美國依親移民結婚證書問題 - 移民

大家好，我幫父母申請依親移民，遞交的結婚證書被退件
我當時給的是戶政事務所的英文版結婚證書，
卻被說from the incorrect issuing authority
請問我應該如何修正這部份？

謝謝！

退件原文:
The document we received is from the incorrect issuing authority.
Please send a copy of the applicant's original marriage certificate,
or a copy of the certified marriage document, bearing the appropriate
seal or stamp of the issuing authority. If the certificate is a certified
copy of the original, it must come from the issuing government authority
and it must contain annotation by the issuing government authority
indicating that it is an extract from the official records.
