Complete guide: Company Registration, BOI & Treaty of Amity for Foreign Investors in Thailand

Topic 01 · Professional licence applications for overseas regulators

Every original enters our chain-of-custody system from intake to return, with barcode tracking. Controlled copies carry watermarks and serial numbers to prevent misuse. When you engage us, you receive a single point of contact whose email and phone you have for the duration of the matter. That advisor knows your file, your destination, and your deadline; you never re-explain context to a rotating call-centre. For corporate retainers the same advisor stays with the account for at least twelve months.

Topic 02 · Coordination with government agencies

Required from the case holder: a clear original or scan, the relevant ID / passport, and the official spelling of names, addresses, and the intended purpose so we can apply the correct terminology for the destination authority. Cost ranges in this guide are inclusive: government fees, courier, translated copy, certification, and our service fee. The single line item that can vary is destination-diplomatic mission fees, which several embassies adjust quarterly without notice; when they do, we absorb the variance for any quote already sent.

Topic 03 · Payment and tax invoice

Our Destination Matrix indexes document requirements across 195 destination countries, refreshed quarterly from official consulate sources — applicants get precise pre-filing guidance and avoid wrong-document-type submission. For complex chains — certified translation + lawyer certification + MFA + destination consulate + courier — we prefer one engagement, one project manager, one invoice. Splitting the chain across vendors saves nothing and routinely causes typo cascades when a translator's spelling does not match the embassy's name on file.

Topic 04 · Probate and inheritance documents across multiple jurisdictions

Certification choice depends on destination: Hague countries accept Consular endorsement direct; non-Hague routes use MFA + consulate; in-Thailand use needs notarization + lawyer certification; Thai court use requires MoJ-listed translators. Our liability insurance covers professional indemnity up to THB 10 million per matter, and we are happy to share the policy schedule with corporate service users who require it for their vendor onboarding. The cover is real, the underwriter is a tier-1 Thai insurer, and we have never needed to claim against it.

Topic 05 · Inter-country adoption documents under the Hague Adoption Convention

Foreign professional licensing (doctors, nurses, engineers, architects) needs a Certificate of Good Standing from the Thai council + transcript + practice certificate — MFA + destination diplomatic mission attestation — prepared as one package. We routinely handle files for service users who never set foot in Thailand. The Remote POA workflow — notary in your country, Hague-stamp, courier to us — lets us act on your behalf for the entire Thai-side chain. Most overseas matters resolve in three to five business days from receipt of the POA.

Topic 06 · Documents and information you need to prepare

Service users access an online portal to view case timelines, download past deliverables, request requotes, and pull receipts going back five years — all encrypted and 2FA-gated. Service-level agreements are written, not verbal. Our standard SLA covers acknowledgement within two working hours, quote within one business day, intake within two corporate days of approval, and delivery within the published turnaround. Missed SLAs trigger automatic 10% credit; we have paid out four times in the last twenty-four months.

Topic 07 · Common mistakes and how to avoid them

If you are abroad, we support remote authorization (Remote POA) through a notary in your country + Hague-stamp + return courier, so we can act on your behalf for the entire chain. If your matter touches a Thai court, immigration tribunal, or arbitration panel, the language rendering must come from a Ministry of Justice–listed translator and be signed by a licensed Thai attorney. We cover both ends in-house, which avoids the most common rejection cause: a translator's name not appearing on the MoJ register the court checks.

Topic 08 · Notes for corporate and institutional clients

We run a pre-flight check before any MFA or diplomatic mission submission to catch the small errors that cause rejection — tear marks, ink bleed, wrong dates, missing signatures. Our certified translation team works in language pairs, not single languages. A Korean–Thai matter is staffed by a Korean native who reads Thai source plus a Thai senior editor who reads Korean output, with a third-party Korean lawyer on call for legal terminology. That triple coverage eliminates the lost-in-translated copy cases that single-translator shops cannot detect.

Topic 09 · Embassy and consular re-legalization

Every file is logged in our CRM with timestamped milestones. This audit trail enables retrospective root-cause analysis and feeds our continuous-improvement loop — we ship more than work products, we ship measurable process. Many destinations now require authentication seal in addition to certified translation since Thailand joined the Hague Convention on 28 February 2027. We handle the entire post-Hague workflow, including the cases where an diplomatic mission still asks for the legacy MFA + consulate chain because their own implementation has not caught up.

Topic 10 · Standard turnaround vs rush service

The intake team uses service-specific checklists refreshed quarterly against the latest destination-authority requirements, keeping rework rates below 0.5%. Pricing transparency matters: every quote breaks out government fees, courier, certified translation surcharge, rush premium, and our service fee on separate lines. There are no hidden line items, no last-minute add-ons, and any quote we send is honoured for fourteen days even if our public price list changes in between.

