I recently got an approval of H1B, but the name mentioned in the approval notice has a spelling mistake, instead of ashwani it is ashwini .

Do we have to get the same corrected before appearing for the interview ?? If yes, what is the procedure.

Does it make any difference when attending the interview as all other places including the passport , certificates and in my filling papers its the right name mentioned.

Please HELP >>>>>>
