Here is the new provision in the Constitution.
Article 18. Nationality. The following persons are Dominicans:
1) The sons and daughters of a Dominican mother or father;
2) Any person having Dominican nationality before the entry into force of this Constitution;
3) Any person born in the Dominican Republic, except the sons and daughters of members of foreign diplomatic and consular missions, and of foreigners that are in transit or who reside illegally in Dominican territory. A person in transit is any foreign person defined as such by the laws of the Dominican Republic;
4) Any person born in a foreign country, to a Dominican father or mother, despite having acquired, by place of birth, a nationality different from that of their parents. After reaching the age of eighteen, such persons may choose to acquire dual nationality or to relinquish one nationality, before the competent authority;
5) Any person who marries a Dominican man or woman, provided that such person chooses to acquire the nationality of his or her spouse and fulfills the requirements established by law;
6) The direct descendants of Dominicans residing in a foreign country;
7) Any person naturalized in the Dominican Republic, pursuant to the conditions and formalities required by law.
By the way, I'm in the process of translating the Dominican Constitution into English. It should be ready for publication by January or February at the latest. This is a first uncorrected draft of article 18.
I'll be needing two or three beta-readers, preferably lawyers. Those interested please let me know.
