yes. Russia-Ukraine-Belarus csc refers to the public application for studying abroad. The public application for studying abroad must be provided and signed by the foreign tutor and himself. If the foreign tutor cannot sign for special reasons, it can be reviewed and signed by the domestic tutor or relevant experts. Only in this way can the authenticity of the application for studying abroad be guaranteed. If there is no tutor's signature, it will be returned to the processing and requested to be re-signed. Therefore, the Russian-Ukrainian csc will return it and ask the tutor to sign it.
