My Postgraduate studies

I don´t know what I’m going to do when I finish the university but I have some options. The first one is to take a L.L.M in Civil or Commercial Law in Europe or U.S.A because here in Chile there are too many lawyers. There is too much competition and I need a specialization (and a second language) to have a good job. 
The second option is to study for a PhD because it's necessary to be a teacher in the University. That is an idea that I don't refuse, to be a teacher, maybe a History teacher.
I want to study in another country because I want to live in another country. I didn't know what type of course I wanted to take, but I found some information and now I think that I want to take a blended system course, because I want to have time to travel around the country where I study. That's why I will keep on studying english.

I want to study the history of the institutions, the different law systems in the world, like common law and continental law. I want to learn how contractual law works in different countries. But if I have to choose one specific area I would choose to study Mining Law because it´s a very important area for Chilean economy and I enjoyed that course very much.
