If you already completed the U.S Dept. of State authentication by mail, we are happy to assist you with the authentication of the Chinese Embassy before Nov 30th, 2023.
The current processing time for the Embassy’s authentication is about 1 week. To start, please email your documents to our office for preview, we will provide you with the right forms and instructions accordingly.

The Chinese Embassy can still accept documents for authentication before Nov 30th, if your document is certified by the U.S Dept of State before Nov 7th.
Otherwise, we advise you to prepare your documents for apostille certifications.   Apostille certification only takes a few days to process, and cost much less.

Due to the extremely long processing time with the U.S. Dept of State authentication office, we decided to stop processing Federal authentication orders.   The U.S. Dept of State authentication office has been closed for the Pandemic and remaining closed since then.   For details, please visit the official website at  HERE


受国务院办理时间过久和政策调整的原因, 我们现价段暂停办理全套的使馆认证(即三及认证)服务。 我们建议等到11月中旬或下旬后根据政策的调整再办理海牙认证。

如果您已经完成了国务院的认证, 您可以将文件拍照发邮件给我们公司, 我们再根据您文件的情况提供办理使馆认证所需要的表格和信息, 以及费用。
