I have a multiple entry 12 month retirement visa from Mumbai until March 2025. Can I extend this in Thailand or do I need to reapply outside of Thailand every year , 30 days before expiration?
TLDR : Answer Summary
You can extend your multiple entry 12-month retirement visa within Thailand without needing to reapply outside. For a Non-OA visa, you can stay for up to two years by leaving and re-entering before the visa expires, while for a regular Non-O visa with multiple entries, you can also extend your stay by leaving and re-entering, which allows for an additional 90 days.
