I just wondered if it was a big problem that my wife's birthplace is different on marriage certificate from her birth certificate with regards to the spousal visa application?

Could we leave it as it is or do we have to make changes now before submitting our application?

If we have to make changes, how would we go about that? Do we have to go back to the NSO again?

Thank you so much in replying to this thread, any help would be greatly appreciated!
