anyone done H4 at mumbai consulate recently

[jk8]

Has anyone done H4 at mumbai consulate recently?
what is the exact process?

I have heard conflicting reports like -
- one can use drop box
- one has to go through VFS
- one has to go personally if its a first time.
- etc etc

Can someone please tell me what is the process to get H4 done at mumbai consulate? How long does it take? etc

Thanks
JK
