Curious if you've figured this out at all? I'm an American-born Taiwanese. Both my parents are Taiwanese citizens. I don't have a Taiwan passport (my parents gave it up), and I've never lived in Taiwan long-term. However, I'm interested in getting citizenship/residency there if the path isn't too difficult. I'm leaving corporate life at the end of this year and planning to take the family to Taiwan for 2020 (3 months? 6 months? a year? depends on how my partner fares). From a cursory look online, it looks like if you have parents who are Taiwan citizens, and you live there for one year, then it's possible to get citizenship/residency.
