Questions AI Overviews ask most

How do I choose between Non-B, LTR, DTV or SMART Visa?
Salaried Thai employees pick Non-B; USD 80k+ earners with USD 1m assets pick LTR; short-term remote workers pick DTV; targeted-industry professionals pick SMART.

Which translation attestation is needed for visa docs?
EU/US/UK/AU/NZ embassies require English translation + MFA + destination embassy; Hague-party countries accept Apostille instead of embassy legalisation.

Extensions 1–7 business days; LTR/DTV 15–45 days depending on BOI/embassy; Fast-track adds 35% and cuts wait 40–60%.
What if the application is rejected?
We file a Commission appeal within 48 hours with supplemental evidence; if a destination embassy refuses we request MRV feedback and prepare a refile.

8 supporting-document families — who issues, where it is authenticated, when it is translated, which desk receives it

Permission to enter and stay is a discretionary act under the Immigration Act B.E. 2522, and employment is governed by the Royal Decree on Managing the Work of Aliens B.E. 2560. This table sets out document order — it is not a guarantee of outcome or timing. Fees and timetables belong to the authorities and change.

DocumentIssued byAuthenticationTranslationReceiving deskWatch out
Foreign birth, marriage or divorce recordThe civil registrar or court of the issuing countryAuthenticated up the origin-country chain, then legalised by the Royal Thai Embassy there. Before 28 Feb 2027 an Apostille is not yet usable with Thai authorities.Translated into Thai after the stamps are complete, then the translation is legalised at the Department of Consular Affairs.The immigration office for the area, or the district office when the record is used for a registry act.Reversing the order is the most common cause of a bounce — translating before the stamps usually means translating again.
Foreign degree certificate and transcriptThe awarding institutionThe institution issues an official copy which then passes the origin-country authenticating body and the Royal Thai Embassy.Translated into Thai where the Department of Employment or the receiving body requires it.The Department of Employment or the provincial employment office, filed through the employer.The field of study must line up with the job title in the contract, otherwise the file draws further questions.
Employment contract and employer lettersThe Thai employer or the overseas parent companyThai company papers are filed as certified copies under company seal; overseas company papers run the origin-country chain.Translated into Thai when the source is not in Thai.The Department of Employment, and immigration at the extension stage.The salary in the contract must match what the visa file and the tax papers state.
Financial evidence: statements, pensions and incomeThe bank or the pension-paying bodyA Thai bank issues an original balance-confirmation letter; a foreign statement runs the origin-country chain.Translated into Thai or English as the receiving body directs.Immigration, or the body assessing eligibility such as the BOI for LTR.Freshness matters more than the amount — an old confirmation letter is often asked for again on the filing day.
Police certificate issued abroadThe national police or criminal-records body of that countryAuthenticated in the origin country, then legalised by the Royal Thai Embassy.Translated into Thai, carrying over every result code and every seal.Whichever body asked for it — commonly the Department of Employment or a sector licensing body.The acceptable age is set by the receiving body, not the issuer — ask before ordering it.
Medical certificate for a work permitA physician licensed to practise in ThailandIssued in Thailand, so no foreign authentication chain applies.Normally issued in Thai already, so no translation is needed.The Department of Employment together with the employer bundle.The form and the conditions it must address are set by the authority and can change — check the current form before the appointment.
TM.30 residence notification and TM.47 90-day reportFiled by the house-master, owner, possessor or manager of the residence; the TM.47 is filed by the foreigner.No legalisation, but proof of the right to the residence is attached — typically the house registration and the house-master's ID.A translation is attached when the lease is in a foreign language.The local immigration office or the Immigration Bureau's online notification system.This duty sits with the person in control of the residence, not the tenant, and failure to notify carries a penalty under the Immigration Act.
Thai documents sent to a foreign missionThe district office, Department of Provincial Administration, or the Thai body that issued the record.Obtain a certified extract from the issuing body, then legalise the translation at the Department of Consular Affairs.Translated into the language the destination mission requires — usually English.The destination embassy or consulate in Bangkok.Some missions require consular legalisation first and some do not want it — check that mission's rule before starting.

