The authentication of the highest academic degree is a crucial component when applying for a work permit in China as an expat. The degree can also be authenticated domestically, and the China Service Center for Scholarly Exchange, as the most authoritative official channel for academic credential authentication in China, provides a more convenient online process for both foreign individuals and employers. You can complete the online application by visiting the CSCSE online service portal at http://zwfw.cscse.edu.cn/.
