A working guide to long-term resident (ltr) visa in Thailand
Long-Term Resident (LTR) Visa is one of the standing service lines that corporate legal departments, embassies, foreign universities, HR compliance teams, and immigration bureaux route their highest-stakes files to. The institutional posture — as opposed to a freelance translator or a generalist firm — is the deliberate reason receiving offices treat the deliverable as finished, not draft. Every high-net-worth, retirees, and remote professionals settling in Thailand matter is scoped by a senior specialist on LINE Official @NAATI or by email at ilc@thainotary.co.th before any file moves.
The document set most often audited on high-net-worth, retirees, and remote professionals settling in Thailand matters here includes passport, USD 500k investment or USD 80k income proof, health insurance USD 50k coverage, clean criminal record, employment contract (professional tracks), family relationship proof. Deliverables are formatted to the acceptance criteria of the Board of Investment (BOI) LTR unit and Immigration Bureau.
How the workflow runs end-to-end
For matters that touch multiple counters — Amphur District Office, DBD, DIP, BOI One Stop, or the Criminal Records Division of the Royal Thai Police — a dedicated runner sequences the visits in the correct legal order, so the client is not sent from one office to another chasing missing signatures.
Who this service is for
Foreign missions in Bangkok and international bodies on framework contracts receive a dedicated key-account manager, standardised invoicing on 30-day net terms, and monthly consolidated statements that meet their internal audit format — no bespoke translation project management on their side.
Coverage, fees, and turnaround
Same-day express is offered for filings tied to a flight, hearing, or academic deadline, subject to counter availability at MFA Chaeng Watthana and the destination embassy. The surcharge is quoted before work begins and is not applied retroactively.
Quality assurance and confidentiality
Every certified translation ships with a translator's declaration on our headed paper carrying the linguist's full name, credential number, and dated signature — the format immigration officers, university registrars, and consular staff are trained to accept without follow-up questions.
