Macorís is right.

A resident does not become a Dominican citizen automatically after a certain time as a resident. A foreign national who has lived in the Dominican Republic as a permanent resident for two years or in certain cases, six months, may apply for Dominican citizenship. The petition MAY be granted at the discretion of the President.

By the way, Macorís, are you from San Francisco de Macorís or San Pedro? Yo soy francomacorisano.
