Plans are already underway to issue US-authorized & approved ID cards to native Taiwanese persons. I started a thread about this on forumosa.com, however it was quickly taken over by the “peanut-gallery” types who specialize in satire and ridicule.
Validity of US-issued ID cards for native Formosans
The issuance of these cards would be the first step in providing internationally recognized ID documentation, issued by a sovereign government, for the Taiwanese people.
Contrary to some newspaper reports of late, the United States will not be granting “visa free” treatment to holders of the (non-sovereign) Republic of China passports.
