9. How long will it take to get mt interview date after submitting D160 form?

DS-160 is just a supporting document for visa. It is not a
application for the booking a visa appointment date. If you
want to book a visa appointment please follow the below like
with the DS-160 form bar code number:

https://www.vfs-usa.co.in/ApplnForms/RegularUser.aspx

After going into the website please select a link
accordingly and proceed. After filling the DS-160 there is
no guarantee about when you will get the visa appointment.
It depends on availability of visa appointment date. You can
also check the visa availability in the below site.

On booking the visa appointment date you will immediately
get a conformation letter about the visa appointment. Please
take a print out of both visa appointment conformation
letter and DS-160. I am not sure if you have made the
payment for visa appointment. Just in case if you did not
make the payment, you can make it HDFC bank and you will get
a receipt with bar code. Also keep the code safe. You need
visa appointment letter, DS-160 form and HDFC receipt along
with the required documents for visa while attending the
visa interview.