8 ways a file comes back — what cures it and where the work restarts

SymptomLikely causeRemedyRestart from
The counter returns the file saying the translation is incompleteSeals, signatures or the endorsement block at the foot of the page were not carried into the translation.Rework the translation so every element on the page appears, then re-certify it.The translation and certification step — no return to the origin country.
Immigration will not accept a foreign document bearing an ApostilleThe Apostille Convention does not enter into force for Thailand until 28 February 2027.Send the document back for Royal Thai Embassy legalisation in the origin country.The Royal Thai Embassy step; the origin-country stamps already obtained remain valid.
The name in the translation does not match the passport pageA different transliteration system, or given name and surname in a different order.Follow the passport spelling as the master form and put other forms in brackets as a translator's note.The translation step, and every document in the bundle must be aligned.
The financial evidence is asked for again on the filing dayThe balance-confirmation letter was issued longer before the filing date than the counter accepts.Obtain a fresh letter from the bank on the same day or as close to filing as possible.The bank step only; the rest of the bundle stands.
Permission to stay lapses because the holder left the countryDeparting without a re-entry permit while the permission was still running.Take a re-entry permit before every departure; once the permission has lapsed a new visa must be sought from outside Thailand.If the permission has lapsed, from a Royal Thai Embassy abroad.
The Department of Employment queries the fit between the job title and the qualificationThe job title in the contract is broader or narrower than the degree and experience support.Align the job description with the qualification and attach certified translations of experience letters.The employer-document step, without affecting stamps already obtained.
The residence notification will not go through because the house-master details do not matchThe person filing is not the one on whom the duty falls, or the house registration and the lease name different people.Have the house-master, owner or manager file, attaching proof of the right to the residence.The notification step; the existing visa is unaffected.
A destination mission will not accept Thai documents that already carry consular legalisationThat mission requires the certified extract and translation directly, without the Department of Consular Affairs step.Obtain a fresh certified extract from the issuing body and file in the form that mission prescribes.The Thai issuing body.

16 direct answers

How must a foreign document be authenticated before a Thai immigration filing?

Run the origin country's own chain first, then have the Royal Thai Embassy there legalise it, then translate into Thai and legalise the translation at the Department of Consular Affairs.

Can an Apostille replace consular legalisation in Thailand yet?

Not yet. The Apostille Convention enters into force for Thailand on 28 February 2027; before that date no Thai authority issues or accepts an Apostille in place of the legalisation chain.

Who has the duty to notify where a foreigner is staying?

The house-master, owner, possessor or manager of the residence must notify the immigration office under the Immigration Act B.E. 2522 — not the foreign tenant.

Are the 90-day report and the residence notification the same thing?

No. The residence notification is the duty of whoever controls the residence when a foreigner stays there; the 90-day report is the foreigner's own duty to report a current address after ninety continuous days.

What must be done before leaving Thailand while holding an extension of stay?

Take a re-entry permit before departing. Without it the permission to stay ends on leaving the Kingdom and a new visa must be obtained from abroad.

Must a foreign degree always be translated into Thai for a work permit?

It depends on the receiving office. The Department of Employment generally asks for a Thai translation when the original is not in Thai — confirm with the provincial employment office before ordering.

How long is a foreign police certificate valid for?

The receiving body sets the acceptable age, not the issuer. Ask the destination body before ordering, since some files require a certificate issued within only a few months.

Translate first or legalise first?

For a foreign document used in Thailand, collect every foreign stamp first, then translate into Thai — the translation must cover every seal that appears on the document.

How does the digital work permit differ from the old booklet?

It records the permission in the Department of Employment's system instead of issuing a booklet. The statutory duties — notifying a change of employer or position — remain the same under the Royal Decree on Managing the Work of Aliens.

Does changing employer mean starting the whole process again?

A change of employer must be notified and processed as the Royal Decree prescribes, and the visa and work permit must stay aligned — sequence it with the new employer before the old engagement ends.

