Commissioning tends to run in intense phases with shift coverage and uncertain end dates, which sits badly with moving a household on the same day. Eligible spouses and unmarried children under 21 may seek L2, and a spouse in valid L2S status is employment authorised incident to that status.
Consider a staged move
Where the first months are dominated by ramp-up, families sometimes plan a later arrival for dependants, which changes what documents each person needs and when. Decide whether school enrolment or a spouse's employment should drive the date instead. If a spouse intends to work, ask for that route to be assessed on its own facts rather than treating employment authorisation as something the principal case delivers automatically.
Commissioning phases and household moves compete for the same weeks, so decide which one is allowed to move. Eligible spouses and unmarried children under twenty-one may seek dependent classification, with a spouse in valid dependent status employment authorised incident to that status and children not authorised to work. A staged arrival changes what each person needs and when, and it changes medical, insurance, and schooling arrangements at the same time.
Where a spouse intends to work, ask for that to be assessed on its own facts early, since assuming the principal case delivers it can leave a household without income for months. Put the dependants documents on the same checklist as the corporate evidence rather than on a separate one.
