I have a particular situation. I entered the US with a 3 month-stay visa in 2004 and stayed there until 2013. I don't remember the exact date I entered the US; I was probably 14 years old, since I started high school there. I renewed my French passport in the US in 2013 in order to return to France, because I was tired of being an immigrant with no papers/visa. I also wanted to see my close relatives after being apart 9 years away. Now that I am back in France, all I think about is returning to the US because life in France isn't what I expected. I got used to the American way of life and I miss it a lot. I didn't graduate from high school; I left and went off to work in a fast food restaurant.

They didn't even stamp my passport when I came back to France, so my passport is as clean as water, nothing on it. Don't know if that helps or not so just wanted to point that out.

What can I do to go back to the US? A friend of mine told me to buy a ticket to the US to see if I can enter the US again? What are some steps for me to check if I can enter the US? I paid to check with ESTA to see if I can, I put the information of my passport and everything but I answered "No" to all the questions such as "have you ever stayed in the US" and apparently my passport's good to go since I got authorization to enter the US from ESTA.

Any help would be greatly appreciated.

P.S : I was not arrested nor did anything out of the ordinary  

P.S 2 : I left the US willingly by myself.
