H1b Visa Extension: which is better: Dropbox@Chennai or attend Visa Interview in Jamaica/Canana

Hello,

I need to go to India this November. I am eligible for drop box as I am staying with the same employer since last stamping and my current visa is expiring by coming october. I am working in EVC model in the same location of my employer and will have all proper employer & client documents.

Would like to know, what is suggested in my case? Using drop box facility @ Chennai or going to Jamaica and get it stamped in advance. How risky is drop box facility and is drop facility really a good option for me?

Thanks

Can anyone provide some suggestion?

I can not comment about Jamaica. But shall suggest availing drop box facility in chennai. 90 % chance is - you will get visa in 1 week without interview