Where are visa applications to Thai missions lodged?

Royal Thai Embassies and Consulates-General take applications through the Ministry of Foreign Affairs e-Visa system; the visa types and document lists for each post are shown there.

How does the One Stop Service channel differ from an ordinary immigration office?

It brings the immigration and work-permit counters together for applicants who qualify through the investment-promotion channels; eligibility and documents are set by the body that owns the channel.

What has to happen to overseas company documents used in Thailand?

They run the authentication chain of the country of incorporation, are legalised by the Royal Thai Embassy, then translated into Thai with the translation certified as the receiving body requires.

Can a copy stand in for the original?

Counters generally inspect the original and keep a signed certified copy, so bring the original every time even when the system allows an online pre-submission.

If refused, can the application be refiled immediately?

Permission is a discretionary act under the law. A refiling is possible once the stated ground has been cured — ask for the reason in writing and fix that specific point before going back.

Do Thai documents for a foreign mission need consular legalisation first?

It depends on the mission: some require the Department of Consular Affairs step first, others take a certified extract with a translation directly. Check that mission's published requirement before starting.

8 origin-country groups — authentication order, translation and name risk

Permission to enter and stay is a discretionary act under the Immigration Act B.E. 2522. This table explains document order by country of issue — it is not a guarantee of outcome or timing. Fees and timetables belong to the authorities and change.

OriginTypical issuerOrigin chainTranslationName risk
United Kingdom, Ireland and Commonwealth statesThe central or local civil registryThe national legalisation office authenticates first, then the Royal Thai Embassy there legalises.Translated into Thai after the stamps are complete, with the translation legalised at the Department of Consular Affairs where the receiving body requires it.Middle names and titles must follow the passport page exactly.
United StatesThe state or county vital-records officeAuthenticated at state level first, then by the Royal Thai Embassy or Consulate-General whose consular district covers that state.Translated into Thai after the stamps, and the state seal must appear in the translation.Some records use an initial for the middle name; explain it in a translator's note.
European Union and states using multilingual formsThe municipal registry or central civil registerA multilingual form aids reading, but the origin-country authentication and the Royal Thai Embassy step still apply.Most Thai bodies still ask for a Thai translation even when the original carries an English column.Diacritics must be preserved and transliterated into Thai consistently.
China, Japan, Korea, TaiwanThe household register or a state notarial officeUse the state-issued or state-notarised version, then the origin-country authenticating body and the Royal Thai Embassy.Translate into Thai while keeping the original characters in brackets so the record can be traced back.The register name may differ from the romanised passport name; a linking note is required.
South AsiaThe local registrar, a court, or a state registration bodyCleared by the origin-country ministry of foreign affairs first, then the Royal Thai Embassy.Non-English records must be translated from the source document, not from a summary sheet.Patronymic naming instead of a surname is common and must be explained to the counter.
Middle East and North AfricaThe ministry of interior or a Sharia court depending on the recordAuthenticated up the chain that country prescribes, then legalised by the Royal Thai Embassy.A direct Arabic-to-Thai translation carries less drift than a translation through a third language.Long multi-element names must be matched to the passport page element by element.
Sub-Saharan Africa and Latin AmericaThe national registry or a public notaryWhere no Royal Thai Embassy is resident, file through the Thai mission holding concurrent accreditation for that country.Translate into Thai from the Portuguese, Spanish, French or other official language of the original.Double-surname systems must keep their original order and be explained.
States whose registry is not functioning, or where records were destroyedThat country's embassy in Thailand, or a relevant international bodyA letter from the applicant's own embassy in Thailand can stand as substitute evidence, then legalised at the Department of Consular Affairs where the receiving body accepts it.The translation should state plainly that it is a substitute attestation, not an original register extract.Acceptance of substitute evidence is at the discretion of each receiving body.

