Unfortunately it will not work out well for lots of mix raced kids, I guess many don't even know who the father is, although they will be known as half/half,
I personally know of two, me and the wife have been friends for many years, the daughter is now about 16 and her father died when she was young, he was from Holland, they had done nothing about any documents when she was born, I remember the mother talking to my wife were she stands on getting a passport for the daughter I said as far as I am aware she is entitled to one if you can prove who the father was, she still had all the the documents and death certificate, the mothers English is not good so she needed my wife, my wife contacted the Dutch embassy fair play to the embassy they were really helpful once we provided all the documents needed as proof they issued a birth certificate and passport, her mother has the brains to keep it valid, but she doesn't speak a word of Dutch and I'm not sure how good the daughters English is haven't seen her for a while.
