Quick Facts
Eligibility
Taiwan citizenship by descent is governed by Citizenship by descent · household registration. Taiwanese citizenship by descent operates under the Household Registration system. Children of Taiwanese nationals born abroad may claim citizenship through household registration. We file through the Household Registration Office and Taiwanese consulates.
Eligibility for Taiwan citizenship by descent depends on three key factors: (1) the generational distance between you and your Taiwanese ancestor — most Taiwanese programs cover up to parent (2nd generation), but some go further; (2) whether the citizenship line was broken by naturalization in another country before the next child's birth in the line; and (3) the specific statute in effect at the time of each birth in the line.
Ancestra's written eligibility opinion addresses all three factors for your specific case, citing the exact statute and consular venue that applies. Our genealogists specialize in recovering the civil registry, parish, and consular records required to establish the unbroken lineage that Taiwanese nationality law requires.
The 5-step process
Discovery & eligibility memo — Ancestra conducts a private 90-minute consultation, reviews what you know about your Taiwanese ancestry, and delivers a written eligibility opinion citing the specific statute that applies to your case.
Genealogy & document recovery — Our network of genealogists retrieves the Taiwanese records from the relevant civil registry and parish archives, plus the destination-country naturalization (or no-record) documentation.
Advisory & strategy — With documents in hand, we re-confirm eligibility, identify any discrepancies (name variants, date conflicts), and choose the fastest filing venue for your Taiwan case.
Dossier compilation — Our paralegals compile the application binder in the exact format the Taiwanese consulate or ministry requires, with translations, apostilles, and cross-reference indexes.
Submission & representation — We book the consular appointment or file with the ministry, attend with you (or by power of attorney), draft every RFE response, and stay with you through the oath ceremony and passport issuance.

What documents do I need for Taiwan citizenship by descent?
You'll need: certified long-form birth certificates for each person in the line, marriage certificates (and divorce/death where applicable), the Taiwanese ancestor's birth certificate (retrieved from the civil registry or parish of their commune of origin), naturalization records (or a "no record" letter), apostilles on all foreign documents, and certified sworn translations. Ancestra retrieves most of these documents on your behalf.
