How much does it cost to legalise a Diploma for the South Korea embassy?

Embassy consular fee สอบถามเจ้าหน้าที่ + Thai MFA legalization (THB 200–400) + certified translation (THB 800–1,500/page) + NYC Legal service fee สอบถามเจ้าหน้าที่ — typically THB 6,000–12,000 all-in.

How long does the South Korea legalization take?

Thai MFA 2–3 days + Embassy of South Korea 5-10 วัน — 7–21 business days end to end, with express options where the mission allows.

Do I need the Thai MFA stamp before the South Korea embassy?

Yes — every Thai document must be legalised by the Department of Consular Affairs (Chaeng Watthana) before the Embassy of South Korea will authenticate it.

Does the Diploma need to be translated first?

In most cases yes — the Diploma must be translated into a language the South Korea mission accepts, certified by an MFA-recognised translator, then legalised together with the original.

What is a legalised Diploma used for in South Korea?

Visa and immigration filings, marriage, study, employment, pensions and legal matters. Popular documents at this mission: Apostille, Notarized Translation, Police Check.

Can I apostille a Thai Diploma instead of using the South Korea embassy?

No. Thailand is not part of the Hague Apostille system for this route, so a Thai Diploma for South Korea must go through Thai MFA legalization and then Embassy of South Korea authentication — not an apostille.

Do I need to appear in person at the South Korea embassy?

In most cases no — NYC Legal submits and collects on your behalf with an authorisation letter. A few document types (e.g. certain declarations) may require your signature, and we will tell you in advance if so.

How recent must my Diploma be for South Korea?

Many missions expect the underlying Diploma to be issued within the last 3–6 months. We confirm the current requirement for the South Korea embassy at booking so you don't legalise a document that will be rejected as stale.

What does a legalised Diploma for South Korea cost in total?

Typically THB 6,000–12,000 all-in: South Korea consular fee (สอบถามเจ้าหน้าที่), MFA legalization (THB 200–400), certified translation (THB 800–1,500/page) and our service fee (สอบถามเจ้าหน้าที่). You get an exact quote up front.

Can you ship the finished Diploma outside Thailand?

Yes. We deliver a scanned PDF immediately and courier the legalised original by EMS or DHL to any address in South Korea or worldwide.

Legalising a Thai Diploma for South Korea

A Thai-issued Diploma is a domestic document until it is legalised for use abroad. For South Korea, that means a two-tier authentication: the Department of Consular Affairs verifies the translator's and issuing officer's signatures, then the Embassy of South Korea confirms the MFA stamp. NYC Legal handles both tiers, tracks each counter, and returns your document ready to file.

Why the legalization chain is required

Each layer in the legalization chain authenticates the layer beneath it. The certified translation is verified by the translator's declaration; the MFA authenticates the translator's registered signature; and the Embassy of South Korea authenticates the MFA. Break the chain anywhere and the South Korea authorities can lawfully refuse the Diploma, even if the underlying facts are correct.

Certified translation requirements

Translation is not optional cosmetic work — it is part of the legal instrument. For South Korea, the Diploma translation must mirror every seal, marginal note and signature block of the Thai original. Our translators reproduce the full layout, then attach a signed certificate of accuracy that the Legalization Division will authenticate.

Transparent, itemised pricing

Costs are itemised, never bundled opaquely. Expect the South Korea consular fee (สอบถามเจ้าหน้าที่), the MFA legalization fee (THB 200–400 standard), translation (THB 800–1,500/page), and our handling fee (สอบถามเจ้าหน้าที่). We quote the exact total up front — including courier — so there are no counter-side surprises when your Diploma reaches the South Korea mission.

Realistic timelines you can plan around

Plan for 5-10 วัน at the South Korea embassy stage, on top of 2–3 business days at the Thai MFA and 1–3 days for certified translation. Realistically a single Diploma takes 7–21 business days end to end. If you have a visa interview or filing deadline, tell us first — express MFA and priority embassy handling can compress this materially where the mission allows it.

What a legalised Diploma is used for

A legalised Diploma is commonly required by South Korea for immigration and visa applications, marriage registration, family reunification, university admission, employment and work authorisation, pension and social-security claims, property or inheritance matters, and company registration. The most requested documents at the South Korea mission include Apostille, Notarized Translation, Police Check.

Common mistakes we help you avoid

Rejections usually come from small, avoidable errors: an expired Diploma, a translation that omits an official annotation, a name that reads differently from the passport, or a document submitted to the South Korea embassy out of sequence. We verify document freshness, translation completeness and stamp order before anything is lodged.
