Only the AICPA has the right to sign in Chinese mainland. Similarly, only AICPA in the United States has the right to sign, and only HKCPA in Hong Kong has the right to sign.
Third, the method of obtaining the right to sign contracts ACCA has also obtained the right to sign contracts in Commonwealth countries after passing the P7 test, and must have one year's work experience in the UK and obtain the British auditor qualification certificate (since there are other institutes of certified public accountants in the UK, ACCA is not the only certificate that can obtain the right to sign contracts in Commonwealth countries). The right to sign is not accompanied by a certificate. Generally, countries and regions have certain work experience requirements for the holder, so many people may not have the right to sign the certificate.
