About Upgrading Your Thai Visa with SiamConsult

Upgrading (converting) your visa means changing your permission of stay inside Thailand to match your real purpose — work, family, study, retirement, or long-term residence.
With SiamConsult, your upgrade is mapped clearly, documents are prepared bilingually, and submissions are coordinated directly with Thai Immigration and the relevant authorities (MOE, BOI/OSSC, LTR units).

What an Upgrade Involves

  • Eligibility review: We assess your current status, remaining days, and best upgrade path.
  • Document strategy: We prepare checklists, translate/support papers, and fix gaps before submission.
  • Official coordination: We liaise with Immigration and — where required — MOE (ED), BOI/OSSC (SMART), or LTR units.
  • Submission & tracking: We schedule appointments, submit, follow up, and guide you through to approval.
  • After-care: We set reminders for 90-day reports, renewals, and re-entry permits for travel.

Typical Upgrade Paths We Handle

  • Tourist/Exemption → Non-B (Business/Work): For employment or teaching roles; includes company paperwork and timing for Work Permit.
  • Tourist/Exemption → Non-O (Marriage/Family): For spouses/parents of Thai nationals or dependents of valid visa holders.
  • Tourist/Exemption → ED (Education): For language, private school, technical, or sport programs approved by the MOE.
  • Tourist/Other → LTR (Long-Term Resident): For qualified professionals, retirees, or investors meeting LTR criteria.
  • Tourist/Other → SMART (T/I/E/S): For BOI-qualified talent, investors, executives, and startups.
  • Non-O (Retirement/Marriage) ↔ Non-B/ED: Switching categories as life or work circumstances change.

Real-World Examples

  • Teacher in Krabi: Arrived on Tourist status; upgraded to Non-B with school contract, company docs, and coordinated Work Permit issuance.
  • Family in Phuket: Tourist couple married in Thailand; upgraded the foreign spouse to Non-O (Marriage) with marriage registration and financial proof.
  • Student in Ao Nang: Short-term visitor accepted by a language institute; upgraded to ED Visa using MOE-approved enrollment and attendance plan.
  • Professional in Phuket: Senior executive at a BOI company; converted to SMART “E” after BOI endorsement through OSSC, no separate work permit needed.
  • Retiree in Phang Nga: Visitor meeting age and funds criteria; upgraded to Non-O Retirement with bank balance verification and local address compliance.

Why Upgrade with SiamConsult

  • One point of contact: Clear guidance from first assessment to visa stamp.
  • Bilingual precision: English–Thai checklists, forms, and certified templates.
  • Authority liaison: Immigration, MOE, BOI/OSSC, and LTR coordination handled for you.
  • Compliance-first: Correct timing, TM30, re-entry permits, and 90-day reporting.
  • Regional coverage: Krabi, Phuket, Ao Nang, Koh Lanta, Phi Phi, and Phang Nga.
Many upgrades can be done inside Thailand if timing and documentation are correct. SiamConsult reviews your remaining days, current status, and target visa to choose the safest path (in-country vs. embassy).
Tourist/Exemption → Non-B (work/teaching), → Non-O (marriage/family/retirement), → ED (language/private/technical/sports), or → LTR/SMART for eligible professionals and investors. SiamConsult maps options, pros/cons, and timelines.
Valid passport and stay, purpose evidence (job offer & company set for Non-B; marriage/custody for Non-O; MOE docs for ED; BOI/LTR qualification for SMART/LTR), financial proof if required, TM30, photos, and forms. SiamConsult compiles, translates, and arranges everything approval-ready
Varies by category and office workload—well-prepared cases often complete within a few weeks. SiamConsult sequences steps, books appointments, and tracks progress to keep your status continuous.
No. Don’t work or receive income until the new visa (and work permit, if applicable) is issued. SiamConsult synchronizes your Non-B upgrade with Labour filings so you can start legally.
Short passport validity can limit approval length; travel mid-process may cancel your application without a re-entry permit. SiamConsult advises on passport renewal timing and secures re-entry permits to protect your status.
Act immediately. Overstay complicates upgrades and can trigger fines/bans. SiamConsult prioritizes urgent cases, advises corrective steps, and coordinates a compliant path forward with Immigration.
Yes. Dependents can convert to Non-O (Family/Dependent) linked to your new status (Non-B, LTR, SMART, ED, etc.). SiamConsult prepares family files together for synchronized approvals and renewals.

You’ll pay government fees (Immigration/Embassy, extensions, re-entry permits) and, if relevant, MOE/BOI/LTR/Labour filings, plus professional services. SiamConsult provides an itemized quote upfront—full transparency on totals before you proceed.

I applied for a Non-B Visa and Work Permit through SiamConsult, and the process was smooth from start to finish. They explained every step clearly and handled all the paperwork with Immigration and the Labour Office. I now work legally in Thailand without stress. Highly recommended!”
