What should I do if my Brazilian passport and my Chinese ID card are notarized and authenticated by the same person?

China does not recognize dual nationality, which means that for those who immigrate abroad, their domestic identities will be cancelled. Domestic real estate will be registered with their previous Chinese identities, and they will return to China to handle domestic real estate matters. In this case, the parties will be required to issue a certificate of the same person, proving that the Chinese ID card and the foreign passport are the same person's statement. There is no direct issuing agency for the statement, and you need to do it yourself. Draft a statement.

Authentication of the declaration of the same person in Brazil: first submit it to the Brazilian notary office for notarization, then submit it to the Brazilian Ministry of Foreign Affairs for authentication, and finally send it to the Chinese Embassy in Brazil for authentication. Certification time takes 7-15 working days.
