My mom is scheduled for b1/b2 OFC and VAC in Hyderabad later this month. However I had booked the appointment last year and since then the location has changed and date of visit has changed. Couple of questions -

1. Can I fill out a new Ds160 and make these changes without having to cancel or reschedule appointment?
2. I had filled out “self” as sponsor in the ds160 but she’s a homemaker so can I just put myself as the sponsor when I fill the new ds160? Or would it be a red flag?
   Thank you! I’d really appreciate any guidance anyone might have! 🙏🏼
