Hi, in this situation I would submit the education-office email address and the official employment certificate together rather than relying on the school website domain alone.

If the @ai.jne.kr address is an account officially provided by the education office and is used by the teacher for their school-related Google Workspace account, that should be explained in the application, especially if the individual school does not provide separate email addresses.

For the employment certificate, an official document showing your name, school, position, current employment status, issue date, and the institution's seal would be the most useful evidence. I wouldn't arrange a certified translation unless GitHub specifically asks for one; you can mention that the original document is in Korean.

If the school doesn't appear in the application search, I would contact GitHub Education Support rather than trying to associate the domain yourself. Include the school's full name, education office, the official email domain, and the employment document details so they can tell you what they need to verify the institution.

I also don't believe being physically on campus should be assumed to be a requirement, but the safest approach is to follow whatever verification method GitHub presents for your specific application.

For anything involving personal employment documents, I'd submit them through GitHub's official support/verification process rather than posting the documents or personal information publicly in this discussion.

Hello! This is a very common scenario for public-school teachers in South Korea, as regional Office of Education domains (like @sen.go.kr, @ai.jne.kr, or @korea.kr) operate differently than university-specific email domains.

Here is the exact guidance for your situation, addressing each of your questions:

1. Education-Office-Issued Email Addresses

Yes, domains like @ai.jne.kr are valid educational emails and can satisfy the requirement.
However, because these domains are shared across hundreds of different schools in a province, GitHub’s automated system may not automatically link the email domain to the specific school you select in the dropdown.

What to do: Add and verify the @ai.jne.kr email address in your GitHub account settings before applying. If the application portal flags a domain mismatch, proceed by relying on the document upload feature to prove your affiliation with the specific school.

2. Korean Employment Certificates (재직증명서)

GitHub officially accepts non-English documents, but using a standard Korean employment certificate often causes automated rejections. This is because GitHub's Optical Character Recognition (OCR) system struggles to match a name written in Hangul on the certificate with a Romanized/English name on your GitHub profile.

The Best Solution: Obtain an English Certificate of Employment (영문 재직증명서). In South Korea, public school teachers can easily issue this official English document through NEIS (나이스) or Government24 (정부24). It will include your school name, position, dates, and official seal in English, which bypasses the OCR translation issues entirely. No third-party certified translation is needed if you use the NEIS/Government24 English certificate.

Note: Make sure your GitHub Profile Name (in your account settings) exactly matches the English name printed on this certificate before you upload it.

3. Registering a Missing School

GitHub Education pulls its institution list primarily from OpenStreetMap.
If your school is missing from the dropdown:

1. Type the full name of your school.
2. An option will appear allowing you to request the addition of the school.
3. You will need to provide the school's official website (typically ending in .es.kr, .ms.kr, or .hs.kr). Even if the school doesn't issue emails from this domain, the website acts as the official institutional record.

4. Physical Presence on Campus

Yes, physical presence on campus is critical. GitHub uses your browser's location services to verify that you are physically located at the institution you are applying for.
Applying from home or a cafe is one of the most common reasons teacher applications are instantly rejected for a "location mismatch." Please ensure you submit your application while physically on the school grounds, and ensure you are not using a VPN or iCloud Private Relay.

5. Private Support Channel

If your application is repeatedly rejected by the automated system despite following the steps above, you will need manual review.
The appropriate private channel is the GitHub Support portal. You can open a ticket specifically for education verification issues here:
[support.github.com/contact/education](https://support.github.com/contact/education)

When opening a ticket, explicitly state that your school uses a shared regional domain and attach your English employment certificate directly to the support request.

Recommended Workflow for Korean Teachers

To give yourself the highest chance of automated approval:

1. Issue an English Employment Certificate (영문 재직증명서) via NEIS.
2. Change your GitHub profile name to exactly match the name on that certificate.
3. Add your @ai.jne.kr email to your GitHub account.
4. Go to your school campus.
5. Submit the application from the campus network, uploading a clear photo of the English certificate.
