Dominican Nationality Through Descent

Article 18, Section 6 of the Dominican constitution extends nationality to "the direct descendants of Dominicans residing abroad", so, how would I, the grandson of Dominicans (through my mother) go about claiming Dominican nationality? My mother and I were both born in NYC and both only hold U.S. nationality. My grandparents, however, are dual citizens of both the U.S. and the Dominican Republic.

That's the thing though. I don't she is required at all in the equation except needing her birth certificate to prove I am descended from a Dominican. There is a whole separate section about children of Dominicans, and if she had gotten Dominican nationality, I would get Dominican nationality from that other section of Article 18, extending Dominican nationality to children of Dominicans. That is why I was confused on their wording. I presume I would just need my birth certificate, hers, my grandfather's and possibly also his cedula.
