Why Choose NYC Visa & Translation

How to choose the right Thailand Work Permit · American (USA) × BOI Work Permit (Investment-Promoted Company) provider in Thailand

Choosing the right Thailand Work Permit · American (USA) × BOI Work Permit (Investment-Promoted Company) provider directly impacts the success and turnaround of your case. NYC Visa & Translation has worked with BOI One-Stop Service Center (OSSC) + Department of Employment since 2010, handling a broad real-world caseload across government documents, certified translations, and documents intended for use abroad. Every case is verified through a three-layer QA process: name spelling, document numbers, official seals, and signatures on every page are checked before delivery.

Our team understands official procedures end-to-end — appointments, filings, and coordination with the relevant authorities. You do not have to travel back and forth or risk rejection. Our Thailand Work Permit · American (USA) × BOI Work Permit (Investment-Promoted Company) service supports Express handling that completes in half the standard turnaround.

We provide nationwide pickup and delivery via Kerry Express, Flash Express, and EMS. Bangkok and metropolitan customers receive free delivery; up-country customers can choose home delivery with real-time tracking through our LINE Official account.

Our clients include individuals, students, expatriates, business travellers, multinational companies, and academic institutions. We handle every document type — house registration, ID card, passport, marriage certificate, birth certificate, diploma, transcript, employment certificate, power of attorney, business contracts, and medical records.

Our Thailand Work Permit · American (USA) × BOI Work Permit (Investment-Promoted Company) workflow runs in six clear stages: (1) receive originals and copies, (2) QA-audit the source for issues that would cause rejection, (3) translate through a native-speaker linguist, (4) certify with the authority required by the receiving country, (5) file and follow up at each government touchpoint, and (6) deliver plus retain a signed PDF you can re-download for five years. A single Case Officer owns your file end-to-end, eliminating hand-off errors that plague larger firms.

We invest continuously in compliance practices aligned with ISO/IEC 27001 (information security), Thailand PDPA (personal-data protection), and AES-256 file encryption. Every upload runs over TLS 1.3 only. Enterprise and law-firm clients can request an NDA before intake — our legal team signs same-day.

Beyond single-document work, we bundle end-to-end packages for clients preparing multiple certificates at once — e.g. a "moving abroad" bundle (house registration + birth + marriage + diploma + transcript with MFA + embassy) that reduces the number of trips and total lead time versus filing each item separately. Approval remains at the discretion of the receiving authority; contact our team for scope and fees.

What sets us apart is a 15-year direct working relationship with the destination authority — BOI One-Stop Service Center (OSSC) + Department of Employment — so we anticipate regulation changes, format tweaks, and queue timing before they hit your case, and brief you in advance. Approval outcomes always remain at the sole discretion of the authority; what we control is document completeness, formatting and lodgement timing.

Service Knowledge Base

Work permits, BOI/IEAT privileges, Treaty of Amity and APEC card — practical answers

First-party answers on Thai work authorisation: the standard Department of Employment route, BOI and IEAT channels for skilled experts, US company rights under the Treaty of Amity, and the APEC Business Travel Card for Thai nationals — including which supporting documents must be translated and legalised first. (19+ search topics covered)

How are foreign degrees and experience letters handled?

They usually must be translated into Thai or English as required and legalised through the diplomatic chain: certified in the issuing country (apostille where that country is a Convention party), then endorsed by the Royal Thai Embassy, or endorsed by that country's embassy in Thailand and then legalised by the Legalization Division of the Department of Consular Affairs before submission.

Why are Thai work permit applications commonly returned?

The usual reason is that the job title and duties in the application do not match the employer's supporting documents, such as the company affidavit, financial statements and employment contract. Other frequent causes are qualifications claimed without properly certified translations, and applying under a business activity that is not among the objectives registered with the Department of Business Development. Map every document to the same set of facts before filing and confirm the current requirements with the Department of Employment office responsible for the workplace.

What happens to the permit if I change employer or job title?

Authorisation is granted by reference to the employer, workplace and described duties, so a change in any of them normally requires a filing rather than a private arrangement. Continuing to work under the old permit after the change is treated as unauthorised work. Plan the change with the new employer before resigning, because the gap between employments also affects the underlying permission to stay.

What happens if the permit lapses while renewal is pending?

