Mark, I follow your story and your daughter is truly a bright girl. I watched the video and I was amazed of how smart she is. In place where I am currently living, birth certificate works to obtain any government paper issues but nothing related to tax paying. There are still many of citizens in my country who doesn't pay personal tax. Regardless, I believe that government has a right to take away children under hostile circumstances.
Best wishes to the family and the smart girl :) !
