My husband is a citizen of Kazakhstan. Immigrated in 2004 and got a marriage certificate in China in 2008. Now I need my husband's cancellation certificate. Where can I consult?

When he applies for citizenship of other countries, he needs to report to the household registration police station to apply for cancellation, and then he will be issued with a cancellation certificate. If he had not taken the initiative to cancel his account at that time, the police station would not have issued this certificate. Once he is found to have a foreign passport, he will automatically give up his China citizenship, and the police station will not reissue his cancellation certificate.
