Taiwanese nationality is based on the principle of jus sanguinis - passed on by blood. If your parents are Taiwanese nationals it is very likely you are too, automatically.
However, there is an important conceptual difference in Taiwanese citizenship compared to that of other countries. Essentially, Taiwan only has the concept of a “national”, and what most of us think of as the rights of a citizen are tied with what is known as “Household Registration”. Nationals with full residence and voting rights are known as “Nationals with Household Registration”.
There are many Taiwanese nationals living overseas, who may be unaware they are Taiwanese, because they do not have the right to live or work in Taiwan without taking some additional steps.

If you are a National without Household Registration (NWOHR) seeking full citizenship, you must apply for a TARC and reside in Taiwan for:
