Thank you Sir for your response.
CGI> I tried to update with US Travel Docs. They said they cant do it since appointment has already been booked. Below is there response.
“In response to your question, our records indicate that a receipt is associated with a profile or an appointment is already scheduled. Therefore, we request you to continue with your appointment, letting the officials at the Visa Application Center know about the changes to be honored on the day of biometrics interview.”
So I am confused when should I let officials know before biometric interview or during the interview.
DS160> How does updating at Biometric center before interview works?
Should I show up early and visit which section to update?
