How can I extend my 30-day visa exemption to 60 days in Surat Thani, and how does the extension date work?

To extend your 30-day visa exemption to 60 days in Surat Thani, you can apply for a 30-day extension at a local Thai Immigration office. The new date will be added to your current visa's expiration date, meaning you will not lose days if you apply before your current expiration on March 6th. The standard fee for the extension is 1900 Thai baht.
