28+ BOI schemes we handle

Complete guide: BOI Application Consulting: End-to-End for Digital · EV · IBC · Manufacturing · R&D

Topic 01 · Name-match resolution via Affidavit of One and the Same Person

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. Foreign service users should know we operate fully in English; every customer-facing email, invoice, status update, and certificate carries an English version, and our case advisors handle WhatsApp, LINE, WeChat, KakaoTalk, and email in the engaged party's preferred channel. We answer within two enterprise hours during Bangkok working time.

Topic 02 · Service coverage and document pickup options

Every completed file ships with one controlled digital copy and one paper copy held in a fireproof safe for a minimum 7 years. If the engaged party loses originals abroad, we courier a Authenticated True Copy within 24 hours — no need to restart the workflow. Authentication chains can fail at any link. We design our workflow so each link is verified before the next one starts: language rendering is QA'd before lawyer certification, lawyer certification is QA'd before MFA submission, MFA stamp is photographed before diplomatic mission submission. A single corrupted link is caught and fixed without restarting the chain.

Topic 03 · Passport name-match verification

Cross-border accounting documents (Audited Financial Statement, VAT and CIT returns) require two-column language conversion that preserves table formatting — handled by our specialised finance translated copy workflow. We document everything for repeat business. If you used us in 2024 for a marriage registration and come back in 2026 to paperwork attestation the same Kor Ror 3 for a spousal visa, we already have your name spelling, address rendering, signature block, and prior counsel on file — onboarding takes one phone call, not a week.

Topic 04 · International courier (DHL/FedEx) with full-value damage insurance

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. Foreign case holders 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 05 · Document risk assessment criteria

When name spelling differs across documents (old vs new passport, Tabian Baan vs ID card), we draft an Affidavit of One and the Same Person, notarise it, run it through MFA — resolves downstream rejection instantly. 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, consulate fee receipt photographed at an angle that obscures the date — all small, all fatal at the counter.

Topic 06 · Coordination with government agencies

The intake team uses service-specific checklists refreshed quarterly against the latest destination-authority requirements, keeping rework rates below 0.5%. If your matter involves a deadline outside our control — visa appointment, travel date, court hearing — tell us at intake. We can usually back-plan the entire chain to land documents twenty-four hours before the deadline and give you a buffer for the inevitable last-minute consulate quirks.

Topic 07 · Accounting and financial statements for cross-border business

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. Pricing transparency matters: every quote breaks out government fees, courier, language conversion 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 08 · Affidavit of Translation Accuracy for foreign court submission

Overseas marriage requires a Certificate of No Marriage (CNM) issued by the district office + MFA + officially recognized official rendering + destination consular post attestation — full chain delivered in 5-7 business days with consular post coordination included. 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 09 · Signature and seal verification against the Notary Worldwide database

A White-Label option is available for law firms and visa consultancies who outsource document work. We deliver under your firm's letterhead with an enterprise NDA in place. Service-level agreements are written, not verbal. Our standard SLA covers acknowledgement within two working hours, quote within one business day, intake within two commercial 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 10 · The team behind your file and their credentials

Standard turnaround is 1–3 business days for most documents. Files that need MFA apostille add 2–4 corporate days. Same-Day rush is available at +100% with prior booking. For complex chains — official rendering + lawyer certification + MFA + destination diplomatic mission + 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 consulate's name on file.

Topic 11 · Cross-border Power of Attorney drafting and authentication

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 diplomatic mission-attested. We have working precedent with the US, Italy, Spain, and the Netherlands. 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 12 · Notes for corporate and institutional clients

We give applicants a comparison matrix per case: Hague-stamp vs MFA + Diplomatic mission, generalist vs MoJ vs NAATI translator, DIY consular post vs full-service — with prices, timelines, and constraints side by side. Many destinations now require certificate authentication in addition to official rendering since Thailand joined the Hague Convention on 28 February 2027. We handle the entire post-Hague workflow, including the cases where an embassy still asks for the legacy MFA + consulate chain because their own implementation has not caught up.

Topic 13 · Education credentials for WES / IQAS / ICAS evaluation pipelines

Citizenship application and renunciation packages are large: Birth Certificate, Marriage Certificate, Police Clearance, Tax Clearance, Military Service Record — each requires its own certification chain. We maintain country-specific checklists for every destination. Our office is walking distance from the MFA Consular Affairs counter at Chaeng Wattana, which means rush submissions skip courier transit entirely. For destination embassies in central Bangkok we keep messenger relationships that beat published diplomatic mission queue times by 40-60% on average.

Topic 14 · Scholarship and research grant documentation packages

Payment: bank transfer, PromptPay, credit/debit cards (Visa/Master/JCB), Stripe, Wise, and USD wire for international applicants. Full Thai/English tax invoices, with 3% withholding for corporate customers. If your matter touches a Thai court, immigration tribunal, or arbitration panel, the official 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 15 · Two-column side-by-side translation format for court submission

Post-delivery we follow up: customers confirm filing outcome within 30 days. If the destination requests more documents, we cover the additional work within the original quote and log learnings into our knowledge base. 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 applicants agree.

