I have a lot of experience moving internationally with companies. Not Universal, but multinational companies.
They always use professional 3rd parties …. They deal with insurance & liabilities, customs/excise, booking cargo space on ships/planes etc.
Lot of that is specific to international moves, but not all of it, especially the insurance part.
My bet is also on this is not a coincidence per se, but filming content relating to their park plans.
In fact: if it were my guess, any homes they pick up on Manor Road will serve as some initial accommodation in the early stages, but more for short-term transient accommodation rather than longer-term international relocation of staff.
