Proof Of Termination Of Marriage: Japanese Divorce At City Hall (Ward Office) Not In A Court

[Eric The Wait 40]

My fiancé is a permanent legal resident in Japan. She is a South Korean Citizen, but has lived in Japan for 30 years. She was previously married to a Japanese Citizen.
My fiancé was divorced in Japan 5 years ago through a purely administrative process. There is no Court decree. She obtained consent of ex-husband to divorce and filed it with the City Office and obtained the divorce. This type of Divorce is legal in Japan.
In the United States all divorces must go through a judicial process, not merely an administrative process. In other words, in United States one can only get divorced through a Court. It is my understanding administrative divorces such as a Japanese style Ward Office (City Hall) type divorces are not recognized here in the United States.
The I-129f requires proof of final termination of marriage by a divorce decree.
My question is this: For purposes of the I-129f will the Ward Office (City Hall) Divorce my fiancé obtained in Japan be considered acceptable such that my fiancé meets the "free to marry" requirement for getting a K1 Visa?

Yes. All 4 procedures of divorce in Japan are legal and accepted as Divorce Decree.

Thank you Maria4Garrett for your answer. I couldn't confirm whether beneficiaries from Japan with this type of divorce were able to get approved and receive the NOA2. I am still at the NOA1 stage. With the 1-129f we sent in only the ex-husband's family register which references the Divorce. I think we may get an RFE requesting something more so my fiancé just obtained the Certificate of Acceptance of Divorce from the City Ward where the divorce was filed. I was told to wait for the RFE before sending that in.
Anyway, I hope they consider her "free to marry" and thanks again.
