Diploma Apostille for South Korea Work Visa — China, Japan, Korea: Translation Rules

If you are preparing your university diploma for a skilled worker or employment visa application in South Korea, the document must first carry an officially recognized apostille. Without it, South Korea's receiving institutions — embassies, consulates, employers, universities or immigration officers — cannot legally verify that your record was issued by a competent authority. This page explains how the apostille works specifically for South Korea, who issues it, what other steps usually accompany it, and how DoCertify handles the entire chain on your behalf.

What this service includes for South Korea

Authentication authority for South Korea

Documents bound for South Korea are authenticated through the Ministry of Foreign Affairs of the Republic of Korea (MOFA). Because both South Korea and most likely the country where the document was issued are members of the 1961 Hague Apostille Convention, a single apostille certificate is sufficient — no embassy legalization is needed.

How DoCertify processes your diploma

  1. Free eligibility check. We confirm that your university diploma qualifies for an apostille from the Ministry of Foreign Affairs of the Republic of Korea (MOFA), and flag any pre-step (notarization, state-level certification) needed first.
  2. Document intake. You ship the original record to our processing office, or we collect it from your address by courier. Scans are accepted only for documents that the issuing authority will re-print on demand.
  3. Apostille issuance. Our team submits the document to the Ministry of Foreign Affairs of the Republic of Korea (MOFA), monitors the queue and retrieves the apostille — typically in 3–7 working days for standard processing, or 24–48 hours for urgent service where available.
  4. Certified translation (optional). If South Korea requires the document in another language, we add a sworn translation that satisfies South Korea's receiving authorities.
  5. Delivery. The apostilled document is returned to you with tracked international courier, or — when accepted — sent directly to your destination institution in South Korea.

Frequently asked questions

Do I need to be in South Korea to start the process?

No. The entire apostille chain is processed in the country where your university diploma was issued, not in South Korea. You only need to ship the original document to our processing office; the apostilled and translated package is then couriered to wherever you are.

Will my diploma be accepted by South Korea authorities?

Yes. The apostille we issue is performed by the Ministry of Foreign Affairs of the Republic of Korea (MOFA), the recognized authority for documents of this type. Receiving institutions in South Korea — embassies, consulates, employers and immigration offices — verify the document through the same channel.

Do I need to translate the document into South Korea's official language?

If your diploma is not in one of South Korea's working languages, a sworn translation is normally required in addition to the apostille. We can add a certified translation as part of the same order.

What is the most common reason South Korea rejects a foreign diploma?

Three issues account for most rejections: (1) the apostille is missing or was issued by a non-competent authority; (2) the translation was completed by a translator not recognized in South Korea; (3) the order of operations was wrong — for example, a translation produced before the apostille was added, leaving the apostille text untranslated. We sequence the chain correctly the first time.

Employers and skilled-worker visa officers in South Korea sit on dozens of applications per week. A document chain that arrives correctly authenticated and translated the first time moves through the queue faster, while a chain with a missing step is set aside and often only flagged after weeks of waiting. We process your university diploma so that the work-visa decision-maker can verify it on first inspection.
