During my most recent interview last year I was told I was on a 10 year ban because I overstayed my visa by a year and half and was over 18 years old. Even though I told the consular officer that my visa was under my parents passport and traveled at the age of 13 and left when I was 20 and had no choice but to wait until I had a stable situation before going back to Europe, I was still considered to have a 10 l-year ban.
Not knowing I had the 10-year ban, I still went back to the States to visit my family at least 12 times within the last ten years and answered no and all questions on the ESTA since I didn’t know I overstayed my visa and that I had a 10-year ban.
Now I am in the process of re-applying again but I'm scared that the officer will ban me for life if they consider that I should have known.
What can I do to prove them that I had no idea so it wouldn’t affect my IR1 immigration visa?
Thanks for the help.
