I was adopted by my step father when I was 10 years old. Recently I found my birth father who is Greek and lives in Greece. I am interested in becoming a dual citizen both US and Greece. Since my adoption, my step father is now listed as my real father on my birth certificate. Will this prevent me from proving my biological father is a greek citizen? What is the first step in becoming a dual citizen? Is there any chance that I can?

You may have never lost your Greek citizenship. Check the records in the municipality where you were registered upon your birth...
