I got H4 renewal Approval notice (I 797-A). My current H4 visa stamping is expired on passport. I need to travel to India and will need to get stamping again. What is the process for that? do I need to fill DS-160 again? I think it should be eligible for dropbox. Don’t understand the process for the same. Please guide me with steps I need to follow to be able to get stamping for H4 renewal in India.
