Do retiree visas require health insurance?

Both Non‑Immigrant O‑A (1‑year retirement) and O‑X (long‑stay retirement) require proof of valid health insurance covering the entire requested stay. Official minimums are 400,000 THB for inpatient care and 40,000 THB for outpatient care per policy year. Policies may be issued by Thai or foreign insurers but must meet these amounts and be documented in English (policy copy and insurer certificate). Present the insurance together with the visa application and medical/financial documents required for each visa. Requirements are set and enforced by Thai embassies/consulates and immigration; check the specific embassy/consulate processing your application for any additional local requirements or temporary COVID‑era rules. See guidance from Thai embassies/consulates and the Ministry of Foreign Affairs for official details.
