Frequently asked questions about this case
How many steps does a medical certificate in Nakhon Ratchasima (Korat) take before it can be used in South Korea?
Based on how these files are usually handled, this type of file runs through 6 main steps, starting with "Establish how many layers of certification the Embassy of the Republic of Korea requires and which channel the destination embassy accepts applications through." and ending with "Run a final checklist before handover and flag the follow-up risks if the receiving authority asks for further documents.". The receiving body is the Embassy of the Republic of Korea, which checks both the content and the order of certification. Skipping a step usually means the file is returned and the process restarts.
Which documents do I need to prepare for this medical certificate case?
Prepare Original medical certificate · Power of attorney with ID copies of both grantor and attorney · Original Freshly issued civil registry document · Translation prepared in a format the Department of Consular Affairs can certify before the first step. Names in English must match the passport spelling on every document, and a freshly issued copy is safer when the receiving authority sets a validity window.
How long does the process take?
In practice, the working estimate is roughly 10–15 working days, depending on government queues and public holidays. Allow extra time when several layers of certification are required or when originals travel between provinces.
What most often causes this document to be rejected?
Company documents were not freshly issued by the Department of Business Development — the fix is: Obtain the latest company affidavit and confirm the authorised signing directors match the register. Checking this single point before filing removes the most common cause of a second round.
Can this be handled remotely from outside Nakhon Ratchasima (Korat)?
Yes. Most clients in Nakhon Ratchasima (Korat) send photos of the documents for a pre-check, then courier the originals. Our team files, follows up with the authority, and ships the finished documents back to the address provided.
Where can I verify the official requirements?
Following the order the authorities expect, verify with Hague Conference on Private International Law (HCCH) — Apostille Section (https://www.hcch.net/en/instruments/conventions/specialised-sections/apostille), which Contracting-party status and the legal effect of an Apostille certificate between member states.. Government fees and timelines can change, so confirm before filing.

Full service playbook — Consular & Embassy Legalisation
For countries that do not accept an Apostille, Thai documents follow a fixed chain: issuing office → certified translation → MFA legalisation → destination embassy. The order cannot be skipped.
Responsible authority: Department of Consular Affairs (MFA Thailand) and the destination country's embassy
Documents to prepare
- The original document issued by the Thai authority, or a freshly re-issued copy
- An English translation with the translator's certificate
- Passport or Thai ID copy of the document holder
- A power of attorney plus the agent's ID copy if someone files on your behalf
- The MFA application form and any extra embassy form
Step-by-step process
- 1. Confirm the destination's requirement1 business day
Establish whether the country wants an Apostille or full legalisation, and in which language.
- 2. Re-issue the source document1–3 business days
Many offices impose a freshness rule; obtain a new certified extract from the registrar or issuing body.
- 3. Translate and certify1–3 business days
Prepare the English translation with a certificate so it meets MFA acceptance criteria.
- 4. File with MFA Consular Affairs1–3 business days
Submit the application with original and translation; standard and express channels exist under MFA rules.
- 5. File with the destination embassy3–15 business days
Present the MFA-legalised file to the embassy; queues, forms and opening days differ by mission.
Practitioner tips
- Check embassy intake days in advance — many accept documents on selected weekdays only.
- Allow for both Thai and destination-country holidays, which rarely coincide.
- Scan every page to 300 dpi colour PDF before the originals leave your hands, in case a re-submission is required.
- Match the Latin spelling of your name to your passport exactly — receiving authorities compare character by character.
- Confirm whether the destination wants an original or a certified copy — the two follow different routes.
Cautions
- Going straight to the embassy without MFA legalisation is normally refused on the spot.
- An out-of-order chain forces a full restart of the process.
- Unsigned translations cannot be certified — the certifying office will refuse to stamp them.
- Multi-page documents must be certified on every page where the rules require it, not only page one.
- Copies made from copies are commonly rejected; use originals or copies certified by the issuing office.
DIY vs NYC handling it
| Task | Do it yourself | NYC handles it |
|---|---|---|
| Checking destination rules | You read checklists and call around yourself | We verify the current requirements and hand you one list |
| Multi-agency running | Several days off work, different queues and hours | We run the whole chain end to end for you |
| Translation and certification | You source a translator and risk rejection | Translated, double-checked and certified in one package |
| Errors and re-filing | One mistake restarts the whole chain | Pre-submission checks at every stage reduce rejections |
| Tracking | You chase the status by phone | Stage-by-stage updates on LINE with photo evidence |
Prefer not to run it yourself? NYC can handle the whole chain
Every step above can be done alone, but it means several agencies, mismatched queues, and one mistake restarting the sequence. Our attorneys and translators cover requirement checks, document re-issue, certified translation and MFA or embassy legalisation, with status updates at each stage. Send photos of your documents for a free assessment first.
Compare the options before you decide
Apostille route vs embassy legalisation route
The destination country decides whether a file ends at an Apostille or still needs the embassy. Confirm the country's convention status first: the two routes use a different order and different paperwork.
| Aspect | Apostille route | Embassy legalisation route |
|---|---|---|
| When it applies | Destination is a party to the Apostille Convention | Destination does not accept an Apostille |
| Final authority | Department of Consular Affairs, Ministry of Foreign Affairs | The destination country's embassy or consulate in Thailand |
| Typical number of steps | Fewer — the chain ends at the central authority | More — central authority first, then the embassy |
| Approximate timeframe | Shorter, still subject to the authority's queue | Longer, because the embassy appointment queue is added |
| Common rejection cause | Translation does not match the original, or the copy was not issued by the authority | The embassy's own form or language requirement was not followed |
Verify the current convention status and embassy conditions before filing.
