Chinese descendant applying for NWOHR

Hello,

I would like to inquire regarding my eligibility for NWOHR Taiwanese citizenship.
I am a US citizen of mainland Chinese descent, and do not hold household registration in China.

Is it possible for apply for NWOHR citizenship, and if so, how should I go about claiming it?
If it is relevant, my paternal great-grandfather held Taiwanese citizenship.

Thank you in advance.

do you still have PRC nationality? And. Do you read mandarin?

Thank you for the reply, tando.
I read Mandarin and I do not hold PRC nationality, though I was born in the PRC. I obtained US citizenship through the naturalization of not myself, but my parents.

then, this seems not to be applied to you.

Thank you for the link. I looked through the thread, but this procedure is all so confusing!

Do you mean that if I did hold PRC nationality, I would qualify for a ROC passport as well?

Sorry, I forgot to paste a link about it. The post was edited.
