How to apply for household registration in Taiwan Province Province when adopting a child in Chinese mainland?

With the approval of the Immigration Department, the applicant applies to the mainland public security unit for cancellation of the account with a copy of the residence certificate issued by the Immigration Department. After obtaining the certificate of account cancellation, you should go to the mainland notary office for notarization of account cancellation and submit it to SEF of Taiwan Province Province for verification. After children from Taiwan Province Province enter Taiwan Province Province with a residence permit issued by the immigration department, they should submit to the immigration department a notarial certificate of cancellation of household registration verified by SEF and a certificate of health examination in Taiwan, renew the original residence permit, and then register with the household registration authority where the household registration is located with the residence permit. (2) If the woman is pregnant before marriage and her children have been registered in the mainland, in addition to the above-mentioned relevant certificates, Taiwan Province DNA should also be provided, that is, the paternity test certificate (re-examination in Taiwan Province Province) and the health examination certificate in Taiwan Province Province (the form is obtained from the entry-exit department) (Note: children under 6 years old should prepare vaccination certificates); (3) Both parents are unmarried, the biological father is a resident of Taiwan Province Province, and the children have been registered in the mainland. First, the notarial certificate of the birth of the child, the notarial certificate of the woman's marital status, and the notarial certificate that the custody right belongs to the biological father shall be handled at the Chinese mainland Taiwan-related notary office.
