I am going to India for my stamping via dropbox. The consulate is automatically selected as Kolkata for the visa processing in the interview waiver confirmation letter since my hometown is close to West Bengal. However, I would like to drop off my documents in Delhi. Is that possible?

Additionally, the DS-160 has the last question as "Location where you will be submitting your application" - Should I enter Delhi (where I will drop off my documents) or Kolkata (post selected for visa processing)?

Your help will be appreciated. Thanks in advance.
