Turnkey work-authorization package
End-to-end legal support for foreign professionals working in Thailand and for the Thai companies that hire them. We handle Non-Immigrant B visa (from Thai embassy abroad or in-country conversion), Work Permit (Baan-Suan-Bplai / DOE), 90-day reporting, TM.30 property registration, re-entry permits, one-year extensions, and BOI/IEAT fast-tracks — under one fixed-fee package with monthly compliance reminders.

Working legally in Thailand as a foreign national requires two separate but interlocking authorizations — a Non-Immigrant B visa issued by the Immigration Bureau and a Work Permit issued by the Department of Employment. Missing either one exposes the employee and the employer to fines up to THB 100,000, deportation, and a 5-year employment ban. The regulations changed materially in 2023–2025 (digital Work Permit rollout, mandatory Social Security within 30 days, TM.30 e-filing, tightened capital-to-headcount ratios), and most foreign employees discover the compliance calendar only when a document has already lapsed.
Our firm supports both sides of the transaction — the Thai company (2 million baht paid-up capital per foreign employee, 4 Thai employees per foreign work permit for regular LTD, or 1:1 for BOI-promoted companies) and the foreign professional (educational credentials, criminal-background clearance from home country, health insurance meeting the THB 400,000 minimum for long-stay visa). The package covers 12 months of compliance from the Non-B issuance date, including monthly 90-day reminders, annual extension filings, and immediate response to any change of address, job title, or salary that triggers re-registration.

PDPA and data protection
How is Non-B different from Non-O or SMART Visa?
Non-B is for employment with a Thai company and always paired with a Work Permit. Non-O is for family (Thai spouse, Thai child, retirement), does not authorize work. SMART Visa is for high-skilled talents in 10 target industries — 4-year stay, no Work Permit required, but you must be endorsed by BOI/DEPA/NIA.
Can I convert from tourist visa (TR) to Non-B in-country?
Yes but eligibility is limited — only certain nationalities, only at Chaeng Wattana (Bangkok Immigration Division 1), and only if you have not previously overstayed. Processing 15 working days. Better to obtain Non-B from a Thai embassy abroad before entering.
What is the minimum company capital and Thai employee ratio?
Regular Thai LTD: THB 2 million paid-up per foreign Work Permit, 4 Thai employees per 1 foreigner. BOI-promoted companies: no minimum capital or ratio. Rep-Office: 2 million paid-up over 3 years, 1:1 Thai ratio.
What is the minimum salary for the foreign employee?
Depends on nationality band: USA/Canada/EU/AU/JP quote on request; Korea/Singapore/Taiwan quote on request; South Asia/Africa THB 25,000. Immigration cross-checks against payslip and Social Security base — undeclared salary triggers Work Permit refusal.
What happens if my Work Permit expires or I change jobs?
Work Permit is tied to one employer. Change of job requires filing a new WP.3 with the new company within 15 days; Non-B extension of stay also requires re-registration. Overstay on either side triggers fines and possible 1-year ban.
Do I need to file TM.30 every time I travel domestically?
TM.30 is a landlord's obligation to report the foreign guest after document review of arrival at any address that is not the registered residence. If you go on a weekend trip and return, landlord must re-file. If you check in to a hotel, the hotel files. Missing TM.30 fines THB 800–2,000.
Is health insurance mandatory?
Not for Non-B but strongly recommended (Social Security covers only THB 30,000/incident). For O-A retirement visa and 1-year extension based on retirement, THB 400,000 minimum coverage is mandatory.
How is client data protected under PDPA?
Digital files AES-256 encrypted on Thai servers; originals in a locked safe. 7-year retention per Lawyers Council and Revenue Department. Disclosure only to DOE, Immigration, Social Security, Revenue as strictly required.

Short answer: Visa and immigration outcomes turn on complete, internally consistent documents covering identity, accommodation, finances and the reason for staying. Requirements vary by visa category and receiving office, so confirm the current checklist with the authority before every filing.

Document and legalization advisers with 15+ years of practice
Before we start, we read your actual documents and confirm the legalization route matches what the receiving authority asks for. During the work we report progress, and after delivery we still answer questions about how to submit the file.
We prepare documents to the requirements of the receiving authority. Any approval decision remains at that authority's discretion.
Send your documents on LINE for a preliminary review, a recommended legalization route and a written quote.
General guidance, not a case-specific determination. Requirements change with agency notices — confirm with the receiving authority before you act.

