Hi, I had booked my H1B stamping for Jan 28th. I have mentioned my intended date of travel as Feb 20 in DS-160. I couldn't make it to the interview and also my travel plans had been postponed. Hence I'm planning to reschedule my appointment for Feb end. In that case, should I submit a new DS-160 with a change in intended date of travel or Is it fine to proceed with the existing one ?
