You want to live in Jamaica ...

then you should prepare things by overthinking:

-your income in Jamaica
-your support in Jamaica
-your legal position after migration into Jamaica and other rights
-you should know a bit about Voodoo and how it works ..
and certain things else

Jamaica is nice but also a bad place. Do not dream like a child.
But prepare things normal: probably you can find here some information which help you further ( and an e-book for free )
