Read the general life across the border overview
Hypothetical example: a County of Brant household where the principal takes an L-1B assignment in the United States, his wife wants to keep her Ontario teaching position and commute, and their children are fifteen and twenty. Three separate questions follow, and answering them together is what usually goes wrong: whether a dependant must live in the United States, what the spouse may do while she is there, and what happens to the older child in the months before a twenty-first birthday. Family planning works when every person receives a separate legal and practical review. List the principal's classification, each dependant's relationship and age, the partner's intended work or study, intended travel pattern and any school or licensing deadline. Hypothetical example: a transfer principal's nineteen-year-old child wants to manage an online retail shop from the U.S. while attending college. The decision is whether the child has independent permission for that activity before it begins; a parent's status and tuition payment do not answer it.
Dependant status is permission, not an obligation to relocate
L-2 status admits a spouse and unmarried children under twenty-one for the same period as the principal. Nothing in it requires them to move, and a spouse who spends most of the year in Ontario keeping an Ontario job is not misusing the status by being admitted in it when she visits. What she should watch is the practical side: long absences make it harder to show a U.S. residence if that later matters, and each admission is a separate decision by an officer. The cleaner framing is that the principal's assignment sets the household's legal shape, and each member decides independently how much of the year to spend under it. Carry relationship records and current principal-status evidence for each dependant travel event. A person who spends much of the year in Canada may still need to explain the purpose and temporary nature of a U.S. admission. Do not use an immigration classification as a substitute for deciding where the family will maintain housing, school enrolment, tax residence and health coverage.
What the spouse may do on either side of the line
An L-2 spouse is employment-authorized incident to status, so if she takes U.S. work she may do so without waiting for a separate document. Teaching in Ontario is outside U.S. immigration law entirely and needs no permission from it, though a cross-border tax adviser should look at residency and withholding before the first pay period. Two traps are worth naming. Her Ontario teaching certificate does not authorize teaching in a U.S. state, which is a licensing matter with its own timetable. And if the assignment later converts to a category whose dependants cannot work, such as TD, her ability to take U.S. work disappears with it. For a working spouse, separate immigration authorization from occupation-specific rules. The admission record may establish permission to accept U.S. employment in the appropriate dependant category, while a state board, school system or employer decides qualifications to practise. Build the professional credential timeline before accepting a licensed job offer.
The twenty-year-old is the urgent file
Derivative status ends at twenty-one and on marriage, and for a child already twenty that deadline is closer than any petition timeline. Enrolling in a U.S. college does not extend it: college attendance is permitted for a dependant but does not change the age limit. The workable step is to plan a change to a student classification, with its own admission and financial requirements, well before the birthday rather than in the month of it, and to check the intended school's certification for that purpose first. The fifteen-year-old has years of runway, but the same conversation should happen once rather than twice. While in L-2 child status, each child may study but may not work. For an older child, record the exact age deadline and work backward to any independent student or employment option. Marriage can also end derivative eligibility. The family must decide whether to pursue the independent status early, remain outside the United States or revise the education plan; waiting for the birthday month leaves little room to correct missing school or financial documents.
