So, I'm guessing I can extend my 30 day visa exemption for a further 30 days? Technically, exemption is not a visa.
TLDR : Answer Summary
Yes, you can extend your 30-day visa exemption for an additional 30 days, which is considered an 'extension of stay.' This process is handled by immigration, and it costs 1900 baht along with the requirement of two passport-sized photos.
