Difference in date of birth in I-130

[gineshpg]

Hello Members,

                       I have filed I-130 for my brother around 12 years back. I just received notification from USICS that they are starting green card  processing now. But there is a difference between the date of birth of the baptism certificate that I submitted for I-130 and his passport. The difference is of just 2 days, but still it is a difference. He has an India Govt issued birth certificate and passport with same date. Is it too late to correct it? If not, what is the procedure for that? Current priority date can be maintained even after the correction?

 

Thanks!