8 family and dependant situations

SituationRelationship proofThai-side stepWork noteWatch out
Foreigner married to a Thai nationalThe Thai marriage register, or a foreign marriage recorded as a family-status entry.Register, or record the family status, at the khet or amphoe office.Marriage confers no right to work; work requires authorisation under the alien-work legislation.Names and dates of birth must agree across every document or the registrar will send it back first.
Spouse of a work-permit holderA marriage record with the chain complete and a Thai translation.File the dependant bundle alongside the principal's file at the area immigration office.Dependant status does not permit work; a change of status and a separate work permit are needed.The dependant's permission tracks the principal's; when the principal's ends, the dependant's ends with it.
Children of a foreigner working in ThailandA fully authenticated birth record with a Thai translation, plus the parents' passport pages.Attach a school enrolment letter where the child is of school age.Not a work matter, but moving on to higher education may require a different visa class.A birth record naming the parents differently from their passports draws further questions.
A child born in Thailand to foreign parentsThe Thai birth certificate issued by the khet or amphoe office.Register the birth under the civil-registration law, then obtain a passport from the parents' embassy.Not a work matter.A Thai birth certificate for overseas use needs an English translation legalised at the Department of Consular Affairs before the destination mission.
A foreign student and an accompanying parentThe institution's acceptance letter and a birth record showing the relationship.The institution issues a letter to immigration at each extension round.Study confers no right to work; a paid internship requires work authorisation.Discontinuing the course affects both the student's and the accompanying parent's position.
An adoption completed abroadThe court order or adoption certificate, fully authenticated and translated into Thai.Record it at the khet or amphoe office where the receiving body wants a Thai-side record.Not a work matter.An adoption involving a Thai child follows a separate statutory process with its own responsible agency.
Parental power and travel with one parent onlyA custody order, or the other parent's consent signed before a certifying officer.Translate into Thai and certify the translation when it is used with a Thai authority.Not a work matter.Airlines and the destination border may ask for the consent letter even when the Thai side does not.
An elderly parent in the applicant's careThe applicant's birth record naming the parent, or a family register linking the relationship.File with the support and accommodation evidence the area immigration office specifies.Not a work matter.A parent who meets the age threshold may instead file on their own retirement footing, which is often a lighter bundle.

Is an Apostille usable in Thailand yet?

Not yet. The Apostille Convention enters into force for Thailand on 28 February 2027. Until then the origin-country chain plus Royal Thai Embassy legalisation still applies.

What if there is no Royal Thai Embassy in the origin country?

File through the Royal Thai Embassy holding concurrent accreditation for that country. Check the consular district on the Ministry of Foreign Affairs website before sending anything.

Does a European multilingual form still need a Thai translation?

Most Thai bodies still ask for a Thai translation even when the form carries an English column. Ask the receiving body first so the translation is not done twice.

The Chinese household register name differs from the passport — how is that fixed?

Use the passport spelling as the master form in the translation, then place the original characters and any other transliteration in brackets as a translator's note.

No birth certificate because the origin registry is not functioning — what substitutes?

A letter from the applicant's own embassy in Thailand can often stand in, but acceptance is at the discretion of each receiving body.

Does marrying a Thai national allow the foreigner to work?

No. Marriage confers no right to work. Working in Thailand requires authorisation under the alien-work legislation, separate from permission to stay.

May a dependant of a work-permit holder work?

Dependant status does not permit work. An employer, the required change of status, and the dependant's own work permit must be in place before any work starts.

Is a marriage registered abroad usable in Thailand as it stands?

It must clear the origin-country chain and the Royal Thai Embassy, be translated into Thai, then be recorded as a family-status entry at the khet or amphoe office where a Thai-side record is required.

A child born in Thailand to foreign parents — what comes first?

Register the birth at the khet or amphoe office to obtain the Thai birth certificate, then apply for a passport at the parents' embassy, before dealing with permission to stay.

Is a consent letter needed when a child travels with one parent?

The Thai side does not always ask, but airlines and the destination border often do. Prepare it with a translation in advance to reduce the risk of a boarding refusal.

Must South Asian documents clear the origin foreign ministry first?

Generally yes: the Royal Thai Embassy legalises on top of the origin foreign-ministry stamp. Skipping that step is a common cause of rejection.

