Short meetings within 30 days can also be made under the visa exemption, but the Non-B gives longer and repeated stays.

Fee and payment

The visa fee is set by the Thai embassy or consulate handling the application, shown in the e-Visa system and normally paid online when you submit it; a few missions, such as Islamabad, take payment at the embassy. It is not refunded in any case, including refusals caused by wrong names or e-mail addresses, so check your data before paying.

On arrival and during your stay

Your permitted stay is stamped by the immigration officer on arrival. Foreigners staying in Thailand for more than 90 days must report their address to the Immigration Bureau every 90 days, except for categories with special rules such as LTR holders, who report once a year. Extensions of stay are handled by Immigration Bureau offices inside Thailand.

How to apply, step by step

  1. Ask your Thai partner for an invitation letter and prepare three months of bank statements.
  2. Create an account on thaievisa.go.th (one account can hold up to 10 applications) and choose the country where you are currently located; the Thai embassy or consulate responsible for it will process the application.
  3. Select the visa type and purpose, fill in the form and upload the listed documents as clear scans.
  4. Pay the visa fee shown by the system; it is not refunded if the visa is refused or your details are wrong.
  5. Wait for the decision within the processing time of the mission handling your application; answer any request to correct or add documents.
  6. Print the approval e-mail and show it to the airline and Thai immigration on arrival.
