10 years ago I went to the US on an Aussie passport and left well within the Visa Waiver period. The 2nd time I went that same year, I entered on a European passport and overstayed 4 months due to illness and other disasters. If I try to re-enter US to transit through to Central America, when they scan my Aussie passport, will they be able to link it up with the European one, or will they only be able to see the activity on my Aussie one only?? Thank you for any advice.
