How can my child from my ex-partner be included in my new husband’s Greece golden visa application?
Me and my fiancé are considering moving from the US to Greece. I have a daughter, but he is not the father. My fiancé wants to buy property (for over €250,000) for a golden visa. Would my daughter and I fall under the golden visa program and be added to his application if we do get married? I'm concerned about my daughter’s status and him not being on her birth certificate. How does that work?
