I just moved to BGI at the beginning of July, from Toronto. So far so good. weather is very hot
If you have Bajan citizenship, coming to Barbados will be much easier than it is for a foreigner. Most of us have to jump through hoops to work here. There is a lot of good information specific to this on britishexpats (dot com - i'm not allowed to post a web address yet) in the Barbados section. Lots of us on that forum who are not British, btw.
If you have lived in Barbados before then you will know what to expect. Many people think visiting a place is a good indication of what it's like to live there, but of course this is not always the case.
Living here is enjoyable for the most part for us. There are always tradeoffs, and it is nearly impossible to refrain from making comparisons to one's home country, especially if the item in comparison "works better" in the home country. That's all part of
culture shock. After a while, we may not notice these things anymore.
HTH. Foxy.
p.s. good luck!
