H4 stamping in India while visa approved in US

My husband holds an H1B visa while I am on a dependent H4 visa. We bothhave been in the US since January 2014.In January 2015, my husband changed jobs and now our visas are in the nameof the new employer. But during this process I had to fly down to India dueto a family emergency and now have my H4 visa approved in the name of thenew employer but my visa stamp is of the previous employer.Could you please advise me if I can just use the DropBox for my new visastamping or do i need to go through the entire interview process onceagain? Also let me know what are the other options that I can consider ifthere are any.

You need to go through complete interview process as it is a new company for your husband.
