Dear Jim Henson,
Thank you for your attention to our website.
If customers apply with us and it is our fault: We will check and send you the correct E-Visa by your flight time.
If customers did not apply with us or apply with us but it is the customers’ fault: The E-Visa once issued cannot be amended. You need to apply for the new E-Visa to board the plane and enter Vietnam.
Best Regards,
Heidi Phan
