Immigration Issues/Possible double nationality
Hello. My name is Mario. I was born and live in Mexico. My mother is also mexican and my father was born in the States. He has the American nationality and lives in Mexico with an FM2. A lot of people have told me that I can get the double nationality simply because my father is american, but that I can only get it if I am younger than 21. I am 19 and in March I am turning 20. Is this possible? If so, where can I apply for it and what are the costs/requirements. Thanks in advance.