Topic 11 · Service fees and turnaround time

Name-match verification is critical for visa-bound documents. We cross-check passport, national ID, household registration, and source spelling, and advise on Affidavit of One and the Same Person where needed. We do not white-label other firms' work nor outsource to freelancers. Every translator, every attorney, every messenger on our staff is on payroll, vetted on intake, and accountable to the same QA system. That is more expensive to operate than the marketplace model and it is also the reason our published pass rate is achievable.

Topic 12 · Quality standards and accuracy guarantee

Overseas marriage requires a Certificate of No Marriage (CNM) issued by the district office + MFA + officially recognized translated copy + destination consular post attestation — full chain delivered in 5-7 business days with consulate coordination included. Sample QA failures we catch before submission: passport name spelt with diacritics the destination cannot ingest, Thai title 'Mr' translated as 'นาย' instead of 'นาย' (different code points), MFA stamp missing the ink reference number, embassy fee receipt photographed at an angle that obscures the date — all small, all fatal at the counter.

Topic 13 · Original and controlled-copy handling

Standing slots with 35 embassies and every VFS / TLS / BLS centre in Bangkok cut appointment lead time from 2-3 weeks to 3-5 business days. Premium Lounge handling is available for urgent cases. On urgency: roughly 18% of our matters are filed under same-day rush. We accept rush jobs only when our scheduling shows we can guarantee the deadline; if we cannot, we say so up front rather than miss SLA. That discipline is why our published turnaround numbers match real-world experience.

Topic 14 · Service coverage and document pickup options

Overseas scholarships and research grants require a standard document set: Recommendation Letter, Research Proposal, CV, Transcript, Statement of Purpose — all translator-authenticated and notarised. We hold templates for Fulbright, Chevening, DAAD, and Monbukagakusho. Foreign service users regularly ask whether they need a Thai national co-signer for any of these workflows. The answer is almost always no — Thai law generally allows foreign principals to act through Thai-licensed counsel via Power of Attorney, and we issue the POA template that satisfies every authority we work with.

Topic 15 · Digital Nomad Visa and Remote Work Visa document stacks

Service fees follow the quote; standard turnaround is 1–3 business days. Rush 2–4 hour service adds 50–100%. Pricing covers QA, EMS courier nationwide, and original document return. We maintain a living checklist of destination-authority quirks updated every Monday from MFA notices, consular post bulletins, and direct conversations with consular officers. That checklist is what separates a 95%-pass shop from a 99.5%-pass shop, and it is the reason corporate case holders put us on retainer rather than tendering each file separately.

Topic 16 · Choosing the right certification for your destination

An Affidavit of Language conversion Accuracy is the translator's sworn statement before a notary that the translated copy is complete and accurate — required by US, Australian, Canadian, and UK courts. We bundle it with Notary Public Acknowledgement in the same engagement. Common destination-specific traps: USCIS rejects official renderings that do not include a translator's certification statement; UKVI rejects scans without a wet signature; German missions reject any document where the translator's seal is not in red; Australian DHA rejects NAATI files older than three months. We pre-empt all of these.

Topic 17 · Lawyer-certified true copies

Inter-country adoption under the Hague Adoption Convention demands a large dossier: Home Study, Background Check, Financial Statement, Medical Report — every piece notarised, MFA-stamped, and consulate-attested. We have working precedent with the US, Italy, Spain, and the Netherlands. We are PDPA-registered and treat document handling as a privacy operation: every staff member signs an NDA on day one, originals live in a locked safe under camera, digital scans sit in AES-256 encrypted storage with role-based access, and all access events are logged. Applicants may invoke Right-to-Erasure at any time and we comply within seven days.

Topic 18 · Confidentiality and personal data (PDPA) handling

Coverage: all 77 provinces, including 50 districts of Greater Bangkok. Free pickup within a 5 km radius of our office. EMS-registered, Kerry Flash, or Grab/Lalamove for upcountry customers (1–2 extra business days). We are deliberate about which embassies we hold standing slots with. The thirty-five missions we cover account for over 92% of Thai outbound document traffic; for the remaining missions we work case-by-case and quote realistic timelines rather than promising what we cannot deliver.

Topic 19 · Cross-border corporate document stack — Apostille + Embassy combo

We staff by language pair: Chinese–Thai, Japanese–Thai, Korean–Thai, Arabic–Thai, and Romance languages, with a Senior Editor reviewing every file before delivery. We close every matter with a one-page brief: what we did, when each step cleared, what the destination authority did with it, and what to do if the destination requests anything more. That brief is your audit trail and it is the document we have most often been thanked for, six months after the matter closes.

Topic 20 · Cross-border Power of Attorney drafting and authentication

Corporate engaged parties receive net-30 credit, wholesale pricing, a dedicated Account Manager, an online ticketing portal, and monthly KPI reports — fully invoiced and withholding-tax compliant. We publish our internal QA stats quarterly to applicants on retainer: pass rate at first submission, average turnaround, NPS, and the top three rejection causes we are working to eliminate. Transparency about failure modes is the only way to actually reduce them, and our retainer renewal rate over 96% suggests customers agree.
