I was given a 221g blue slip in the month of Sep 2016 and i submitted additional documents. After a long period of nearly 9 months i got an email with another white 221g with the option "Submit your passport at your nearest application center’. Does it mean that it is approved? The reason i am asking is i am currently on H4 and in the US. I have to travel to India to get the H1B stamped. So want to make sure that it is approved before i make the travel plan. How soon should i be there to submit my passport after i got this notice? Please advise! Appreciate your time!
