In order to be a perfect american, you need to change your name.
In my case, I changed both my given name and my surname, as soon as I got my citizenship.
Also, it is better to forget your mother language. That will make your English enhanced real quick.
Once you get used to it, you will find sth different and soon, you will realize that you are becoming the one of white people.
Trust me, because, by doing that, I got numerous benefits such as, white friends, big promotion in company and acceptance from the previlaged.
