How does a traveler revalidate a visa without their I-94?
The I-94 admission record is created electronically and maintained in CBP systems. CBP will verify the I-94 electronically to re-validate an expired visa if the traveler meets the conditions of automatic revalidation. In order to demonstrate eligibility for automatic revalidation, a traveler may be required to present a copy of the website printout to the air or sea carrier prior to boarding. If entry occurred prior to automation, a paper form must be presented in order to comply with validation requirements. For more information about automatic revalidation go to http://www.cbp.gov/document/bulletins/automatic-revalidation-visas.
