I lived in the US for about 11 years went to school over there until I graduated from high school then I moved back to my country of origin because school was too expensive for non citizens, is there anyway I could go back legally?

You can apply for a visa, but are not guaranteed depending on what you want the visa for and why you intend to stay in the US.

You're banned for 10 years from the date you returned to your home country.
