Thai Visa Categories for Foreign Nationals — Full Reference
Thai visa policy is a mosaic of legacy Immigration Act categories, modern BOI and Ministry of Tourism regimes, and 2024–2025 innovations such as the Long-Term Resident (LTR) and Destination Thailand Visa (DTV). ILC covers every actionable category: Non-Immigrant B (employment), Non-B-A (representative office), Non-O (family, retirement), Non-O-A / O-X (long-stay retirement), Non-ED (study), Non-M (media), Non-R (religious), Smart Visa (T/S/I/E/O), LTR (four sub-categories including Wealthy Pensioner and Highly Skilled Professional), DTV, Elite Visa (Thailand Privilege), Marriage Extension, Retirement Extension, Permanent Residency (Section 41), and Naturalisation. Each category has an underlying statutory test — financial threshold, employer sponsorship, family relationship — that must be documented before submission or the application is refused at the counter with no refund.
