Let's start with those with foreign fathers and local Taiwan mother's who were locked out when the change came. Not all benefited, as Tommy per example. The leeway given was not enough. Since this law changed and people with -gasp- foreign fathers can be citizens of ROC, please give them expedited double nationality.
Maybe, in my fantasy land, someday, somehow, the kids who have been born here to foreign parents but lived 20 years or nmore and who are as fluent in taiwanese as any market ama and as knowledgeable in Mandarin as their peers, might be given a chance to stay as citizens and not given the boot and end up separated from their families.
