Before you go to a great deal of trouble there are not many other first world countries that you will be allowed travel with a Dominican passport.
The DR has found that once Domincan citizens set foot in first world countries they do not come back.
If you want to visit Indonesia and the like fine but you will not be going to the US, Canada, Germany, France etc. unless you marry one of their citizens.
No slight intended against Indonesia, I am sure it is a fine place.
Dominicans risk their lives in small boats to get out of here.
Well it depends on where you go on what the advantages there are for you personally. We went to Colombia and it cost my wife and I 85 dollars each using our Canadian passports. If we were traveling on a Dominican passport there would have been no cost, no visa...etc. This applys to several countries.
