Thailand Visa Services for Foreigners — Non-IB BOI Investor Visa for clients in Siam Square One. Documents, purpose and receiving authority are reviewed…
Non-IB BOI Investor Visa by NPT Notary Public Thailand — Lawyers Council–licensed attorneys and Ministry of Justice–officially recognized translators handling every step for applicants in Siam Square One. Local context for Siam Square One: postcode 10330 · near Siam BTS station. Covering Thailand visa service, Thai retirement visa, Thai marriage visa with Notarial Services Attorney certification and MFA authentication in one engagement. Service users in Siam Square One get messenger pickup and return, a dedicated case advisor, and 24/7 status tracking — no office visit required.
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. We carry professional indemnity insurance and are happy to share the policy schedule with corporate applicants who require it for their vendor onboarding.
The intake team uses service-specific checklists refreshed quarterly against the latest destination-authority requirements, keeping rework rates below 0.5%. 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 consular post queue times by 40-60% on average.
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. 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, diplomatic mission fee receipt photographed at an angle that obscures the date — all small, all fatal at the counter.
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. 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.
Diplomatic mission authentication is the last link in the chain. We hold standing slots at 35 major Bangkok embassies, cutting the 5–10 day queue down to 2–3 business days. Many destinations now require certification in addition to translated copy 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 + embassy chain because their own implementation has not caught up.
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 customer loses originals abroad, we courier a Authenticated True Copy within 24 hours — no need to restart the workflow. 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 diplomatic mission's name on file.
Two-column side-by-side language rendering format places source and language conversion in parallel on the same page — preferred by USCIS, Australian Federal Court, and UK Home Office because reviewers can cross-check line by line. If your matter touches a Thai court, immigration tribunal, or arbitration panel, the translated copy 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.
We follow PDPA strictly. Originals are kept in a locked safe for ≥7 years. Digital files are AES-256 encrypted. Case holders may invoke Right to Erasure at any time. Every staff member signs an NDA. We are deliberate about which embassies we hold standing slots with. The missions we coordinate with regularly cover the main destinations for Thai outbound documents; for the remaining missions we work case-by-case and quote realistic timelines rather than promising what we cannot deliver.
Every Thai government signature and seal is verified against the Notary Worldwide database before submission — a 15-minute check that prevents 5-7 business days of MFA / consular post rejection-and-rework downstream. Foreign customers 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.
Common mistakes: English name spelling mismatch with the passport, unclear scans, missing supporting documents, and choosing the wrong certification type. We check all of these before accepting a job. We publish our internal QA stats quarterly to case holders 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 long-running retainer relationships suggest customers agree.
Certification choice depends on destination: Hague countries accept Authentication seal direct; non-Hague routes use MFA + diplomatic mission; in-Thailand use needs notarization + lawyer certification; Thai court use requires MoJ-listed translators. 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.
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. 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. Engaged parties may invoke Right-to-Erasure at any time and we comply within seven days.
Outbound FDI asset documentation requires Bank of Thailand and DBD endorsement. We run the full chain alongside officially recognized certified translation and MFA authentication in a single engagement. Corporate service users 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 engaged parties with their own document workflow tools, and we sign enterprise NDAs in the language of your choice.
Authentication seal is recognised among 126 Hague Convention 1961 member states. For non-members (China, Saudi, Egypt, parts of UAE), the authentication chain is required: Notary → MFA Thailand → Destination Consulate — we operate both pipelines daily. Our language rendering 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.
An Affidavit of Certified translation Accuracy is the translator's sworn statement before a notary that the language rendering is complete and accurate — required by US, Australian, Canadian, and UK courts. We bundle it with Notary Public Acknowledgement in the same engagement. Authentication chains can fail at any link. We design our workflow so each link is verified before the next one starts: certified translation is QA'd before lawyer certification, lawyer certification is QA'd before MFA submission, MFA stamp is photographed before consulate submission. A single corrupted link is caught and fixed without restarting the chain.
