ERROR IN DS160 - want to keep same interview dates.

[sreesanu]

Hi Guys,

I filled the DS 160 form and took the appointment for my parents. It's been done about 3 days back and I realised a mistake.

While selecting the field Purpose Of Travel from dropdown I selected - Tourism/ Medical Treatment (B2) for my mother and by mistake selected - Business/Personal(B1/B2) instead of selecting same as I have done for my mother.

Every document shows that the inivation is for both parents tourism.
1. Letter which i have written to consulate
2. Letter written to parents inviting them
3 Affidavit for I-134 form

How can I change the purpose of visit of my father to same as mother's. I want them to have the same interview dates as my wife is close for delivery due date

Thanks,
Sree
