In regards to this topic, I constantly read where DR1's own in house legal consultants, Guzmán Ariza, are frequently quoted with the phrase "legal work around", as it relates to paying as you leave our country.
Here is another quote from the same legal entity, that rarely, if ever gets mentioned by those truly obsessed with the situation......
"A foreign national, such as a retiree, a person intent on doing business, or an investor, who seeks to stay in the Dominican Republic for
a year or more should consider obtaining residency status."
The rights of citizenship are only bestowed upon a Dominican national who has reached the age of eighteen, or who is married or has been married before..
