South Korea's electronic visa transfer failed.

I would like to ask "what should I do if the transfer of electronic visa in Korea fails?" This situation appears again.

It is recommended to understand the communication after receiving the notice of refusal, understand the reasons for refusal, and see if there are other referees and supporting materials. You can prepare more detailed, comprehensive and true materials and resubmit them to the Korean Immigration Bureau. Of course, the application for visa change cannot be successful at one time. Before reapplying, it is necessary to carefully review the reasons for the previous rejection and make specific improvements.