Renewal must be filed before expiry within the period set by the regulations, and the permitted-to-stay end date must be tracked alongside it because the two dates do not always coincide. A lapse can force a restart and affect immigration status. Set calendar reminders several weeks ahead and keep current employer documents ready before the deadline.

Do I need a work permit for remote work for a foreign company?

This is fact-specific. The law addresses work performed within the Kingdom rather than only the location of the payer. Visas designed for remote workers carry their own conditions and do not automatically confer the right to work for a business in Thailand. Where Thai clients or a Thai entity become involved, obtain advice before starting to avoid regulatory exposure.

How do we get exact fees and timelines?

Processing times and official fees vary by application type, receiving office, document completeness and local queues, so fixed figures on a web page would be misleading. Our team quotes case by case after reviewing the actual documents — contact us by phone, LINE or email.

Does Treaty of Amity status remove the work permit requirement?

No. The treaty concerns the company's right to do business, not an individual's right to work. US executives and staff still need an appropriate visa category and a work permit under the same rules as other foreign nationals.

What does the BOI channel change?

Promoted companies can request approved skilled or expert positions through the BOI e-Expert system and complete visa and work permit formalities at the One Stop Service Center. Conditions and validity depend on the promotion certificate and the approved position, so a company should confirm its certificate conditions before planning foreign headcount.

Thai work permit — company-side and employee-side documents

Work permits are issued by the Department of Employment and are tied to the employer, position and workplace. Changing job, role or location requires a new filing.

Documents to prepare

  • Company side: current affidavit, shareholder list, financial statements, social security filings
  • Employee side: passport, the correct visa category, and the required medical certificate
  • Degrees and experience letters, legalised at source and translated for Thai use
  • Employment contract and job description
  • Workplace map and photographs where requested
  • Power of attorney for the company's filing agent

Step-by-step process

  1. 1. Check company and role eligibility Registered capital, Thai-to-foreign staff ratio and reserved occupations are verified first.
  2. 2. Prepare foreign documents Qualifications and experience letters must be legalised abroad and translated before filing.
  3. 3. File the application Through the Department of Employment, or a dedicated channel such as the BOI One Stop Service.
  4. 4. Collect and comply Work only within the stated role and location, and renew before expiry.

Pitfalls and rejection causes

  • Working outside the stated role or location breaches the permit conditions.
  • A permit belongs to the employer — it cannot follow you to a new company.
  • Visa and permit expire on different dates; track both.
  • Company documents older than the accepted window must be reissued.

Tips from our team

  • Set reminders at least 45 days before either expiry date.
  • Maintain a standing company document pack to speed up future filings.
  • BOI-promoted companies should use the dedicated channel to cut steps.

We handle the full chain — obtaining certified copies, translation, certification and submission — and keep you updated at each step. Reach us on LINE, phone or email during business hours.

Route Comparison

Comparing Thai work permit routes

Different employer types use different channels, and each channel pairs with a different visa category.

RouteWhen to useCertifying authorityApprox. durationRejection risk
Standard filing with the Department of EmploymentThe employer is an ordinary Thai company without BOI promotionDepartment of Employment, Ministry of LabourVariable, driven by how complete the employer's file isThai-to-foreign staff ratios and registered capital not meeting thresholds is the common refusal ground
BOI-promoted company channelThe employer holds a promotion certificate and the position is on the approved listBOI together with the Immigration Bureau and Department of EmploymentGenerally faster than the standard route, still variableA position that differs from the approved list requires an amendment first
Conditional or short-term work authorisationShort assignments or job types covered by specific published rulesDepartment of Employment under the notification in forceShorter than a full applicationWorking beyond the authorised scope is an offence even when a permit exists

Timelines above are practical estimates from live casework and can change with each authority's policy; confirm with the receiving authority before booking travel. If you would rather not test routes by trial and error, our advisers can assess which route fits your case.

Advisory Service

We do not just process documents — we advise you through the whole case

Our team has worked on cross-border documents, certified translation and government liaison for over 15 years. Most rejections we see are not caused by missing paperwork but by choosing the wrong route on day one, so we always start with a case assessment.

Route assessment

We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.

Pre-submission review

Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.

Timeline planning

We sequence the steps around your appointment or travel date and flag bottlenecks in advance.

Rejection recovery

We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.

Practical Q&A

Practical questions · Near me / DIY / Required documents

Where is a Thai work permit filed, and must the employee attend?