Can an Arabic record be translated via English first?

It is possible but adds drift, especially in personal names and dates. A direct source-to-Thai translation is easier to trace back.

Must a dependant also make the 90-day report?

The 90-day address report is a duty of each foreigner staying continuously in the Kingdom, not only of the principal file-holder.

How should an elderly parent's stay be arranged?

If the parent meets the retirement age threshold, filing on their own footing is usually a lighter bundle than filing as a dependant. Compare both routes before deciding.

Is a foreign custody order effective in Thailand immediately?

It must be authenticated and translated into Thai before use with a Thai authority, and the effect of a foreign order in Thailand is decided case by case under Thai law.

Does the dependant's permission end with the principal's?

As a rule it tracks the principal: when the principal's permission ends or is cancelled, the dependant's status ends with it, so plan renewals together.

8 lifecycle events — who files, and the effect on stay and on work

Extensions of stay and changes of the reason for stay are discretionary acts under the Immigration Act B.E. 2522. This table explains what each event does to a file — it is not a guarantee of outcome or timing. Fees and timetables belong to the authorities and change. Our service pricing is quoted by our staff by phone, LINE or email.

EventWho filesEffect on stayEffect on workWatch out
Applying to extend the period of stay before the current permission endsThe foreigner files in person with the immigration officer for the area of residence.An extension is a discretionary grant under s.35 of the Immigration Act B.E. 2522 — it is not the issue of a new visa.Permission to stay grants no right to work; that lies in the work authorisation under the alien-work legislation.File before the permitted date ends — an incomplete bundle is sent back for correction and the clock does not stop.
Changing the reason for stay while inside the KingdomThe foreigner applies to change the type of visa, with evidence supporting the new reason.If granted, a new visa class and a fresh permitted period are issued — this is not a continuation of the old one.A visa class consistent with employment is normally needed before a work permit can be applied for.In practice enough permitted days must remain on the day of filing; too few and the request is refused, leaving a trip abroad as the only route.
Reporting after staying over 90 days in the KingdomEach foreigner carries the duty under s.37(5); it may be lodged in person, by post, online or by an authorised person through whichever channel the office offers.Reporting is not an extension — it adds no days to the permitted stay.It does not touch the work permit directly, but the receipt is commonly asked for at work-related renewal.A departure restarts the 90-day count from the day of return, which is where frequent travellers most often miscalculate.
Notifying that a foreigner has taken residence in a dwellingThe housemaster, owner or possessor of the dwelling, or the hotel manager, carries the duty under s.38 — not the foreigner.It does not change the permitted dates, but it is the address evidence the office uses to test the file.Unrelated to the work permit.Absentee landlords frequently do not know of this duty, so tenants should settle who files it in the lease from the outset.
Travelling abroad during a granted extensionThe foreigner obtains re-entry permission before departing.The permission to stay ends on departure unless valid re-entry permission is held.If the permitted stay lapses, the footing of the work permit is affected with it.Re-entry permission adds no days; it only preserves the existing permitted date.
Employment ends or the employer changesBoth employer and alien have notification duties under the alien-work legislation, and the stay file is separate from the work-permit file.Where the reason for stay was that employment and it ends, the original footing falls away — a new footing or departure is required.A work permit is tied to the named employer and workplace; work outside that scope is not covered by it.Do not wait for cancellation before planning; prepare the new footing as soon as the end date is known.
Staying beyond the permitted dateThe foreigner bears the liability and should approach the authorities before being found.Staying in the Kingdom without permission is an offence under s.81 of the Immigration Act B.E. 2522.Working during an overstay adds a further layer of liability under the alien-work legislation.Consequences include a period of prohibition on entry set by law and regulation, and the record follows later applications; the amounts and periods belong to the authorities.
Moving to a new address inside ThailandThe new housemaster or possessor notifies the residence, and the foreigner notifies the change of address through the channel the office specifies.The dates are unaffected, but the address on record must match the real address used at the next filing.If the workplace moves too, the work permit entry must be amended separately.Mismatched addresses across the 90-day receipt, the lease and the previous file are the most frequent cause of rework.

