how to make changes with another DS 160 if already appoinment taken?


I have filled a DS 160 and appointed my visa interview for one university but I want to change to another university so that I have filled a new DS 160 and taken conformation. I asked to make changes in my profile with new DS 160 to the embassy but they said it is not possible bcoz you are already appointment taken. And they suggested to bring both DS 160 and let the officials to know about your changes on the day of OFC.

My question is: Is it possible to change on the day of OFC without any problem?

Well, all I can say that you have heard from the embassy that it can be done. I suggest you follow their advice and not worry too much. We have not come across such situation to advice you.
