I already have a U.S. passport and a Philippine passport, both are still up to date and are not expired yet, i went here in U.S. using my philippines passport because i am just a green card holder, and then i applied for a U.S. passport. because i am under age, they granted me the U.S. passport because my father is a naturalized citizen, does having these two passports mean that i am considered a dual citizen already?
