Sorry, don't take wrong what I said
I went to already some (included some french Caribbeans island too) ; ok it's not unsafe as Brazil or Colombia but it's not my definition of 'safe' places either.
I like big cities, vibrant, with lot of options to going out, bars, restaurants and possibility to have everything almost 24/24.
The fact to be close to US I really dont care because I am not attracted at all by US country (ofc i already visited several times), but i dont care about NYC or Miami TBH.
For Bahamas I was sincerely very disappointed (even for holidays..).
Globally I think Caribbeans island can be "more ok" if you have connections there and/or you go there with your family, not as a single life (from my opinion and lifestyle).
If you read my first post, I would prefer to avoid Dubai if I have to spend 90days there. I just want to spend approximately my year, as explained in the 1st post (so never 5/6months anywhere) AND get a safe and efficient tax residency somewhere (else?) without minimum presence required, preference outside EU. Otherwise I just keep NHR scheme in Portugal if no better alternative in my example.
