US Visa Appt at Hyderabad - OFC vs Interview in H1B : Visa Stamp Posted January 17 · Report reply Hello I am trying to schedule my H1 visa interview at Hyderabad location in India. Website is showing options to select OFC appointment first and currently its giving me options till end of March only. On the left side of the page, it says first available appointment is April 15th. If earliest available interview appt date is April 15th, I would like to schedule OFC date only 1 or 2 days prior. So,should I wait till OFC dates for April open? I wonder if they open OFC dates only till a certain number of days like 2 months or something. Is it? Once I book OFC appt and interview appt, can I change them any number of times? And if I try to change, can I change any one of them or am I supposed to change both only? My spouse is on H4 and she is eligible for Dropbox. Can her appointment happen before mine? Please suggest. Thank you.
