What is the difference between ESTA and a visa?
ESTA is an electronic travel authorization for eligible nationalities traveling under the Visa Waiver Program for short business or tourist stays, not a visa itself. A visa is a separate document issued by a US embassy or consulate, required for travelers who are not eligible for the Visa Waiver Program or who plan to stay for purposes it does not cover.