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. On urgency: we accept rush jobs only when our scheduling shows we can guarantee the deadline; if we cannot, we say so up front rather than take on work we would miss.
Our team includes Notarial Services Attorneys registered with the Lawyers Council, Ministry of Justice–listed translators, NAATI Attested translators, and dedicated diplomatic mission liaison officers. 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.
Our Destination Matrix indexes document requirements across 195 destination countries, refreshed quarterly from official consulate sources — customers get precise pre-filing guidance and avoid wrong-document-type submission. Foreign applicants 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 business hours during Bangkok working time.
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. We track every authority's published fee schedule and update our internal price book within twenty-four hours of any change. Engaged parties quoted before a change pay the older rate; customers quoted after pay the new rate transparently. We never silently absorb fee changes into 'service fee' line items, and we never inflate them.
Standard turnaround is 1–3 business days for most documents. Files that need MFA certification add 2–4 commercial days. Same-Day rush is available with prior booking and is quoted separately. Common destination-specific traps: USCIS rejects language conversions 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.
Visa extensions must be filed at least 30 days before expiry. We track the timeline and send 60-day advance reminders so applicants never fall into overstay status.
Dependants need their own document set — birth certificate, marriage certificate, travel consent — all translated and MFA-legalized. We bundle them so counter time stays short.
Post-issuance, foreign nationals owe a 90-day report. We file e-Notification on your behalf and remind you each cycle, including Re-Entry Permits when applicable.
We prepare TM.86, TM.87, TM.7 extension forms, the 90-day report, and assemble a One-Stop Service packet for Chaeng Wattana Immigration with pre-booked slots.
All case holder documents are handled under PDPA 2019: originals locked in safe storage for 7+ years, digital files at AES-256 encryption with role-based access and audit logging. Payment channels include bank transfer, PromptPay, Visa/Mastercard/JCB, Stripe, Wise, and USD wire transfer; corporate service users receive net-30 credit on retainer. Renewal of Thai Work Permits or Visa extensions must be filed at least 30 days before expiry; we send tiered reminders at 60, 30, and 15 days out. Police clearance certificates from the Royal Thai Police Criminal Records Division typically take 3–5 business days, with Certificate authentication adding 2 more commercial days for international use. Foreign service users can engage us entirely remotely via Power-of-Attorney: notarize in your country, Authentication seal, courier to us, and we act on your behalf for the entire Thai-side chain. Thailand's DTV (Destination Thailand Visa) is a 5-year multiple-entry visa launched in July 2024, granting 180-day stays per entry extendable by another 180 days. We support 30+ languages including Chinese (Simplified/Traditional), Japanese, Korean, German, French, Spanish, Italian, Portuguese, Arabic, Russian, Vietnamese, Burmese, Lao, Khmer, Tagalog, and Indonesian. Ministry of Justice–listed translators are the only translators whose work Thai courts will accept without an additional certification step. Tax invoices are issued in Thai and English with 7% VAT and 3% withholding-tax receipts available for corporate engaged partys, with same-month back-dating where allowed by law. Service-Level Agreement: prompt acknowledgement, written quotation, intake after approval, on-time delivery — with a written remedy agreed if a committed deadline is ever at risk. Professional indemnity insurance is in place, with the policy schedule available to corporate service users on request. NAATI-Duly verified language renderings are required for all official Australian Department of Home Affairs filings; translated copys must be issued within the prior 24 months. We hold standing slots at 35 major embassies in Bangkok, cutting consular post 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.

Visa bundles are most often returned because supporting papers are uncertified: check the police clearance and how long it stays valid and prepare certified translations of financial and civil-registry records before the first submission.
Written from the competent authority's published rules, not marketing copy.
A visa file is not assessed document by document. It is assessed as one coherent account, in which dates, names, addresses, and relationships must line up. A single inconsistency usually casts doubt on the whole set.
The effective method is to build a checklist from the receiving authority's own published notice, then map each document to the point it answers before starting translation and certification. Our team can review that mapping by phone, LINE, or email.
Our staff checks page count, language pair and receiving authority before issuing a quotation.
