If I recall correctly, a child born abroad of one parent who is a U.S. Citizen is a U.S. Citizen by birth.Thanks, I'll check it out i have jump through hoops just to get my daughter here. I was born in Oklahoma and served in the ARMY. But the means absolutely zero.
Is your name on her birth certificate?
This shouldn’t be about your getting her citizenship. This should be about your registering with the U.S. Government that your daughter is a U.S. Citizen.
If she is an adult, she can go to the US Embassy and provide them with the documentation, and they should be able to issue her a U.S. passport.