MFA-certified translation vs NAATI vs a destination-country sworn translator
"Certified translation" does not mean the same thing everywhere. The receiving body defines the accepted form, and choosing the wrong one means translating the whole set again.
| Aspect | Translation + Thai MFA certification | NAATI / foreign sworn translator |
|---|---|---|
| Who certifies | The Department of Consular Affairs certifies the translation and the translator's signature | A translator registered with the destination country's body |
| Accepted by | Thai authorities and destinations that accept Thai certification | Bodies that explicitly require a registered translator, such as Australian immigration |
| Output format | A certification stamp on the translation attached to the original | The translator's statement with their registration number or stamp |
| Can an Apostille follow? | Yes, when the destination is a convention party | Depends on that country's rules; some require no further step |
| Check before you start | Whether the destination accepts Thai consular certification | Whether the receiving body requires its own registered translator |
Where the destination requires a court-registered sworn translator, Thai certification cannot substitute for it.
Filing it yourself vs letting NYC run the chain
Every step can be done alone. This table compares the real workload of each option so the decision rests on time and rejection risk rather than marketing claims.
| Aspect | Do it yourself | NYC handles it |
|---|---|---|
| Checking destination rules | Read each authority's notice yourself and confirm by phone | Checked before you start, with the order the receiving authority accepts |
| Travel | Several agencies with queues that rarely line up in one day | Documents move by courier or online except where the law requires you in person |
| Rejection risk | One mismatch — a name spelled differently from the passport — restarts the chain | Names, dates and stamps are cross-checked before every filing |
| Status tracking | You follow up with each authority | Status updates at each stage, and we handle the fix if a file is returned |
| Advisory role | No one to compare options when your case falls outside the manual | You get advice on the options before work starts, not just execution |
Government fees and timeframes change; ask for an assessment of your own case before you start.
We work as advisers, not only as a document-running agency
Our team has worked on documents, translation and legalisation for more than 15 years, combining notarial attorneys licensed by the Lawyers Council of Thailand with translators the receiving authorities accept. Every case starts with advice on the correct route and only then moves to execution — we do not simply run whatever is handed to us.
Before we start — mapping the document route
We confirm whether your file ends at an Apostille or still needs the embassy, whether a freshly issued copy is required, and which form of translation the receiving authority accepts. This is where most time is saved, because it is where most people choose wrongly and restart.
While preparing — consistency checks
We match the spelling of your name against the passport, check the issue date against the validity window the destination applies, verify stamps and signatures, and confirm the translation matches the original line by line.
While filing — coordination with the authorities
We file in the order each authority expects, follow the queue, and report status as it moves. If an authority asks for more paperwork, you hear about it immediately, together with the options for fixing it.
After delivery — practical guidance
We explain which bodies this set can be filed with, how to store the originals, and how many certified sets to request up front if you expect to use them again, so you do not repeat the whole chain later.
Cases where advice up front changes the outcome
- The name on an older document does not match the current passport because of a name change or a different transliteration.
- Documents have a limited validity window and every item must still be valid on the day of filing.
- The applicant is upcountry or abroad, so the power of attorney and courier plan must be arranged carefully.
- A file was already returned once and the real cause has to be identified before refiling.
If you are unsure which route your case takes, send photos of the documents and name the destination country or authority. We map the sequence and the paperwork first; you then decide whether to run it yourself or hand it over.
What the common mistakes actually cost
Almost every failure in consular department and embassy legalisation happens during preparation, not at the counter, and the real cost is the TIME needed to repeat the chain. Below is what each mistake comes from, how long it typically adds, and how to avoid it.
| Mistake | Why it happens | Time cost | How to prevent it |
|---|---|---|---|
| Booking the wrong service channel or appointment type | Each channel has its own queue and document conditions; the wrong one means booking again. | Typically adds 2–14 working days depending on appointment availability that month. | Confirm the service type and the appointment date in advance and keep at least one spare week. |
| Planning without allowing for public and embassy holidays | Embassies close on both Thai and home-country holidays, so the real calendar is shorter than it looks. | Typically adds 3–9 working days around a long holiday period. | Check the holiday calendar of every body involved before fixing a travel or filing date. |
| Removing staples or separating pages after certification | The certification is attached to the bound set; once separated the set counts as incomplete. | Typically adds 3–7 working days to re-certify the set. | Scan first, then keep the originals in a rigid envelope without detaching anything. |
| Filing an incomplete set — missing an ID copy or a power of attorney | Completeness is checked at the counter; an incomplete file is not accepted at all. | Typically adds 1–5 working days per return trip. | Work from a written checklist and re-check it before leaving, including every copy that needs a signature. |
| The name in the translation does not match the passport spelling | Receiving authorities compare character by character; a single different letter reads as a different person. | Typically adds 3–10 working days, because the translation has to be redone and the whole chain repeated. | Send the passport page on day one and have the translator take the spelling from the passport, never from the Thai document. |
Deep timeline: what can run in parallel
The windows below are approximate and depend on each authority's queue. Stages marked as parallel can start alongside the previous stage — that is where the total calendar time is actually reduced.
- 1. Chain check with the receiving authority1 working day
We confirm whether the file ends at the consular department or must continue to the destination's embassy.
- 2. Originals and translation prepared2–4 working dayscan run in parallel
Reissue anything outside the validity window and produce a translation in the accepted format.
- 3. Filing at the consular department2–5 working days
Timing depends on the service channel chosen and the queue volume that week.
- 4. Filing at the destination embassy3–15 working days
Each embassy sets its own documents, intake days, and collection rounds, so allow the most slack here.
Note: all windows are general estimates, not guarantees. Actual timing depends on how complete your file is and on the queues at the authorities involved.
