Petition wrongly approved - request assistance

Hi,

I had applied for H1B New. My petition was filed on Oct 2011. On May 2012 I had my petition approved but it was wrongly approved for H1B extension. The amended notice which I received again on July 2012 was again wrongly approved for H1B extension. The legal team in our company is asking us to go ahead for the interview with this petition approval notice. Will I be facing any issue during the interview? Has anybody experienced this issue before? If yes what was the solution?

Kindly assist me.

You need to contact the USCIS and get it changed. Better to do before you go for Visa stamping. Please check with legal team they are the better person to help in this situation.
