I know this question was asked many times, and I read most of the answers, only my quest centers on the time that has passed since my overstay.
Briefly, my story is I visited the US as a tourist from Argentina in 1993, and being there I wanted to try the experience to live there for a while, rented an appartment, could get a basic job as a driver doing deliveries, and ended up living for about one and a half years. After that, and realizing living as an illegal was a deadend with no promisory future, I just picked my things, bought a plane ticket and departed in 1994 never to return.
Long story short, after almost 25 years, now I´m a professional, have a good situation and would just like to make a short vacation there.
Here´s my main doubt; I´m not sure if it´s convenient or relevant to mention my overstay when applying for a visa, considering after such a long time they may not have record of that; or do Customs keep records for that long, and could backfire me here at the Consulate, or upon arrival at the airport?
I add additional information To make things more interesting, I also have an italian passport. Since I am of italian descent I own the double citizenship. This passport grants me VWP, but that doesn´t guarantee automatic entrance, that´s why I chose to go with the argentinian one which needs a visa. I assume that having a visa makes entrance more likely since you underwent a previous official scrutiny; or does it not? Besides using a different passport could seem an obvious way to dodge that scrutiny and make it even harder.
