BOI application documents

After BOI approval

  4. File Royal Decree 743 separately if W/WGC/T — not automatic
  5. Annual BOI reporting

Rejection patterns

Crypto-only assets; insurance wrong wording; fake employer letters; T category with Thai clients; incomplete 2-year income history.

Pattaya applicants

BOI processing Bangkok-centralised — Pattaya residence fine post-approval. Plan Thai bank account for WGC investment components. RD 743 filing with Pattaya accountant familiar with LTR — not all accountants handle RD 743.

Timeline expectation

Document gathering 4–8 weeks. BOI review 4–12 weeks category-dependent. Embassy visa 1–2 weeks. Total 3–6 months realistic — do not book irreversible Pattaya property deposit on hoped 6-week LTR approval.

Health insurance BOI wording

Policy must state coverage in Thailand, USD 50,000 minimum, inpatient — outpatient-only fails. Some insurers sell BOI-specific certificate page — request explicitly.

Dependent LTR

Spouse and children separate LTR dependent applications linked to primary — additional financial proof. Pattaya families relocating together plan ฿50K+ legal/accounting bundle.

Professional category T employer letter

Must state remote work, no Thai clients, employer 2+ years operating, salary USD 80K+ — template letters from BOI website — employer deviating wording causes rejection resubmit cycle 4 weeks.

Criminal record certificate validity

Most countries issue criminal record valid 6 months — BOI application timing must fit certificate window. Order certificate early — UK DBS, US FBI, German Führungszeugnis weeks processing.

Post-approval Pattaya setup

LTR approved: open Thai bank account for WGC investment, file TM30, register T-category activity, engage accountant for RD 743 first tax year — missing RD filing loses exemption that year.

W category: pension letter must show indefinite continuation — term pension ending in 3 years may fail. Social security statements need apostille US UK AU.

Register BOI portal account before documents arrive — password reset delays upload window.

H category highly skilled: 17% tax cap benefit separate from RD 743 — confirm employer on BOI-targeted company list before resigning home country role.

Wealthy Global Citizen USD 500K Thailand investment: verify fund or asset class on BOI approved list before transfer — wrong investment type means re-source funds and delay months.

Allow two extra weeks buffer beyond BOI quoted timeline for document requests.
