depend on his own qualifications and route, not on his father's TN.