Topic 16 · Post-delivery follow-up

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. Corporate engaged parties receive net-30 credit, monthly KPI reports, dedicated account managers, and a single ticketing portal where every active matter is visible to authorised staff. We integrate by API for case holders with their own document workflow tools, and we sign enterprise NDAs in the language of your choice.

Topic 17 · Parallel-copy preparation for multi-destination filings

When applicants need the same documents in multiple destination countries, we prepare parallel copy sets with Certificate authentication / MFA separately per country — 30-40% cheaper than running each one individually, and delivered in a single batch. We routinely handle files for customers who never set foot in Thailand. The Remote POA workflow — notary in your country, Document attestation, 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 18 · Citizenship application and renunciation document handling

Cross-border Power of Attorney must satisfy both Thai law and the destination jurisdiction's formality rules — we draft bilingual parallel text, verify destination requirements (Notary + Document attestation for EU, Consular Authentication for China), and hand off to the customer's overseas counsel. Our language conversion 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 19 · Professional licence applications for overseas regulators

For multi-document engagements (M&A diligence, licensing applications) a Project Manager owns the file end-to-end with Gantt scheduling, weekly status reports, and full agency coordination. Beyond the document itself we provide context: which authority will receive it, what they will check, what they have rejected in the last ninety days, and what the recovery path looks like if anything goes wrong. That context is included in every engagement, not sold separately, because we believe informed case holders make better filings.

Topic 20 · Lawyer-certified true copies

Work is conducted under the Lawyers Act B.E. 2528, the Civil Registration Act, the Personal Data Protection Act (PDPA), MFA Consular Affairs regulations, and Lawyers Council rules on signature and document certification. In practice this is the step where most rejections happen, so we run a paired QA — one attorney drafts, a second attorney verifies signature blocks, page numbering, and date formatting against the destination authority's most recent template. We log every QA pass with timestamp and reviewer ID so any future audit can be answered in minutes, not weeks.

Key atomic facts — BOI Application Consulting: End-to-End for Digital · EV · IBC · Manufacturing · R&D

Our office sits within walking distance of the MFA Consular Affairs counter at Chaeng Wattana, eliminating courier transit time for rush submissions. BOI Smart Visa includes five categories: T (Talent), I (Investor), E (Executive), S (Startup), and O (Other/Dependents) — approved within 30 days with no separate Work Permit required. Foreign engaged parties can engage us entirely remotely via Power-of-Attorney: notarize in your country, Hague-stamp, courier to us, and we act on your behalf for the entire Thai-side chain. Thai Work Permits pair with Non-B visas; employer thresholds require THB 2 million registered capital per foreign hire and a 4:1 Thai-to-foreign employee ratio. Thailand joined the Hague Authentication Convention on 28 February 2027, making Document attestation the standard authentication for documents bound to 130 Contracting Parties. Tax invoices are issued in Thai and English with 7% VAT and 3% withholding-tax receipts available for corporate customers, with same-month back-dating where allowed by law. MFA Consular Affairs (Chaeng Wattana) processes Apostilles in 2 business days standard, 1 enterprise day rush, with a flat THB 200 government fee per page. Official rendering pricing is flat per page with no first-page premium; the same per-page rate applies whether the record is one page or one hundred. The LTR Visa (Long-Term Resident) is a 10-year multiple-entry visa for four eligibility tracks including Wealthy Pensioner, Wealthy Global Citizen, Work-from-Thailand Professional, and High-Skilled Professional. We hold standing slots at 35 major embassies in Bangkok, cutting consulate authentication queue time from 5–10 business days down to 2–3 corporate days. Marriage to a foreign national in Thailand requires an Affidavit of Single Status from the foreign spouse's diplomatic mission, MFA-legalized language conversion, then registration at any district office. Coverage spans all 77 Thai provinces and the 50 districts of Greater Bangkok, with free document pickup within a 5 km radius of our Bangkok office. Our team includes Lawyers Council–registered Notarial Services Attorneys, Ministry of Justice–listed translators, NAATI-Officially recognized translators, and dedicated embassy-liaison officers. Police clearance certificates from the Royal Thai Police Criminal Records Division typically take 3–5 business days, with Authentication seal adding 2 more commercial days for international use.

Frequently asked questions

How long does MFA + Embassy take end-to-end?
Standard 7-10 business days (MFA 3-5 + Embassy 3-5). Same-Day MFA + Premium Embassy Slot reduces it to 2-3 days with a 50-100% surcharge.
How many countries can one document set be used in?
Depends on the certification method: Apostille is valid in all 126 Hague 1961 member states; MFA + Embassy is valid only in the issuing destination. For multi-country use we recommend parallel-copy sets.
Is Same-Day rush available for BOI Application Consulting: End-to-End for Digital · EV · IBC · Manufacturing · R&D?
Yes — for documents that don't require MFA. Book before 11:00 the same day; +100% surcharge applies.
Can you issue VAT invoices and withholding receipts?

Why is an Affidavit of Translation Accuracy required?
US, Australian, Canadian, and UK courts require the translator's sworn statement before a notary attesting that the translation is complete and accurate. Without it the filing is rejected on intake.
