How much does it cost to legalise a Diploma for the Mongolia 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 Mongolia legalization take?

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

Do I need the Thai MFA stamp before the Mongolia embassy?

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

Does the Diploma need to be translated first?

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

What is a legalised Diploma used for in Mongolia?

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

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

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

Do I need to appear in person at the Mongolia 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 Mongolia?

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

What does a legalised Diploma for Mongolia cost in total?

Typically THB 6,000–12,000 all-in: Mongolia 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 Mongolia or worldwide.

Legalising a Thai Diploma for Mongolia

A Thai-issued Diploma is a domestic document until it is legalised for use abroad. For Mongolia, that means a two-tier authentication: the Department of Consular Affairs verifies the translator's and issuing officer's signatures, then the Embassy of Mongolia 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

The reason the chain exists is verification of authenticity across jurisdictions. The Mongolia embassy will not read your Thai Diploma directly; instead it relies on the Thai MFA to vouch for the signature and seal of the Thai issuing authority (or the certified translator). This is why skipping the MFA step is the single most common cause of embassy rejection — the mission simply has nothing to authenticate against.

Certified translation requirements

Because the Mongolia embassy reads the translated text, translation accuracy directly determines acceptance. Names must match your passport exactly (including transliteration), dates must follow the destination format, and official Thai terminology must map to the correct Mongolia legal equivalent. We proofread against your passport and prior documents before submission.

Transparent, itemised pricing

Budget realistically: the Embassy of Mongolia charges สอบถามเจ้าหน้าที่ for authenticating a Diploma, the Thai MFA charges roughly THB 200–400 per document (express ~THB 800), certified translation runs about THB 800–1,500 per page, and the NYC Legal all-inclusive service fee is สอบถามเจ้าหน้าที่. A typical single Diploma therefore lands in the THB 6,000–12,000 range once every counter is paid.

Realistic timelines you can plan around

The Mongolia mission's own processing (10-21 วัน) is the least controllable part of the timeline, which is why we start translation and MFA legalization immediately and submit to the embassy the moment the MFA stamp is dry. Total realistic turnaround for a Diploma is 7–21 business days; we give you an honest date at quotation, not an optimistic one.

What a legalised Diploma is used for

A legalised Diploma is commonly required by Mongolia 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 Mongolia mission include Apostille, Mongolian Translation.

Common mistakes we help you avoid

Common mistakes with a Diploma for Mongolia: wrong order of stamps, an unverifiable translator, mismatched transliteration of names, missing supporting documents (e.g. a marriage certificate needed alongside a name-change record), and booking the embassy before the MFA step is complete. Our review catches these before they cost you a wasted counter visit.

Why work with NYC Legal

Our value is certainty. We know the Mongolia mission's current requirements for a Diploma, we use MFA-recognised translators, and we sequence the chain correctly the first time. That means no repeat consular fees, no missed deadlines, and a document your Mongolia counterpart will accept without objection.
