Your baby's hospital certificate records a birth. It does not tell you whether Taiwan household registration is complete or whether a U.S. passport can be issued. Before the first trip, work out the child's citizenship, then the records and travel documents that follow from it.
The facts that matter are the place of birth, each parent's nationality when the child was born, legal parentage and the Taiwanese parent's household status. They determine which filings you need.
Which citizenship can the child acquire at birth?
Article 2 of Taiwan's Nationality Act treats a child as a Republic of China national if the father or mother was an ROC national when the child was born, and it also covers a few other specified categories. Taiwan does not grant citizenship based on place of birth, except in narrow cases such as a child born in Taiwan to unknown or stateless parents. To have the child's status recognized on official documents, you will need evidence of the parent's nationality and of the legal parent–child relationship. For a child born outside marriage to an ROC father and a foreign mother, BOCA's first-passport guidance cited below requires the father's acknowledgment of the child to be registered before the child can apply for a passport through him. Any inconsistency in the parentage records also has to be cleared up.
For a child born outside the United States, the State Department's citizenship-transmission guidance sets out rules that turn on the parents' citizenship and marital status, parentage and the U.S. citizen parent's physical presence in the United States. Identify which rule applies before you start counting time spent in the United States. Having a U.S. citizen parent does not guarantee transmission in every case. The American Institute in Taiwan (AIT) will ask for evidence of the parent's U.S. residence and physical presence to decide whether the requirement was met.
When the baby is born in Taiwan
Check that the names, dates and other details on the hospital's birth certificate match the parents' records. The certificate is evidence you will use for government registration, not the registration itself. Registering a birth in Taiwan and completing initial household registration for a child born overseas are different procedures. The Department of Household Registration's guidance covers initial household registration, including the settlement-certificate route for children born overseas. Which procedure applies depends on the parent's actual household status.
If the baby acquired U.S. citizenship at birth abroad, a Consular Report of Birth Abroad (CRBA) documents that fact. The State Department's birth-abroad guidance explains what it is for. A CRBA cannot make an ineligible child a citizen, and it is separate from a U.S. passport. Check AIT's current application and appointment procedures in Taiwan.
When the baby is born in the United States
A U.S. birth certificate does not add the child to a Taiwan household record. The National Immigration Agency settlement guidance for nationals without household registration covers children born overseas in specified categories. The relevant conditions include whether the parent had household registration in Taiwan when the child was born, the child's age and the passport used to enter Taiwan.
Identify the category before assuming that the child can register right away or must first live in Taiwan for a set period. An eligible child first obtains a settlement certificate and must then apply for initial household registration within 30 days, counted from the day after the certificate is issued. These routes require a parent who was a national living in Taiwan with household registration there when the child was born. If neither parent met that condition, a different route has to be considered. Parentage and any required parental consent must also be documented.
For U.S.-issued documents, arrange authentication with the Taipei Economic and Cultural Office (TECO) that covers the issuing state, and ask the receiving office how the Chinese translation must be certified. Tell both offices the document type and the issuing authority so they can identify the authentication required before you order extra copies.
BOCA's guidance on first passports for children born abroad lists the documents needed for the application. Under item 7 of the NIA guidance, once initial household registration is complete, the child's first departure from Taiwan must be on an ROC passport showing the newly assigned national ID number, so apply for that passport before booking the flight out.
Registration status affects the travel documents
The child's citizenship and Taiwan household-registration status decide which passport applications apply. The State Department's passport guidance for children under 16 covers proof of citizenship, parental consent and the child's own application. A parent's passport, the hospital certificate or a pending CRBA cannot stand in for the child's own travel document.
BOCA's household-office identity verification guidance applies only to eligible applicants who already have household registration in Taiwan; not every child will have that status. Confirm the passports and entry documents each country requires before booking travel.
If the parents' marriage records still need attention, the U.S.–Taiwan marriage registration checklist covers that earlier step.

Frequently Asked Questions
- Does birth in Taiwan make every baby a Taiwanese national?
- No. Being born in Taiwan does not by itself make a child a national. Taiwan's Nationality Act generally looks to whether a parent was a Republic of China national at the child's birth, with a few other statutory categories. You will need evidence of nationality and legal parentage.
- Is a U.S. citizen parent enough to guarantee citizenship for a baby born in Taiwan?
- No. U.S. rules for passing citizenship to a child born abroad depend on the parents' circumstances, including physical-presence and parentage requirements. Ask AIT which rule applies to your child and what evidence it needs.
- Does a U.S. birth certificate automatically create Taiwan household registration?
- No. A child born abroad may first need a settlement certificate from the National Immigration Agency and then initial household registration. Eligibility depends on the parent's household status, the child's documents and other conditions.
