Different Birthdate on Passport and Marriage Contract - I-130

[dyoan]

Hi all,

I am preparing my petition for I-130 for my parents. But i found out just now that my father's birth year is different on his passport from the marriage contract.
Passport - 1950; Marriage Cert - 1951
Will this small detail matter?

I believe this is just a typographical error.

I hope somebody could help me.

Thank you.
