The O-A Long Stay visa — and its 3-million-baht insurance trap (2026)

By Eksiam Chaisorn, Thai legal expert · Member of the Thai Bar Association · Updated July 2026

The O-A is the "official" retirement visa most embassies point you to. It works — but it carries a condition that ages badly. Read this before applying from your home country.

O-A requirements (applied at a Thai embassy in your country of nationality/residence)

Why lawyers hesitate to recommend it

The insurance requirement doesn't end when the visa does. Every in-country extension of an O-A stay requires proof of compliant insurance — forever. Premiums for a 75-year-old on a ฿3M policy commonly run ฿100,000–250,000+ per year, insurers can decline renewal after a claim, and most Thai insurers stop writing new policies at 70–75. We regularly meet O-A holders in their late 70s facing premiums larger than their rent.

By contrast, the Non-Immigrant O route has the same financial requirements and no insurance mandate at most immigration offices — you remain free to buy insurance because it's wise, not because a rule forces you into whatever policy an approved insurer offers. Compare: health insurance for retirees.
