WORRIED! Will this be a problem?

[∞♥ 17]

This is probably a common problem, but here goes.

When I submitted my I-129F I used the names that were on my fiancee's current (at that time)birth cert. 2 months after we submitted it, we found out that her place of birth and the names of the parents were incorrect (they didn't use their full names.) Her mother goes by a name that is not her real name and that is what was on the original birth cert. We got all of that fixed earlier in the year.

Will this be a problem when we list her real full name on the DS-157? Should we write a letter explaining why it was listed as it was on the G-325A?

What is the worst case scenario?

Thanks in advance.
