My Dominican Republic citizen friend age 25 was the girlfriend of a 61-year-old US citizen from Houston. Her boyfriend was a naturalized US citizen originally from Mexico. Girl became pregnant. US citizen said he was going to Houston to get the naturalization papers. Girlfriend found out he was married. I think he received a divorce but I'm not certain. Citizen had a massive heart attack and died at 61 last October. Dominican girlfriend has a copy of his passport and driver's license. Deceased citizens name is on the 2-year-old's birth certificate and the 2-year-old has the last name of the deceased citizen. Deceased citizens family unreceptive in trying to help the 2-year-old. Question is how should the Dominican mother proceed with immigration and survivor benefits
