In a couple of days I am going to fill out the tdac online. I am on a non-o based on retirement one year extension with a multiple entry permit. I am going to use the Visa input box on the tdac in lieu of an ongoing ticket. I want to use the Visa number off the multiple entry permit that I'm curious as to which number to use as there are two numbers. One number is part of the stamp and in the same color and the other number is a handwritten ink number. I'm assuming that this handwritten black ink number is the actual Visa number. Can you clarify this for me anybody. Thank you in advance
