I do not really think birthplace or where your ancestors comes from really bothers who is or not an real American. However, what really matters is what you can contribute to America. Nobody can see it, but everyone in this country can feel it. And they will surely be proud of you. So obviously, what you devoted to the society is the key feature whether you are American or not.
American Dream can best represent this. Though we were born in a variety of different places, though we came from different families, we are all Americans, 100% Americans because we hold the same American Dream. I am really proud of being one of the citizens of the United States of America and one reason for that is I indeed love this country deep inside from my heart. And what America told me was all about challenging myself and achieving my life goal. That means if you once had a dream, whether it was ambitious or not, you should stick to it, focus on it, and fight for it for your whole life, to contribute to the society, to push the human race forward. No matter where you come from, no matter you are rich or not, and in spite of your appearance, however, everyone can become an extraordinary person and achieve their goals eventually with their constant efforts. The best examples for this, are the forerunner of motor car industry—Henry Ford, who actually invented cars that affordable for everyone. And the co-founder of Microsoft Corporation——Bill William Gates, who pushed the human race forward by developing and exploring new techniques that made our life much more convenient. Indeed, they came from common families, but the remarkable things they did made them well-known for every single person in this world. I think I am also going to follow my heart and at least, try to do something really great for my country.
