name issue on the H1b Stamp

[mougli]

Hi all,

I got my H1b issued at the Chennai consulate last week. However, When I received my passport, I found that my middle name was wrong. I mean, My middle name is Sriramulu but It is been spelt as "Sri Ramulu". The difference is only the space.
Should I send it for restamping?
How long will it take for the restamping?
Is there any fee which I need to send?

Please help.

Thanks.
