Each family member holds whatever status was actually granted to that person, with its own validity period and its own permitted activities; nothing is inherited from the principal’s travel pattern. A school enrolment, a resignation letter and a lease each convert a plan into an obligation, and every one of them depends on a status that is not settled until the specialized-knowledge account and the qualifying year abroad have both been assessed.
