I recently used the dropbox facility for my second H1-B VISA stamping, at the US Embassy in Mumbai. The experience was a smooth one, and is definitely hassle free compared to the in-person finger printing and interview process. The requirements for using the dropbox can be found here, and the list of dropbox locations across India can be found here.The documents I submitted are as below:
1) I797 Copy
2) DS-160 confirmation printout
3) Dropbox confirmation letter
4) All previous and current passports.
5) One 2 X 2 inch recent photo (Please note, this photo has to be different from the one in passport even if it was clicked recently)
The whole process took about a week for me and here is the entire timeline.
Nov 23rd - Dropped off the document
Nov 24th - Case created - VISA status: Ready
Nov 27th - Case updated - VISA Status: Admin Processing
Nov 30th - Case updated - VISA Status: Issued and Passport ready for pickup
