Question:

Is it possible to legally make my middle name my last name in America?

My middle name is Mitchell and I dont like my last name. Can I make my last name officially Mitchell and completely eradicate my last name from all official documents? When I apply for a job can I use my new name and not tell them I used to have this old name?
