I need your help to assure me Now, I have completed the DS-160 and then created a profile to schedule the interview but in this profile I made a small error in my passport number. I contacted the technical support but no reply for more than 10days. All the other papers including DS-160 have the correct number, it is only the appointment letter that has the mistake. I was thinking of attending the interview and inform the consular officer there about this mistake and that I tried to contact the technical team. Do you think it will be fine? and that will not cause any problem to me? I am in a hurry.
