Moving to Puerto Rico in the future?

Puerto Rico is Awesome! Most people are super friendly. The service in some places is not that good though. It's like summer all year round. I dont know what you mean with casual but people here dress a little less casual than Americans( ex. they dont wear pajamas to the grocery store). You will probably get paid less than you do in the US doing the same job. Real Estate is really expensive also. Other than that PR is a great place to live in. We are super cool people, we love to party. :)
