I have a European Passport and I would like to try a student visa .?
Practically yes, your ESTA will be revoked if your visa application was denied. How it works is: while you have a valid ESTA, new travel authorization (requirement that you go back to the ESTA online system and reapply) is required in the followings instances: You obtain a new passport You change your name You change your gender Your country of citizenship changes The circumstances underlying the aliens previous responses to any of the ESTA application questions requiring a yes or no response (eligibility questions) have changed. One of these yes/no questions is along the lines of have you ever been refused a US visa. In practical terms, if there was a visa denial and an applicant applies for ESTA again in the future, they would likely be denied. That is, once someone is no longer eligible for ESTA, it is not likely that they will be eligible in the future. In order to travel to the U.S., a person that is not eligible for ESTA must apply for a B1/2 visa.
