Read the general life across the border overview
Financial dependence or a disability does not by itself establish eligibility under a category limited to unmarried children under 21. Record the child’s actual circumstances and ask what routes and procedures apply. Avoid treating the household’s care plan as an immigration classification.
Gather facts needed for an individual assessment
Hypothetical example: parents planning a transfer assume their 23-year-old child can accompany them as a dependent because the parents provide daily support. Record age, marital status, citizenship, existing immigration history and intended activities. Provide relevant information through an appropriate private channel rather than including unnecessary medical detail in general employer documents.
Keep ordinary age rules and specific protections distinct
TN dependents in TD include qualifying spouses and unmarried children under 21. E and L dependent children have their own eligibility requirements; spousal work authorization does not extend to them. In immigrant processing, any applicable child-age protection must be assessed under the actual category and dates. Do not assume disability or payment freezes age or creates an exception.
Coordinate the care plan after identifying immigration options
List treatment continuity, insurance, accessibility, travel assistance and who would provide support if the parents move first. Have immigration and relevant care professionals address their respective questions. A school place, insurance quote or care arrangement does not supply lawful status. Keep alternatives and unresolved decisions visible before making a move that depends on all family members entering together.
