2. How NAATI Thailand Thai-visa service works
1. Eligibility check (free) — we review your nationality, age, financials, current visa status, and goals to recommend the most suitable visa category. Sometimes Smart Visa or LTR is better than Non-B + WP.
2. Document collection from home country — police clearance, marriage cert, birth cert, education docs — translated + MFA legalised (Thai Apostille takes effect 28 Feb 2027; until then the embassy step may still apply).
3. Document collection in Thailand — Thai spouse ID/house book, employer documents, BOI certificate, school enrollment, bank statements.
4. Bank deposit / financial structuring (Retirement, Marriage) — guidance on the quoted on request / 800,000 / monthly income rules and timing requirements.
5. Initial Non-Immigrant visa application — usually at Thai Embassy in your home country or neighbouring (Vientiane, Penang, Kuala Lumpur, Phnom Penh).
6. In-Thailand processing — extension at Immigration Bureau Chaeng Watthana or provincial office; 90-day report; re-entry permit.
7. Work Permit (if applicable) — Ministry of Labour application, BOI fast-track if eligible.

4. Common pitfalls and how we prevent them
Pitfall 1: Bank deposit not seasoned 2 months before extension — Marriage and Retirement extensions require deposit history. We plan timing precisely.
Pitfall 2: Wrong work permit job description — Ministry of Labour job titles are restrictive. We pre-clear the job description with both Immigration and Labour to prevent rejection.
Pitfall 3: Missing 90-day report — overstay penalty price on request + immigration record. We set automated reminders.
Pitfall 4: Re-entry permit expired during overseas trip — visa cancelled. We handle multi-entry re-entry permits for clients who travel.
Pitfall 5: Wrong embassy for initial Non-Immigrant visa — some embassies only accept residents. We recommend the right embassy (often Vientiane, Penang, or Phnom Penh).
