I'm using the cbp one app to apply for for the I-94 via land and it's asking me for a Visa Number and the Visa Date of Issuance, would that be the A number on my waiver? If it’s not I don’t know how they would know I have a waiver.
Does anyone have any experience using the app to cross, is it worth doing or should I just cross the usual way and go into secondary to get my I-94?
