I’m investigating the ins and outs of Taiwanese naturalization. It appears that part of the naturalization process requires the applicant to become stateless for a period.
Article 9 of the Nationality Act requires that a certificate of loss of original nationality be provided BEFORE Taiwanese nationality is granted.
My original nationality won’t allow me to renounce unless I first show proof that I have obtained another citizenship. That is, they won’t allow anyone to renounce their citizenship if it will make them stateless.
I always thought that after becoming a NWOHR you had one year to renounce your original citizenship, but not sure. Tando or someone with more knowledge will be around soon.
