Can I extend my 60-day tourist visa in Thailand for an additional 30 days?

Yes, you can extend a 60-day tourist visa in Thailand for an additional 30 days for a fee of 1,900 THB. The extension should be done at the Chaengwattana government complex in Bangkok, specifically at Counter J. When applying for the extension, be prepared with copies of your passport's photo page, visa page, entry stamp, a passport photo, and the fee. The extension will be valid for 30 days from the date of your application, not from the last date of your original stamp.
