Hey everyone, if you get a 30 day visa waiver (UK passport), what is the time frame for applying for the 30 day extension? (i.e. what is the latest and earliest you can apply?)
Thank you for your help
TLDR : Answer Summary
If you enter Thailand with a 30-day visa exemption as a UK passport holder, you can apply for a 30-day extension any time before your current stamp expires. Generally, most immigration offices accept applications when there are less than 30 days remaining; however, some offices may have more restrictive application windows. It's advised to check the specific policies of the local immigration office you plan to visit.
