10 year ban over - now what

Hi

I have gone over many posts but can't find the simple answer to this question:
My 10 year ban for over staying in the US has ended, what do I do to allow me access to the US?

I did not dispute it nor did I even know I was banned till 6 years had passed. I do not want to live in the US or work there as I am very settled in vancouver. But I do want travel and many flights stop over in the US in LA so I need to be allowed entry. I have kept paperwork to show my emplyment, living expenses and involvement in BC plus have a written emplyment contract at present.

Thanks Vicki
