thank you @beloved_dingo for your response!
No, she has no family living in the US. ALL of her family reside in the DR. The American pastor here works very closely with her sister and brother-in-law who are pastor a church in the DR. The American pastor and his family visit the DR several times per year. That is what I meant by family ties. She is an 18 year old high school student so she lives at home with her parents and siblings. There is no lease as she lives at home with parents. She does physically help her mother care for her younger siblings and go to school therefore she does not have a job. My son still lives at home, so she would be staying with us and visiting the American family and churches that help support the church in the DR. We were just hoping to give this young lady an opportunity to visit. Our intentions and motives are genuin and honest. 😞
