Every dependant's permission is derived, so the ceiling that ends the principal's classification ends theirs on the same day. A partner working under authorisation that flows from dependent status stops on that date too. Animal health credentialing, meanwhile, runs on the relevant state board's own timetable and should be settled before relocation.
One terminal date for four people, and one licence clock
Households plan around school years and careers, and both outlast this classification. Because dependent permissions derive from the principal's, the whole family reaches the same terminal date together, which is worth naming out loud rather than discovering when an extension is refused. That has a particular sting for a partner who has built something locally: the ability to take a job here arrives with dependent status rather than being held independently, so it is only as durable as the classification underneath it.
Separately, an animal health credential earned in British Columbia is not portable by default. Regulation of veterinary technicians differs considerably between jurisdictions, with some assessing foreign preparation by examination, some requiring further coursework, and some regulating only the use of the title. Write to the relevant board before the move and obtain the answer on paper.
Younger household members may enrol in school, may not take paid employment of any kind, and lose dependent eligibility on their twenty-first birthday.
