Ok, so I'm aware that my wife's kids can gain citizenship once she is naturalized (hopefully soon!). Does anyone know the process of getting the passport for the 2 minor kids and what, if anything, is required from their birth father? My wife has the Solo Parent ID and Affidavit, but there is no indication of sole custody in the annulment. Will we have to involve the birth father in order to sign off on getting them passports?