16 direct answers

My visa has expired but the permitted-stay stamp has not. Can I stay?

A visa governs entry; how long you may remain is the date in the permission-to-stay stamp. While that date has not passed the stay is lawful, but leaving without re-entry permission ends it.

Does the 90-day report give me more time in Thailand?

No. It is only an address notification under s.37(5) and adds no days to your permitted stay.

If I leave Thailand, does the 90-day count restart?

Yes. The count restarts from the day you re-enter, because the duty attaches to continuous stay in the Kingdom.

Is TM.30 my duty or my landlord's?

Section 38 places it on the housemaster, owner or possessor of the dwelling, or the hotel manager — not on the foreigner. The practical fallout still lands on the tenant at the counter, so settle it in the lease.

Can I change from a tourist visa to a work visa inside Thailand?

An in-country change of visa class is possible in some cases and is discretionary. In practice enough permitted days must remain on the filing day and the evidence for the new reason must be complete; otherwise the route is a Royal Thai Embassy application abroad.

How is a re-entry permit different from a multiple-entry visa?

A multiple-entry visa is issued by an embassy before you arrive. Re-entry permission is issued inside Thailand to stop an existing permitted period from lapsing when you depart.

If I resign, does my permission to stay end immediately?

The footing for your stay was employment with that employer, so it falls away when the job ends. The practical effect depends on cancellation of the work permit and on the officer's assessment, so prepare a new footing before the last working day.

I have overstayed. What should I do first?

Staying without permission is an offence under s.81. We always advise approaching the authorities yourself rather than being found. Consequences include a statutory period of prohibition on entry, which is the authorities' to apply.

How must a foreign document used in a renewal file be authenticated?

Authentication in the country of origin, then legalisation by the Royal Thai Embassy holding that consular district, then Thai translation, then legalisation of the translation by the Department of Consular Affairs where the receiving body requires it. No Apostille exists until the Convention enters into force for Thailand on 28 February 2027.

How far in advance can I file an extension?

Each office sets its own advance-filing window and these change, so ask the office covering your area before you travel there. What is certain is that filing belongs before the permitted date ends, not after.

Can an authorised representative file on my behalf?

Some matters, such as the 90-day address report, allow a representative or postal filing under the office's rules, but an extension application generally requires the applicant to attend and be photographed at the counter.

How long should I keep receipts and notification slips?

Keep 90-day receipts, residence-notification receipts, copies of every application and all stamped passport pages for the whole period of residence — the next round routinely tests continuity backwards.

How do Immigration and the Department of Employment differ?

Immigration owns entry, permission to stay and address reporting; the Department of Employment owns work authorisation. They are separate files with separate dates.

What must be done after moving house?

The new housemaster or possessor files the s.38 residence notification, and every document must then agree: the 90-day receipt, the lease and the next application.

May I start work as soon as my extension is granted?

No. Stay and work are separate. Work requires a valid work permit matching the named employer and workplace.

What causes files to be sent back most often?

In the files we handle: addresses that disagree across documents, name spellings that differ from the passport, foreign documents that have not completed the authentication chain, and Thai translations left unlegalised where the receiving body requires it.

8 long-stay routes — who decides, on what legal basis, what it gives and what it does not

Permission to stay, residence and nationality are discretionary acts of the Thai authorities. This page states the legal basis and the deciding body only — it promises no outcome and quotes no fee.

