Thank you very much birbal sir,
i have talked to the Indian Embassy at Chicago, they said that they will add boora in a day but i am more worried to getting it changed in my VISA becoz i was told that u have to go back to india to get the change of name in your VISA.
Abhijit,
I am not aware of current American rules, but it may be possible to get the new name on Visa by just crossing the border to Canada (Toronto American Consulate). Of course, you will need to pay for the trip to Toronto, but it is not that expensive. Also, you will need a tourist Visa for Canada, but I can write a letter of invitation to you (required by Canadian Consulate) giving the true nature of the problem and I am sure they will process it quickly.
