My non-immigration visa expires on 10 November and I would like to extend my visa. I have a letter from my embassy to support this. Would you know of any other documents that I need to provide and can you confirm where do I get this done ?
TLDR : Answer Summary
To extend your non-immigration visa expiring on November 10, you will need a letter from your embassy confirming your inability to travel, which you already possess. It is advisable to visit your local immigration office to find out if any additional documents are required, as the rules may vary by office. Some immigration offices might offer extensions without the embassy letter, charging around 1,900 baht for a 60-day extension. Since your visa is not expired yet, you may qualify for these options and potentially benefit from new extension programs if they are initiated by your appointment time.