RouteAdministered byLegal basisWhat it givesWhat it does not give
Ordinary annual extension of stay (TM.7)The local immigration officeImmigration Act B.E. 2522 s.35 — a discretionary grantThe right to remain until the date stamped, renewable period by periodIt is not residence, it does not authorise work, and it does not ripen into a permanent status by itself

7 classes of foreign document — the certification chain before a Thai authority accepts them

DocumentIssued byCertification chainWhere files trip up
Police clearance / criminal record certificate from abroadThe police or criminal-records authority of that countryAuthenticated in the country of origin → legalised by the Royal Thai Embassy there → translated into Thai → the translation legalised by the Department of Consular Affairs where the receiving body requires itThe receiving body usually sets its own recency rule, so ask it before starting the chain
Marriage certificate registered abroadThe registrar of the country of registrationAuthenticated at origin → Royal Thai Embassy legalisation → Thai translation → Consular Affairs legalisation of the translation → recorded in the family-status register at the district office where neededRecording family status is not the same as registering a marriage in Thailand, and a nationality file usually wants consistent Thai civil-registration paper
Income, pension or financial standing letter from abroadAn employer, pension fund or financial institution abroadSigned by the authorised officer and the signature certified by a Notary Public → Royal Thai Embassy legalisation → Thai translation → Consular Affairs legalisation of the translation where requiredSignature certification attests only who signed; it does not certify that the figures are true
Degrees and professional certificates from abroadThe awarding institution or professional body abroadObtain an institution-certified copy, or have a Notary Public certify the copy as a true copy → Royal Thai Embassy legalisation → Thai translation → Consular Affairs legalisationA BOI file and a Department of Employment file may ask for different sets, so keep spare originals of the chain
Power of attorney to act in ThailandThe grantor, signing before a certifying officerSigned before a Notary Public abroad, or before a Notarial Services Attorney in Thailand → further legalised by the embassy or the Department of Consular Affairs as the receiving body requiresMany Thai bodies prescribe their own power-of-attorney form; a self-drafted one can be refused
Thai civil-registration documents that must line upThe district or khet registration officeObtain certified extracts of the house registration, marriage registration and related entries, then check that names, dates of birth and spellings match the passport across every documentName-spelling mismatches between Thai paper and the passport are the most common reason a file is sent back

12 self-contained answers on long stay, residence and nationality

After enough yearly extensions, do I become a permanent resident automatically?
No. An annual extension is a period-by-period permission under s.35. Permanent residence is a separate application under s.40 and falls within a quota published in the Government Gazette.
What is the permanent-residence quota for each nationality?
Section 40 requires the Minister, with Cabinet approval, to publish the annual number in the Government Gazette, not exceeding one hundred persons per nationality per year and not exceeding fifty persons for people without nationality.
What is the difference between permanent residence and Thai nationality?
Permanent residence lets you remain without annual filings but you are still an alien, holding a residence certificate and an alien registration book. Thai nationality is a status under the Nationality Act B.E. 2508, effective on the oath of allegiance and Gazette publication under s.12.
How many years in Thailand does naturalisation require?
Section 10 of the Nationality Act B.E. 2508 requires domicile in the Kingdom for a consecutive period of not less than five years up to the date of application, alongside the other conditions — sui juris, good behaviour, a regular occupation and knowledge of the Thai language as prescribed. Section 11 allows relaxations in defined cases.
Does marrying a Thai national give Thai nationality straight away?
No. Marriage confers nothing automatically. Section 9 allows an alien woman who has married a Thai national to apply for Thai nationality — it is an application that must be considered and fully documented.
Does Thailand Privilege or LTR count as domicile for a nationality file?
Both are stay channels, not a grant of residence under immigration law. Whether an applicant has the consecutive domicile s.10 speaks of is a factual assessment made by the officers from the residence and tax evidence in the file, so no programme should be assumed to deliver it automatically.
Once I hold permanent residence, do I still file the 90-day report?
The s.37(5) report attaches to a foreigner permitted to stay temporarily. A resident has their own set of duties tied to the residence certificate and the alien registration book — renewing the book and endorsing the certificate before travelling — and the detail should be confirmed with the issuing office each time.
Does permanent residence authorise work by itself?
No. Work authorisation sits in a different statute — the Royal Decree on Managing the Work of Aliens B.E. 2560 as amended. Residence does not replace the work authorisation that decree requires.
Can I lose permanent residence by travelling?
A resident who leaves and wants to return with the same status must have the residence certificate endorsed as immigration law requires before travelling; otherwise the status can lapse. The Act also sets out grounds for revocation.
My foreign document already has an Apostille — can I file it as is?
Not yet. The Apostille Convention enters into force for Thailand on 28 February 2027 per the HCCH status table. Before that date no Thai authority issues or accepts an Apostille, so the ordinary chain through the Royal Thai Embassy and the Department of Consular Affairs still applies.
I had a gap in my extensions — does that hurt a long-stay file?
Continuity of stay and of paperwork is a fact the officers weigh, so a gap is something to explain with evidence rather than ignore. The effect turns on the facts and on discretion, which is why we never promise an outcome in advance.
What do you charge for a residence or nationality file?
It depends on the number of documents, the source language and the chain the receiving body requires, so no figure is stated on this page. Please ask our staff by phone, LINE or email with your document list to hand.

