The first problems with visas is being Dominican, no body wants Dominicans unless they have USA, Canada or Schengen Visa, where some countries allow us to visit without applying for a visa like Panama, Costa Rica, Mexico, Aruba, Curazado, Saint Marteen.
I was planning visit Brasil for my vacations, and when I was at the consulate the guy that check the papers was reading my job letter and told me, the minimum wage for the job letter must be 35,000.00 wtf, I said ok. thanks, go back and them made plans to go Cuba where we are welcome and had amazing 7 vactions days in Habana and Santa Maria in Cuba.
Consuls from USA embassy also are most of the times Idiots, My partner is Canadian I have 6 years canadian visa and travel aprox 2 or 3 times a year to Canada and I was Rejected for USA Visa because I dont have strong ties in Dominican Republic, the girl only opened my passport to see my picture in the passport, so its looks like all of them came from the same School when they have a Dominican in front. I also have 10 years mexican visa, visited for vacations Cancun in 2011 and mexico city in 2012 and never tryed cross the border in the south or north side.
So the best thing being Dominican is plan with time vacations or any travel you want to make and be ready to heard Denied, Rejected and have you Plan B always.
