B2 visa renewal

Hi,

I have applied for the renewal of my B2 visa expiring in May 2025. I am eligible for interview waiver, paid the visa fees.

While scheduling the visa appointment, the OFC slots available where in Delhi(I am based in Hyderabad)

My question is in the title it shows OFC appointment, but when I select dropdown it shows New Delhi - VAC. I don’t understand is this biometric or dropdown?

I also heard that for dropdown, you can drop off any of the VAC locations regardless of the appointment city, Can anyone please shed some light on this please.

Thank you!
