Well, you could start by introducing yourself a little. You could say where you were born and where your parents were born.
Next you could say how American traditions have affected your life. For Example, you could talk about 4th of July celebrations and how they have deepened your love for the country.
Then, you could compare the laws you agree with and disagree with and why.
My advice is to just write about your traditions that are associated with america and how they have shaped your life.
Hope this helps! :)
