if your parent was a national with hhr when you were born, you don’t need to be on tarc to get your hhr.
- if you are a minor or born in taiwan, you can enter with foreign passport and register your hhr
- if you are born abroad and not a minor, you need to enter with a nwohr passport to register your hhr
if none of your parent is a national with hhr, it remains the same, or almost the same.
not sure if you want to add, but if you were born in prc, different rules are applied.
