Based on the internet resources and what people have posted or suggested here, there are only three countries that Dominicans can visit without obtaining visa before arrival that Americans cannot.
Russia
Cuba
Iran
Does this seem correct?
thats incorrect, there more countries that we can visit without visas,
Nicaragua
Guatemala
Honduras
El Salvador
Belize
Cuba
Trinidad & Tobago
Colombia
Ecuador
Perú
Paraguay
Japan
Turkey - eVisa
Qatar
Hong Kong
and some others that I do not remember now.
Russia, Serbia and Brasil didnt finish the paperworks of the process of free visa entry for Dominicans, so hopefully we will be able to travel free visa at some point of the 2019.
If you have USA, Canada or Schengen multiple visa and its been used at least one time you can enter Visa free to Panamá, Coista Rica, Aruba, Curacao and San Martin.
If you have multiple USA Visa or UK Visa and its been used at least one time you can enter visa free to Paraguay
If you have multiple USA Visa or Schengen visa and its been used at least one time you can enter Argentina with e-Visa.
If you have multiple USA visa and its been used at least one time you can enter visa free to Mexico.
Everything is always changing so I recomend always verify with the consulate before book a flight.
