A family that is relocating to the UK on a Tier 1 (Investor) visa retains a cook and a nanny at their home on the outskirts of Moscow. The family would like to bring these along, but they are not mentioned as dependents on the T1 visa, and they are not related to the primary T1 holder.
The family contemplates eventually qualifying for British citizenship with a long-term view towards keeping two households and shuttling the domestics back and forth as needed.
Do the cook and nanny need to apply for a work permit on Tier 2 of the points-based regime? How would they qualify given that the EU has lots of people who could presumably fill those roles? Does the T1 primary need to clear the Resident Labour Market Test hurdle? Are there any other special considerations that need to be considered? Or can they simply chain together continuous visitor visas to remain in the UK?
