Complete guide: LTR Visa (10-Year) + BOI Smart Visa — Long-Term Resident Visa for HNW Individuals, Highly-Skilled Professionals, Executives, Investors, Startup Founders & Wealthy Pensioners (17% Flat Tax • No 90-Day Reporting • Airport Fast-Track)

Topic 01 · Add-on services worth considering

Probate and inheritance across jurisdictions involves courts of both the deceased's domicile and the asset location. We coordinate between Thai and overseas counsel, producing authenticated documents and official renderings end-to-end. 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.

Topic 02 · Education credentials for WES / IQAS / ICAS evaluation pipelines

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 03 · Scholarship and research grant documentation packages

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 case holders (1–2 extra business days). Common destination-specific traps: USCIS rejects language 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 04 · Service fees and turnaround time

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 maintain a living checklist of destination-authority quirks updated every Monday from MFA notices, diplomatic mission 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 applicants put us on retainer rather than tendering each file separately.

Topic 05 · Post-delivery follow-up

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. 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 + consular post chain because their own implementation has not caught up.

Topic 06 · Original and controlled-copy handling

Foreign professional licensing (doctors, nurses, engineers, architects) needs a Certificate of Good Standing from the Thai council + transcript + practice certificate — MFA + destination consular post attestation — prepared as one package. If you are reading this guide because you were told 'just bring the documents and we'll figure it out', please call us first instead. The single most expensive mistake in this entire industry is starting work on the wrong certification path; a thirty-minute call costs nothing and routinely saves service users five-figure sums in repeat fees.

Topic 07 · 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-officially recognized and notarised. We hold templates for Fulbright, Chevening, DAAD, and Monbukagakusho. Foreign case holders 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 customer's preferred channel. We answer within two business hours during Bangkok working time.

Topic 08 · Digital Nomad Visa and Remote Work Visa document stacks

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. We routinely handle files for case holders 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 09 · Citizenship application and renunciation document handling

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. 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 diplomatic mission quirks.

Topic 10 · Document risk assessment criteria

Cross-border corporate filings (Certificate of Incorporation, Board Resolution, Power of Attorney) move through the full stack: Lawyer → DBD → MFA Document attestation / Certification → Destination Diplomatic mission — full chain delivered in 7-10 business days. 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 11 · Asset documentation for outbound FDI and treasury filings

Our Destination Matrix indexes document requirements across 195 destination countries, refreshed quarterly from official consulate sources — service users get precise pre-filing guidance and avoid wrong-document-type submission. If your matter touches a Thai court, immigration tribunal, or arbitration panel, the language conversion 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 12 · Accounting and financial statements for cross-border business

Consular post 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. 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.

Topic 13 · Confidentiality and personal data (PDPA) handling

Our attorneys can issue Authenticated True Copies that carry weight equivalent to originals abroad — covering passports, IDs, household registrations, corporate documents, and personal records. Corporate customers 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 14 · Sample cases and lessons learned

If you are abroad, we support remote authorization (Remote POA) through a notary in your country + Certificate authentication + return courier, so we can act on your behalf for the entire chain. We publish our internal QA stats quarterly to customers 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.

Topic 15 · Documents and information you need to prepare

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. 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.

Topic 16 · Common mistakes and how to avoid them

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. 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 17 · Notes for corporate and institutional clients

When engaged parties need the same documents in multiple destination countries, we prepare parallel copy sets with Authentication / MFA separately per country — 30-40% cheaper than running each one individually, and delivered in a single batch. 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.

Topic 18 · Relevant legal requirements

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 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. Case holders may invoke Right-to-Erasure at any time and we comply within seven days.

Topic 19 · Standard turnaround vs rush service

For US / Canadian credential evaluation through WES, IQAS (Alberta), or ICAS (BC, MB) we prepare a standard three-piece set: original transcript + officially recognized diploma copy + translator-duly verified certified translation — couriered directly to the evaluation body. Pricing transparency matters: every quote breaks out government fees, courier, translated copy 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 20 · Name-match resolution via Affidavit of One and the Same Person

Each destination has its own quirks: the US wants state-level Certification, the UK uses FCDO Consular endorsement, Australia accepts NAATI without Certificate authentication, China requires diplomatic mission authentication, Japan often demands diplomatic mission-aligned language conversion. We document everything for repeat business. If you used us in 2024 for a marriage registration and come back in 2026 to apostille 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.

Key takeaways

  • Outcomes rest solely with the deciding authority; no provider can promise a particular result
  • Foreign-language documents usually require translation and certification
  • Always check the official embassy or immigration website for current criteria
  • This page is general information, not case-specific legal advice

Additional frequently asked questions

How are marriage and birth records used for dependant visas?
Use the registrar-issued marriage certificate or birth certificate with a certified translation and the legalisation chain the embassy specifies. Some countries accept only recently reissued copies.
Is a police clearance certificate always required?
Not for every visa class, but work, permanent-residence and many long-stay student visas require one, issued within the recency window stated by the immigration authority.
Can documents be submitted in Thai?
Foreign embassies generally do not accept Thai-language documents without translation; a certified English translation, or one in that country's official language, must be attached in the prescribed format.
When can a refused application be resubmitted?
Usually as soon as the stated refusal ground is remedied, but read the decision letter carefully — some countries impose a waiting period or direct applicants to an appeal route instead.
What company documents are needed for business visas?
Typically a company affidavit, an invitation letter from the counterparty and an employment or position letter, each with translation and certification as the embassy requires. Scope and requirements are confirmed case by case by phone, LINE or email.
How far ahead should preparation start?
Several weeks before travel: issuing public records, translating and each certification layer all have their own queues, and some documents must be less than 3–6 months old on submission.

How this connects to the next step

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.

In depth: the real requirements and why documents get rejectedVisa supporting documents

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.

Conditions you actually have to clear

  • Names across every document must match the passport; where an older document uses a former name, evidence of the change must be attached.
  • Financial evidence must be issued by the institution and show movement, not an application screenshot.
  • Relationship evidence such as a marriage certificate or birth certificate must be recently issued if the destination sets an age limit.

Common causes of rejection

  • Translations with no identified translator or certification statement, which are treated as unusable.
  • Over-filing to the point where the key evidence is buried and the assessor cannot locate it.

With a fixed travel date, plan backwards from the filing date and allow for issuing times at source, which no agent controls.

Which authority is competent for Accounting, tax and payroll?

Ask our staff by phone, LINE or email for scope and timing (we do not publish fees on the page because they depend on the document type and destination). This is general guidance; requirements and processing times change — verify with the competent authority before filing.

How long does Accounting, tax and payroll take?

Turnaround is not fixed: it depends on the queue and rules of Revenue Department, DBD and Social Security Office, the document type, and the receiving office abroad. For that reason we do not publish a fixed figure. Plan a buffer before your real deadline and ask our staff by phone, LINE or email for the current queue before booking travel. This is general guidance; requirements and processing times change — verify with the competent authority before filing.
