B1/B2 Visa Name wrong

[umailkiran]

Hi,
I have booked an appointment today over the telephone and have got the NONIMMIGRANT VISA INTERVIEW CONFIRMATION letter. But my first name was spelt wrong. The guy over the phone has very strong northern uk accent and I struggled to give all the information to him. I did mention to him over the phone that I am having a bit of problem understanding. Though he repeated every spelling back, it's a shame my first name is spelt wrong. Is it possible to correct the spelling after the confirmation and payment of fees. Or is it ok as other information reflects my name correctly? As you might know, it is ridiculously expensive calling 09 number.

Any advice is much appreciated.

Thanks,
Kiran
