Neglito -
You may want to take a different approach with your studies. I guess I was thinking of more of a liberal arts type of degree with history, economics, sociology etc. type classes. However this is not considered a profession here.
There are numerous programs in the US that have connections to universities like PUCMM, UTEASA, and UNIBE, where you study at your home university for at least 1-2 years, then you can study abroad in the DR for a summer, semester, year.
These programs vary from very much group oriented - group trips, volunteer work, and assistance from a US based study abroad counselor, to not group oriented at all- you are pretty much on your own, with minimal assistance.
If you would consider this, the best path to take would be check out the schools, and while you are there talk to the international student departments. At PUCMM it is located in the same building as the cafeteria on the 2nd floor.
Also when looking at schools in the US check into their study abroad options, some schools charge the same tuition as their school, some charge the program fee, also check with the schools acceptence of foreign credit policies.
When I was studying at PUCMM, there were many dominican-americans who came down to study for a semester or year in the more organized program, it gave them a chance to learn a lot about their country in a condensed time. Many of them are now working as college professors,in social agencies in NYC or Lawrence, Lawyers or working towards their doctorate.
