Just remember that if you have any record (don’t think you do, but never know) such as once upon a time doing jail time, you’re essentially disqualified from naturalization even before you start the application process. At a certain point you will be asked to submit a “buena conducta” from the police department in your current SC town and that is simply to see if you have a record of disobedience with the law. Some chronic diseases such as HIV/AIDS will also disqualify you (at a certain point you will have to do a medical exam). You will also have to know certain aspects of Dominican history, a good understanding of Spanish and other things.
The only way you will never be asked for any to receive Dominican citizenship is if at least one of your parents is Dominican which simply means you have Dominican nationality since birth and simply need to get Dominican citizenship. No medical exam, no testing on Dominican history, no Spanish language profeciency, no presenting a “buena conducta,” you don’t even have to pay everything foreigners are charged (and that’s before a lawyer if used) as part of the fee is subsidized by the Dominican government. You don’t even need to translate anything from another language to Spanish as the Dominican government will automatically do it for you (usually the birth certificate which in countries like the USA will obviously not be in Spanish.) With the case of Dominicans born abroad, you simply need an official copy of your birth certificate from the town hall of the town you were born in, a copy (front and back) of a Dominican cédula of one of your parents (even if expired), and the small fee. That’s it. In a few months (much shorter than to foreigners naturalizing) they will take the photo for your cédula and do one right there if at the NYC consulate. At the same time you can also get the Dominican passport.
There is a slight difference between the Dominican citizenship naturalized by a foreigner and Dominican citizenship to Dominicans born abroad. For example, one such difference is that even a naturalized Dominican citizen isn’t allow to be president of the DR, but a Dominican citizen of a Dominican born abroad has no such limitations. Dominican citizens born abroad get the same exact citizenship that Dominicans born in the DR have, no difference at all. Naturalized Dominican citizenships don’t quite get the citizenship as Dominicans do given the small differences.
The other benefit that would apply to foreigners (not necessarily Dominicans born abroad) is that if you have Spanish citizenship, the entire naturalization process is expedited so you get Dominican citizenship faster than say a foreigner with USA or Canadian citizenship. However, the Dominican citizenship that Spaniards get has the same limitations as of other foreigners that naturalize except Dominicans born abroad. For the Dominican government, Dominicans born abroad are basically Dominicans through and through, hence it’s so easy to get Dominican citizenship.
