Moving to Grand Cayman Island

[Steven]

I've strongly considered it, but I've had relatives who worked in the BVI which is legally a similar situation.

The main misunderstanding people have is what citizenship is, mainly because the law has been chopped and changed so much in the last few years. A citizen of a British Overseas Territory has the right to reside in the UK and is treated as a British citizen - but not the other way around. Moreover there is more to it than simply being a BOT citizen, you also have to be a "belonger" of whichever territory it is in question. The territory sets the rules as to how they determine who can become a belonger, generally if you meet that rule you then become a BOT citizen at the same time (although correct me if I'm wrong if you're already a British citizen you simply become a belonger). So you have to be both a belonger and a BOT citizen to have full rights in whichever territory it is.

The Cayman Islands, the BVI and Bermuda are the toughest. Generally it means marrying someone who is a belonger and remaining married for a very long time, on the Cayman Islands it's 20 years, iirc.
