The amended law also stipulates that foreign spouses who get a divorce after suffering from domestic violence and never get married again or those whose Taiwanese spouses have passed away but who still live with and take care of other family members, can stay in Taiwan and remain eligible for naturalization.In addition, the amendment will no longer require naturalization applicants to first renounce their citizenship in their home country. Instead, they can provide proof that they have abandoned their original nationality within a year after they become naturalized in Taiwan.