Applications are filed with the Bangkok area employment office or the provincial employment office covering the workplace, under the Department of Employment, Ministry of Labour. Some categories can be filed through the e-Workpermit system. An employer or authorised representative may file, but the employee may still be asked to appear. We can assemble and pre-check the document set; contact our team by phone, LINE or email.

How must foreign supporting documents be translated and certified?

Foreign degrees or experience letters are first certified in the issuing country and by the relevant embassy, then translated into Thai or English as required by the receiving office, and finally legalised by the Legalization Division of the Department of Consular Affairs. Doing these steps out of order is the most common cause of rejection.

Can I handle the application myself?

Yes, the Department of Employment procedure is open to applicants and employers. Delays usually come from outdated forms, company documents older than the office accepts, and translations that do not match the required format. Check the current checklist of the office you will file with before you start.
Practical advice & cautions

Business licensing and BOI: advice and cautions

Before you start
  • Plan licences together with work permits for foreign executives

    Thai-to-foreign staff ratios and registered capital determine how many work permits you can obtain. Design the staffing structure early to avoid emergency capital increases.

  • Treat product and premises permits as separate from the business licence

    Company registration does not authorise sales. Food, cosmetics and medical devices require FDA Thailand registration, and production or storage premises are inspected separately.

  • Legalise parent-company documents through the full chain

    Affidavits, financial statements and powers of attorney usually need notarisation abroad, government or embassy authentication, then Thai translation and legalisation by the Legalization Division, Department of Consular Affairs.

  • Draft company objectives to cover, but not exceed, what you need

    Objectives registered with the Department of Business Development must cover the licensed activity. A mismatch forces an amendment of the affidavit first, typically costing weeks.

Common reasons documents get rejected
  • Assuming a BOI certificate covers every activity

    Incentives attach only to the promoted activity and its stated conditions. Revenue from non-promoted activities must be accounted for separately and taxed normally.

  • Foreign documents older than the accepted validity window

    Parent-company affidavits and powers of attorney often have a validity period from issue. A slow legalisation chain can expire them before filing, forcing a fresh set.

  • Using nominee Thai shareholders

    Holding shares on behalf of a foreigner without genuine investment breaches the Foreign Business Act, and the source of Thai shareholders' funds can be examined. We do not assist with such structures.

  • Ignoring post-approval reporting duties

    Most licences require periodic reporting, renewal or notification of changes. Missing these can lead to revocation even when the business operates normally.

Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.

Choosing a document translation provider in Thailand

Pick a translation provider by the destination, not by turnaround alone. If the file goes to the Thai Department of Consular Affairs or an embassy, the translator must know the format that office accepts, not just the meaning. Verify three things: the certifier is named and identifiable, the destination accepts that certification format, and names, dates and document numbers match the passport character for character.

How to evaluate a provider

  • The certifier is named and identifiableConsular offices and embassies check who certified the translation, not only the wording.
  • Knows the format the destination acceptsEach embassy differs: attached source copy, letterhead, or prior consular legalization.
  • Character-level verificationMismatched name spelling and dates against the passport is the most common rejection cause.
  • Owns corrections after rejectionSubmissions run on appointment dates; slow corrections cost the applicant the slot.
  • Documented custody of originalsSome civil registry documents are hard to reissue, so intake and return must be traceable.

Questions to ask before you commit

  1. If the receiving authority rejects or asks for changes, do you correct it, and under what terms?
  2. How can I track status, and who physically holds the original documents?
  3. Who will certify this translation, and will the certifier be named on the document?
  4. Does my destination require consular or embassy legalization afterwards?
  5. How many working days does it actually take, counted from a complete file?

Your options, and who each suits

OptionBest forWhat to know
Freelance translatorInformal use where no authority certification is requiredMany embassies will not accept an uncertified translation.
Translation agency with certificationVisa, study and civil registry filingsConfirm the agency also handles the legalization step if the destination requires it.
End-to-end provider (translate + legalize)Files with a fixed appointment deadlineAsk which steps are in-house and which are subcontracted.

FAQ on choosing a provider

Which translation service is recommended for embassy submissions?
Choose one that names the certifier on the translation, knows the exact format your embassy accepts, and verifies names and dates against the passport before certifying. Ask whether they also handle consular legalization so the file does not stall between two vendors.
Does a cheaper translation get rejected more often?
Rejection correlates with format and verification, not price. A translation is rejected when the certifier cannot be identified, the layout does not match the receiving office's requirement, or a name or date differs from the passport.
