Thailand Transit Visa — Requirements, Cost, Processing Time

The Thailand Transit Visa (Category TS) is specifically designed for international travellers who need to pass through the Kingdom on their way to a third country. While many passengers remain in the 'sterile' international zone of the airport and may not require a visa, those with long layovers, separate flight bookings that require baggage re-checks, or those switching between Suvarnabhumi and Don Mueang airports will typically need to clear immigration. This visa is also used for specific categories of visitors, including crew members of conveyances arriving at Thai ports and athletes participating in sporting events. Unlike the visa-on-arrival scheme available to certain nationalities, the Transit Visa usually requires an application through a Thai diplomatic mission abroad prior to your journey. Please note that visa policies are subject to frequent change. All applicants should verify current requirements with their local Royal Thai Embassy or Consulate-General before making travel arrangements or submitting an application.

How to apply, step by step

  1. 1

    Determine Eligibility

    Determine if your nationality is visa-exempt or if your layover requires you to pass through Thai immigration.

  2. 2

    Complete Application Form

    Download and complete the official application form from your local Thai Embassy's website. Ensure all details match your passport.

  3. 3

    Prepare Documentation

    Collect all required documents, including your passport, photographs, onward tickets, and proof of funds.

  4. 4

    Book an Appointment

    Book an appointment at the nearest Thai Embassy or Consulate. Some locations may require walk-ins or use third-party services like VFS Global.

  5. 5

    Submit and Pay

    Attend your appointment to submit your documents and pay the non-refundable application fee in the local currency.

  6. 6

    Wait for Processing

    Wait for the consulate to process your application. You may be asked to provide additional information during this period.

  7. 7

    Collect Your Passport

    Once approved, collect your passport with the visa sticker. Check that the number of entries and stay duration are correct.

Tips to avoid refusal

  • Apply at least 3-4 weeks before your flight to account for any unexpected consulate delays.
  • Ensure your flight tickets are 'confirmed'—reservations without a ticket number may be rejected.
  • If you have a self-transfer (separate tickets), you will almost certainly need to clear immigration.
  • Double-check if you are changing airports; transfers between BKK and DMK require a visa or exemption.
  • Check your passport's expiration date; Thai authorities are strict about the 6-month validity rule.
  • Keep a digital and physical copy of your visa and onward tickets during your transit.
