Taiwanese-born "tourists" When a foreigner marries in Taiwan, it isn't just the foreign spouse who must deal with residency and employment problems. Taiwan's citizenship law defines nationality strictly on the basis of paternity. When a Taiwanese woman marries a foreigner, her children are foreigners in the eyes of the law, just like their father.
異國婚姻除了配偶的居留權、工作權的問題外，由於台灣國籍法採父系認定，因此，台灣女性若嫁給外國人，生下的孩子必須跟隨父親的國籍，成為外國孩子。
