So there is no way he can get citizenship from your wife's country of birth?
For many countries you wouldn't even need to be involved or notified. If he has claim to citizenship in her country of birth, she could apply for a passport as proof of that citizenship (by descent).
Just want to make sure you have covered all your bases COD.
