Wrong date of birth in I797

[visa_121]

Hi,
I received I797 from my employer recently but my year of birth is WRONGLY mentioned in I797. My employer told me that the attroney filled it incorrectly at the time of submitting my petition. My H1B visa interview is scheduled on next week. I'm really worried & don't know what to do.

I would really appreciate if someone help me out & let me know what to do now.

Thanks,
