I am interested in living overseas and becoming an expat. I don't have a great job right now, no family obligations and I'm single. I have always wanted to explore more of the world and think it would be awesome to live overseas. I have traveled extensively but only ever lived in another country for 6 months, 20 years ago. I lived in Japan.

Any recommendations for the cheapest and easiest country to legally move to? By easy I mean, getting visas or other permissions. I prefer a warm tropical place. I would also like to find some form of work while there. Volunteering is cool but I would need to make some money. I speak basic spanish.

Mexico is one consideration but I have heard that it is a hassle for Americans to live there.

any suggestions?
