I know several who have. A few of them have been forumosa members.
One started a thread on how to do so. Another one wrote a book about his military service in Taiwan. Another ran for election after naturalizing.
One did so as he wanted to head his own architecture firm in Taiwan which also required passing licensing.
Of course you not being knowledgable about these things is not surprising. So much of the discourse you offer on threads here has been proven to have a very limited perspective.
You remind me of another forum member who goes into threads to talk about the USA when the threads have nothing to do with the USA.
