Thailand Non-Immigrant Visa

The non-immigrant visa is for travellers coming to Thailand for a specific purpose beyond tourism. According to the Ministry of Foreign Affairs it allows a stay of up to 90 days per entry. It has several categories, including “B” (business), “B-A” (business-approved), “IB” (investment/business), and “O-A” (long-stay, for applicants aged 50 and over who will not take up employment). Applications can be made through the official Thai eVisa system. The exact category, conditions and requirements depend on your purpose — confirm with the official Ministry of Foreign Affairs guidance.
