Good morning. I’m coming from Australia mid July. I’ve got my 60day visa. My flight is in 60 days but I want apply for a 30day extension as soon as allowed so I can change my flight to 90 day stay. I know it’s a visit to Immigration and the form to fill out along with 1900 baht. What’s the earliest I can ask for the extension in Bangkok immigration?
Thank you so much for this site.
