H1 Stamping in India

Hi,

I have scheduled my H1 stamping date in Aug'24 but have some question as it's been almost 10 years that i have not visited India or updated my stamp (I797 has always in updated during this time).

Background: entered US on Oct'2014 and passport visa stamp expired in 2017 but i continued to stay on approved I797 and now after 10 years going back to India for stamping. I have approved I140 PD: Jun'2016

question: I have scheduled my appointment for Aug'24 but it came in as dropbox only even though i was expecting an interview considering visa was expired 6 years back.

• I heard that drobox location doesn't matter and i can drop my documents un New Delhi which eventually gets mailed to Chennai (central processing location).
• Also, i want to hear some experiences from folks who have similar cases or have recently stamped visa.

Advance thanks to everyone
