Non-Immigrant O-A (Long Stay)
Thailand's O-A retirement visa is open from age 50 and requires health cover of at least 3,000,000 THB (USD 100,000) per policy year, from a Thai insurer on the TGIA long-stay list or a foreign insurer that can complete the Foreign Insurance Certificate.
In its favour: Renewable indefinitely in-country once established, with no exit requirement beyond 90-day reporting.
Watch for: The insurance requirement becomes expensive or uninsurable with age and pre-existing conditions, and is the single most common reason applications fail.
