The process is long and tedious.
You need all of your professional documents, transcripts and certifications to be translated by a legal translator into Spanish. (Edited to say: "Yes, I did forget something") These documents then must be certified by the nearest Dominican Consulate and then, once in the Dominican Republic, they must be submitted to the Foreign Office for re-certification. Then they go to CONES--I think (end of edit)
All these documents go then to the CONES-the National Council of Higher Education-for review.
You need to enter a Dominican University, to take some course work.
You need to obtain your "execuator" , the equivelent of a license.
Recently the Dominican Medical Association started to re-make itself into the Dominican College of Medicine--similar to the AMA..to practice you will have to belong to this organization.
I am sure that I have missed something, but you get the picture.