Questions we answer most often for foreign residents: residence notification, 90-day reporting, converting to a Thai driving licence, and preparing paperwork banks accept. We separate what the law requires from what each individual office decides.
TM.30 is the notification that a foreign national is staying at an address, required under the Immigration Act B.E. 2522. The duty sits with the house master, owner or possessor of the premises, not with the foreigner personally. Hotels file automatically; for a rented condo or house the landlord files. Local immigration offices interpret the details differently, so confirm with the office covering your address.
They are separate obligations. Ninety-day reporting is the foreign national's own duty to notify immigration of their current address at set intervals during a continuous stay. TM.30 is the property side's notification that someone is staying there. Filing a 90-day report is not a visa extension and does not lengthen your permission to stay by a single day.
The law provides a fine for the person under the duty to notify. The amount applied and how it is settled is at the officer's discretion and varies by office, so we do not print a fixed figure here. In practice the more common consequence is being asked to file the missing notification first before an extension or 90-day report can be processed.
Yes, where the type of stay is one the Department of Land Transport accepts. You will generally need your passport, evidence of your address in Thailand, and a medical certificate in the accepted form. Address evidence is usually a residence certificate from your embassy or one issued by immigration. Document age rules and extra steps differ between transport offices, so call the office before travelling to file.
An IDP must be issued by the country that issued your underlying licence and is only valid alongside that original licence. Its validity is what the booklet and the issuing convention state. Long-stay residents are usually better off converting to a Thai licence, because insurers and officers verify it more easily. Check current conditions with the Department of Land Transport before deciding.
Today the standard route is certification in the issuing country, then legalisation through the Thai embassy there or that country's embassy in Thailand, then a Thai translation legalised at the Department of Consular Affairs. Thailand's Apostille Convention enters into force on 28 February 2027; until that date the embassy route still applies.
Acceptance is each bank's and each branch's policy under know-your-customer and anti-money-laundering rules. Commonly requested items are the passport, evidence of permission to stay, and proof of a Thai address; some branches also ask for an employer or embassy letter. We prepare and translate the supporting documents, but the decision to open the account rests with the bank.
Three things: the minimum cover the specific visa type requires, whether the policy names you exactly as your passport does, and whether the cover period spans the whole stay you are applying for. Some offices also want an English confirmation letter from the insurer. Always verify the requirement with the embassy or immigration office you will file with before you buy.
Yes. We maintain one schedule covering passport, visa, work permit, 90-day cycle, insurance and driving licence, and send staged reminders before each date. This addresses the most common failure we see: one expired item blocking an otherwise complete filing. Ask our staff about the monitoring service by phone, LINE or email.
The statutes set a broad framework and each office issues its own internal practice on top of it — number of copies, the format of the map to your residence, how recent a medical certificate must be. That is why we confirm the list with the office that will actually receive the filing, rather than relying on a generic checklist found online.

No. It is intended for short-term business travel by bona fide business people — meetings, negotiations, conferences and similar. It does not confer the right to work or reside, and it does not replace a work permit or a long-stay visa in any economy. Using it for the wrong purpose risks refusal at the border and later applications.
Usually proof that you are a genuine business person: company registration and affidavit showing your position, a letter from the company describing your travel need, evidence of trade or investment with APEC economies, and a clean record declaration. Foreign-issued items generally need certified translation, and Thai corporate records may need consular legalisation depending on where they are read.
The card is granted on the basis of your role in a specific business, so a change of employer normally requires notification and, in most cases, a fresh application rather than a simple amendment. Continuing to travel on a card that no longer reflects your position is a compliance risk. Confirm the procedure with the issuing authority before your next trip.
Treat pre-clearance as the pacing item, not the printing of the card. Because each economy screens separately and returns its decision on its own schedule, the useful economy list can keep filling in for months after you apply. Applying several months before a travel season is the practical approach; we cannot promise a date for any single economy.
Match the machine-readable passport spelling exactly, in every translation, affidavit and application form. Thai civil records often transliterate a name differently from the passport; when that happens, the safer fix is a translator's note tying both spellings to the same person, rather than silently changing one document to match another.
Often yes for supporting purposes: we compare the copy with the original passport in front of us and certify that it is a true copy. Whether the receiving authority accepts a copy in place of the original is their rule, not ours — banks and land offices in particular still ask to sight originals. Check before relying on copies alone.
In our experience the recurring causes are a name spelled inconsistently across documents, a missing step in the legalisation chain, a translation attached in the wrong order, an expired supporting document such as a company affidavit or bank letter, and a signature certified for a person who was not authorised to sign. Send us the rejection notice and we work backwards from it.
Translation, document review and consular submission can generally proceed from scanned files plus an authorisation. Signature authentication cannot: you must sign in front of the certifying attorney with your original passport. Clients abroad usually have signature work done locally and send the authenticated document here for the Thai leg of the chain.
As a planning range, translation and internal checking usually take a few working days, and consular legalisation adds several more depending on whether the normal or expedited channel is used. Embassy queues and any overseas leg sit outside our control and are frequently the longest part. We give a case-specific estimate once we have seen the actual documents.
Send scans or clear photographs of every page, tell us the destination country, the authority that will read the document and the deadline, and our staff will confirm the scope and fee by phone, LINE @Thainotary or email. Quoting from a document description alone is unreliable, because the certification chain depends on what is actually printed on the page.
The Department of Employment under the Ministry of Labour, acting under the Royal Decree on the Management of Foreign Workers' Employment B.E. 2560 as amended in 2561. Immigration handles your visa and stay; the Department of Employment handles the right to work. They are separate approvals with separate documents, and an issue with one does not automatically fix the other.
No. Working before the permit is issued exposes both you and the employer to penalties under the Royal Decree. Employers sometimes describe an unpaid orientation period as safe; treat any duties that resemble work as work. Wait for the permit book or digital permit to issue, and keep the employment start date in your contract consistent with it.
A permit is tied to the employer and the work described in it. Taking on separate paid clients, or working at a location not covered by the permit, generally needs a change or an additional permit. The safe route is to ask the Department of Employment through your employer's HR before the second engagement starts, not after an inspection.
The work permit ends with the employment, and the extension of stay that was granted on the basis of that employment is usually cut short soon after. Timelines are decided by Immigration case by case, so do not assume you keep the full remaining validity. Plan the handover date, the permit cancellation and your next entry category together.
Short answer: The usual triggers are funds not held for the required period, foreign documents without legalisation and Thai translation, an address that does not match the residence notification, and filing too close to expiry to fix anything. Planning the timeline is the strongest prevention.
We assess eligibility, sequence fund seasoning and foreign-document certification, and file only when the bundle is complete — speak to our advisers before you start.
