Read the general life across the border overview
A Delson family may have prepared its temporary U.S. move while a child was younger. Revisit age, marital status and the actual category before assuming the old plan remains valid throughout an extended timetable. Make a separate eligibility timeline for every family member rather than treating the principal’s approval as a household decision. A first review records each person’s date of birth, marital status, passport, planned entry date and intended activity, then identifies the first date on which a dependent category may no longer fit. Hypothetical example: A classical instrument restorer accepts a U.S. assignment while a 20-year-old child plans to marry before the family’s expected entry. The concrete decision is whether the timing still permits dependent status or whether the child needs assessment of a separate route. The birth record, passport, marriage plans and category-specific rules settle that issue; a school enrolment letter does not. Address this before booking travel or accepting employment, because a later change may leave fewer practical choices.
Use the temporary category’s criteria
The dependent-child categories discussed here generally require an unmarried child under 21. Do not import an immigrant category’s age-protection rule into TN, E or L dependent status without a legal basis. A school acceptance does not establish immigration eligibility. Keep copies of records showing both age and marital status, and update the timeline when travel moves. An old household checklist may no longer describe the person’s current facts.
Consider the person’s actual next step
If eligibility or authorized stay may change, obtain an assessment of the available process for that person. An independent route has its own conditions and should not be described as already approved because the rest of the household qualifies. Ask what the child plans to do in the United States before choosing a route. Study, work and a future independent filing raise different questions.
Keep work permission separate
Dependent children do not receive the qualifying E/L spouse employment benefit; TD does not authorize employment. Review the child’s own status and any proposed activity. A birthday, graduation or family business opportunity is not itself permission to work. Do not schedule a job around assumed dependent permission. Confirm the person’s status and the applicable work authorization before any services begin.
