My experience closely mirrors that of @monk_yatso, with the key difference being that my appointment was scheduled for 9:45 AM, and the entire process took approximately three hours to complete. During the interview, I was asked about my highest qualification, the institution where I obtained it, my field of research, any previous visits to the USA, and my intended place of stay in the country.
I’m pleased to share that our IVs were approved, and the status has now been updated to 'Issued' on the CEAC website. Wishing the best of luck to everyone still waiting, and a big thank you to those who continue to share valuable insights on this page!
