Generally, a criminal conviction for a major crime such as fraud, would make a person pemanently ineligible for ESTA and also, in most cases, would make such convicted person permanently ineligible for a US visa, regardless of when conviction took place.
Failing to disclose such conviction on ESTA application would constitute visa fraud and not only make the applicant permanently ineligible to enter the USA, but can also subjce the applicant to a federal criminal prosecution for visa fraud.
I am very sorry to provide you with this bad news, but please understand that I do have professional obligation to provide JustAnswer.com customers with correct answers, even when answer is not favorable to the customer.
