Apostille for South Korea

By Frank MetayerUpdated August 16, 2026

If you're sending a U.S. document to South Korea — an FBI background check for an E-2 teaching visa, a university diploma, or a marriage or birth certificate — you almost certainly need an apostille rather than embassy legalization. South Korea has been a party to the Hague Apostille Convention since the treaty entered into force there on July 14, 2007, so a single apostille from the correct U.S. authority is what makes your document usable in Korea. The work is in the details: getting that apostille from the right office, in the right order, and recent enough to be accepted.

This guide walks through exactly that — which U.S. documents Korean schools, employers, universities, and immigration offices commonly ask for; the federal-versus-state split that decides who issues your apostille; whether you'll also need a certified Korean translation; and how recent your documents must be. Everything below reflects the process as of 2026. Because treaty membership and government processing times can change, confirm the specifics with the receiving Korean institution or the issuing U.S. authority before you file.

Key takeaways

As of 2026, South Korea is a Hague Apostille Convention member (in force since July 14, 2007), so U.S. public documents are apostilled — not routed through embassy or consular legalization. Confirm current status before filing.
Route by issuer: federal records such as an FBI Identity History Summary go to the U.S. Department of State, while state-issued or state-notarized documents (birth and marriage certificates, notarized diplomas) go to the Secretary of State — or equivalent office — of the state where they originated.
The apostilled FBI background check for an E-2 English-teaching visa is the single most common Korea request, and Korean schools and immigration offices commonly want it issued recently — often within the past six months, though the window varies (confirm it).
A certified Korean translation is decided by the receiving party — school, employer, immigration office, or court. English FBI checks are frequently accepted as-is, while diplomas and vital records more often need translation.
Match each document to the office that actually issued it and complete any preliminary steps in order — the single habit that prevents almost every rejection.

Does South Korea Accept an Apostille?

Yes. South Korea acceded to the Hague Apostille Convention, and the treaty entered into force for the Republic of Korea on July 14, 2007. That means a U.S. public document destined for Korea needs a single apostille certificate rather than the older, multi-step consular or embassy legalization process. Once a competent U.S. authority attaches the apostille, Korean bodies that recognize the Convention accept the document without further authentication by a Korean embassy or consulate. Hague membership can change over time, so while Korea remains a member as of 2026, confirm current status with the receiving institution or the HCCH before you rely on it.

An apostille verifies the document's origin — the signature, the official capacity of the person who signed, and any seal or stamp. It does not certify that the content is true, and it does not translate the document into Korean. If you were preparing the same paperwork for a country outside the Convention, you would need embassy legalization instead; for Korea, the apostille is the finish line on the U.S. side.

Which U.S. Documents Commonly Go to South Korea

By far the most common request is the FBI background check (the Identity History Summary) for an E-2 English-teaching visa — the record that public-school programs like EPIK and private academies (hagwons) typically require. Close behind are education documents: university diplomas, degree certificates, and transcripts, usually for teaching, other employment visas such as the E-7, or graduate study and university admission.

Then come personal and family records. Single-status affidavits (often needed to register a marriage at a local district or ward office, or to support an F-6 marriage visa), birth certificates, marriage certificates, and powers of attorney for property or business matters are all frequent. Corporate documents — certificates of good standing, articles of incorporation, and board resolutions — appear when U.S. companies do business in Korea. Every one of these follows the same principle: identify who issued it, then send it to the matching apostille authority.

Federal vs. State: Who Issues Your Apostille

There are two separate tracks, and mixing them up is the leading cause of a rejected packet. Federal documents — an FBI background check and other records issued by a U.S. federal agency — are apostilled only by the U.S. Department of State's Office of Authentications in Washington, D.C. A state office cannot apostille a federal document.

State-issued or state-notarized documents — birth and marriage certificates, notarized diplomas, single-status affidavits, powers of attorney — are apostilled by the Secretary of State (or the equivalent office, such as a Lieutenant Governor in a few states) in the state where the document was issued or notarized. A birth certificate from California goes to California; a diploma notarized in Texas goes to Texas. Some documents also need a preliminary step — a notarization, a county clerk certification of the notary's signature, or a state vital-records certification — before the Secretary of State will apostille them. We're experienced with both federal and state Secretary of State apostille processing, and can help you identify the correct track for each item.

