Hi ​@한승희  - I acknowledge and understand that your school advised you to move your education verification to your school email.

I know that this answer will not be what you want to hear, but If you receive a “Verification Limit Exceeded” message, SheerID will have to assist you. They have an improved process for handling these errors, and are best equipped to review your case and advise on next steps. Even if you've contacted them before, their updated system ensures a more efficient resolution. 

Figma (including us, the forum moderators) cannot review documents or confirm individual user eligibility.

When you say you’ve already contacted SheerID, do you mean that you’ve submitted their help form, and are still waiting for a response? If that’s the case, please give them some time to get back to you. Due to higher volume, there are delays in response time.

One thing that may ease your worries: 

Figma has extended a grace period for students and educators currently reverifying their education status. At this moment, you will not lose access (or you should not have lost access) to your account or files on September 29.

Thank you for your patience. We’re focused on ensuring coursework and project deadlines are not disrupted.

I’m sorry I don’t have a faster solution, but I do hope this helps a little bit.