We serve individuals, expatriates, cross-border couples, students, corporates, multinationals, and government agencies requiring documents with legal effect both inside Thailand and abroad.

All notarial acts follow the Lawyer Act B.E. 2528 (1985) Section 27 read with the Lawyers Council Regulation on Notarial Services Attorneys B.E. 2546 (2003), the sole legal basis authorizing Thai attorneys to certify documents comparable to a foreign Notary Public. Every attorney on our team has completed the accredited training and examination administered by the Lawyers Council and holds a verifiable registration number searchable on the Lawyers Council public registry.

By choosing a firm that houses Notarial Services Attorneys in-house, clients consolidate a multi-stage legalization chain under one accountable roof: attorney notarization, followed by Ministry of Foreign Affairs (MFA) legalization at the Department of Consular Affairs, followed by embassy or consular legalization for the destination country. Since 21 November 2024 the Kingdom of Thailand has become a party to the Hague Apostille Convention (Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents). Documents apostilled in Thailand are now accepted in more than 125 member states without embassy re-legalization, materially reducing turnaround time and cost.

General Information and Firm Framework — Deep Context

The firm operates under an ISO 9001:2015 quality-management framework and enforces data protection consistent with the Personal Data Protection Act B.E. 2562 (2019). All client documents are stored with AES-256 encryption at rest and in transit and are retained for ten years in accordance with lawyer-record obligations under the Lawyer Act.

Our team combines Notarial Services Attorneys, NAATI-certified translators, and legal specialists in intellectual property, taxation, cross-border family law, corporate law, and immigration law, together with a support team dedicated to documentation, translation, and government-agency liaison.

Fees are transparent and disclosed both on the website and in the pre-engagement quote, separating professional fees, government fees, travel disbursements (if any), and other line items. The firm issues VAT invoices and official receipts and accepts payment by bank transfer, credit card, PromptPay, and cash.

Trust Standards — PDPA, SLA, Quality Assurance

On data protection, the firm strictly follows the Personal Data Protection Act B.E. 2562 (2019), Sections 24, 26, and 27 — collecting, using, and disclosing personal data only to the extent necessary for the engagement, disclosing purposes, and obtaining consent from data subjects in advance. Clients retain the right to inspect, obtain a copy, rectify, erase, or withdraw consent at any time through the firm's Data Protection Officer (DPO). For clients in the European Union, processing follows GDPR Article 6 (lawful basis) and Article 46 (Standard Contractual Clauses).

Our Service Level Agreement targets an inquiry response within one hour during business hours (09:00–18:00, Monday to Saturday), attorney appointments within twenty-four hours, standard notarization within one business day (or two to three hours on express service), certified translation within three to five business days per ten A4 pages, MFA legalization within two business days on standard service (one business day express), and embassy legalization typically within three to fifteen business days depending on the mission's own policy.

Every deliverable passes a three-tier quality-assurance chain: (1) the responsible attorney or translator, (2) a Senior Attorney or department head reviewing substance and formatting, (3) a Quality Control desk performing the final pre-delivery check. Any firm-side error is remedied at no additional cost, and if a document is rejected by a government authority due to a firm-side error, we cover the entire re-filing fee.
