How to switch from Non-B to LTR

Why switch from Non-B to LTR

• 10-year visa instead of annual extensions
• Tax exemption on foreign-source income (Royal Decree 743)
• Annual report instead of 90-day reports
• Family included (spouse + 4 dependents)
• Free Digital Work Permit replacing your traditional work permit

Eligibility check first

Run our eligibility checker. You need:

• Highly-Skilled Professional: BOI-promoted target industry + $80k+/yr (or $40k + masters/5+yr exp)
• Work-from-Thailand Professional: $80k+/yr + employer is public-listed or revenue $150M+

Step-by-step transition

1. Apply via BOI online portal (ltr.boi.go.th) while still on Non-B. No need to leave Thailand.
2. Upload qualification docs — employment contract, payslips, education certificates, employer info.
3. BOI review takes 4-12 weeks. They may request supplementary docs.
4. Approval letter issued. Pay ฿50,000 visa fee.
5. Choose your visa stamping method: at Chaeng Wattana One Stop Service Center in Bangkok (recommended), or via Thai embassy abroad on next exit/re-entry.
6. Get Digital Work Permit at the same One Stop Center, free. Bring your old Non-B work permit blue book to surrender (it gets cancelled).
7. Notify your employer — your work permit is now Digital Work Permit, not the old paper book.

Timing the transition

Best timing: while your Non-B has 6+ months remaining. The BOI process takes 1-3 months. You don\'t want to be in expiry crunch.

Your Non-B and work permit remain valid throughout the LTR application. Once LTR is granted, the Non-B becomes redundant.
