I want to move to cuba or Puerto Rico to study music , body building, boxing and literature?

Unless you're of Cuban decent or have Cuban relatives living in Cuba, you're not likely to buy a home or be able to get a job in Cuba. Even if you did you're not going to earn a lot of money in Cuba. Cubans earn on average $25-$30 a month. Also jobs there go to Cubans before any one else. I think it  would be easier for you to move to Puerto Rico. If you've never been to either one then, I would suggest spending a few weeks in either country to see how you like it there. You may also have to have a grasp of or be fluent in Spanish, to go to school in Cuba or Puerto Rico. Cuba is a communist country, Puerto Rico is a territory of the US. You can always google search that information. 

It's just TOO Cuban......;}

I would recommend the School of Divinity just off pier 14 along the dock road in San Juan.  The College of Black Angus used to be the best place, but that has closed down.

So book your flight and go there