FBI Background Checks for E-2 and Teaching Visas

For most people, "apostille for South Korea" means one specific job: getting an FBI Identity History Summary apostilled for an E-2 visa. The sequence is to (1) obtain the FBI check — many applicants use an FBI-approved Channeler for quicker results than mailing fingerprint cards directly to the FBI — and then (2) send that federal record to the U.S. Department of State for the apostille. Because it is a federal document, it never goes to a state Secretary of State.

Recency is critical here. Korean immigration and many schools want the FBI check to be recent — commonly issued within the past six months of your application, though the exact window varies by program and reviewing office (as of 2026; confirm it with your recruiter, school, or the Korean consulate handling your visa). Running the check too early can get it rejected even when it carries a valid apostille. Because federal apostille processing times fluctuate with backlogs, request the check with enough runway for the apostille and international shipping before your contract start date.

Do You Need a Certified Korean Translation?

The apostille and the translation are two different things. An apostille authenticates the U.S. document; it does not put the document into Korean. Whether you also need a certified Korean translation is decided by the Korean party receiving it — a public-school program, a hagwon, a university admissions office, an immigration office, or a court — and some offices also specify how the translation must be certified.

In practice, an English-language FBI background check is frequently accepted as-is for E-2 visa processing, while diplomas, transcripts, and vital records are more likely to require a certified Korean translation for the receiving institution. The safest approach is to ask the receiving party exactly what they need before translating anything — and when a translation is required, keep the apostille attached to the original document and have the translation prepared and certified separately, so the authenticated record is never altered.

Recency, Order of Steps, and Common Mistakes

An apostille itself does not carry an expiration date, but the document underneath it can effectively age out of what Korea will accept — which is why FBI checks and some vital records are expected to be recent. Time your document requests to your actual filing date, not the reverse.

The order of operations matters just as much. Notarize or obtain the certified record first, complete any required county or state pre-certification, and only then apostille — reversing these steps forces a redo. And always keep the two tracks separate: federal documents to the U.S. Department of State, state documents to the correct Secretary of State. Matching each document to the office that issued it, in the right sequence, is the single habit that prevents almost every Korea apostille rejection.

Frequently asked questions

How long does it take to apostille a document for South Korea?+

It depends on which authority handles it. State Secretary of State offices vary widely — some turn documents around in days, others in weeks — while federal documents going through the U.S. Department of State's Office of Authentications can take considerably longer, and those times shift with backlogs (as of 2026, confirm current processing times before you file). If your Korean deadline is fixed, such as a visa interview or a contract start date, build in buffer for issuing the underlying record, apostille processing, and international shipping. Many state apostilles can be expedited; ask about your specific document and timeline.

How much does an apostille for South Korea cost?+

It depends on the document, the issuing authority, and how fast you need it. You get a flat, all-in quote before any work begins — with no hidden fees, and no obligation.

Which authority issues an apostille for documents going to South Korea?+

It depends on who issued the document. Federal documents — most importantly an FBI Identity History Summary (background check) — are apostilled by the U.S. Department of State in Washington, D.C. Documents issued or notarized at the state level — birth and marriage certificates, notarized diplomas, single-status affidavits, powers of attorney — are apostilled by the Secretary of State (or equivalent office) in the state where they originate. No single U.S. authority apostilles everything; each document routes to its own office. We're experienced with both federal and state Secretary of State apostille processing.

Do I need a certified Korean translation for South Korea?+

Sometimes. The apostille certifies the U.S. document's origin, not its language, so whether you also need a certified Korean translation is decided by the Korean body receiving it — a school, employer, immigration office, or court. English-language FBI checks are often accepted for E-2 visa processing, but many institutions request a certified Korean translation of diplomas, degrees, and vital records. Confirm the requirement with the receiving party first, and if a translation is needed, keep the apostille attached to the original document.

What is the most common mistake with Korea apostilles?+

Sending a document to the wrong authority — for example, taking an FBI background check to a state Secretary of State (which cannot apostille a federal document) instead of the U.S. Department of State. The other frequent misstep is recency: Korean schools and immigration offices often want an FBI check issued within the past six months, so a check run too early can be rejected even after it is apostilled. Order the underlying record close to when you will actually file, and match each document to the office that issued it.
