H1B renewal visa stamping dropbox in Pune?

[veeus18]

Hello, 

I was previously on H1B, which expired August 2017, and my current H1B was renewed until August 2020. This will be my first time using the dropbox option - I completed the online DS-160, and am in the process of making the payment. I was wondering if I could drop off the documents at the visa service center in Pune or do I need to go to Mumbai ? Please could someone share their experience.

 

thanks.
