Can a US Citizen have dual citizenship from the Dominican Republic IF that person has a mother as a Dominican citizen and was born in the US without using their US Citizenship?

Yes, a U.S. citizen can hold Dual Citizenship with the Dominican Republic if their mother is a Dominican citizen. The Dominican Republic allows individuals to acquire citizenship through their parents, known as "jus sanguinis" (right of blood). Therefore, being born in the U.S. does not prevent them from obtaining Dominican citizenship through their mother, even if they do not use their U.S. citizenship for this process.
