Read the general life across the border overview
The principal's TN status settles her own work and nothing else. Her husband may accompany her in TD status but cannot work, including for his own Ontario company from a U.S. address. Her nineteen-year-old son may study in TD status but ages out at 21 and would then need his own status. Each of those facts has a date attached, and the household plan should be built from those dates rather than from the start of her contract. Hypothetical example: a Canadian horticulturist enters TN status while her spouse operates a mobile bicycle-repair business and their child is nearing the dependent age limit. The family must decide whether the spouse will perform work only outside the United States, obtain an independent category, or remain in Canada. It must also choose a school or status plan for the child before the birthday deadline. Those decisions are separate from the principal's job offer.
The spouse's activity, not his income, is what TD restricts
Hypothetical example: the nurse's husband runs a one-truck plumbing business in South Frontenac and proposes to keep serving his Ontario customers by driving back on weekdays while living with her in New York. Work performed in Ontario is Ontario work and TD does not restrict it, so a genuine commuting arrangement is lawful, though tiring. Quoting jobs, doing the books and taking customer calls from the house in New York is work performed in the United States, which TD does not authorize even though the customers and the payments are Canadian. The line is physical location, and a couple should decide in advance which side of it his business will operate on. Keep a simple location log if the spouse will continue Canadian work. The decision turns on where the activity occurs, so invoices and clients do not cure work performed from the U.S. residence.
The son's clock runs regardless of the plan
A nineteen-year-old can accompany his mother in TD status and enrol in a U.S. college without a separate student status, but he ceases to be a dependant on his twenty-first birthday. If he will still be studying then, the change to his own status, usually F-1, must be arranged before that date, with the school's certificate of eligibility and the financial evidence that category requires. If he intends to work after graduating, TD and F-1 answer that question differently again. Write his birth date on the family calendar as a hard deadline, because no employer letter or school acceptance moves it. Start the child's independent-status planning early enough to obtain school documents and make a genuine choice. A dependent classification does not extend past the age rule because a course is unfinished.
Sequence the household around the slowest person
The nurse's own timetable is governed by the New York licence and the TN admission. The husband's is governed by whether he closes, sells or manages his business remotely, which may take longer than either. The son's is governed by admission deadlines and his twenty-first birthday. The household should not adopt a single departure date until each of those has a realistic answer, and the nurse should not give notice in Kingston on the assumption that everyone travels together. Keep proof of the marriage and the son's birth certificate with each person's passport, since TD admission requires the relationship to be shown at the border every time. Revisit the calendar when the principal's start date changes. The family should move only when each person's status, work plan, and supporting relationship documents are ready for inspection.
