Is that your daughter or your wife's?

No, my question is different.

Is that your daughter? Or is that your wife's daughter? Or is your daughter both yours and wife's?

In other words, who are the parents of your daughter?

both mine and my wife's

You can apply under F2A category. It will take 3-5 years.

You don't need to get married to your wife (not really wife yet! Fiance or whatever.)
