And it's basically the same deal, except you need to add getting a criminal record check and a few steps, including:
1. Applying for Candidature and pass the language prerequisite.
2. On receipt thereof, apply for renunciation.
3. After that, apply for a TARC.
4. Wait a year - Apply for an ID Card.
I didn't want to do almost the same thing twice, so didn't bother with the APRC. But if you're already on an APRC, that may be enough, because otherwise you would have to be on an APRC for five years before you can start, and then it will take another 2-3 years to complete.
Taiwanese citizenship isn't for everyone. Depends what your future plans are. I would think about it carefully before committing to the process. I have a child here, and my country of origin is severally racially discriminitory towards people of my hue and only getting worse (now you can't even buy more than 49% of a franchise, or invest in certain companies anymore), and the SA passport is shit. The choice was easy for me. If I was American, Canadian, Australian, a New Zealander or even a Brit, I doubt I'd even still be here (not that I don't love Taiwan or anything).
Just my point of view. Use it, don't use it. :idunno:
