Will be extending my non-b visa for 12 months in January after having been here 15 months. Advice requested regarding cost of this. My accountant at work says it is 15,000 baht paid to immigration office. Wanting confirmation before handing over any money.
TLDR : Answer Summary
The cost for extending a Non-B visa (Extension of Stay) in Thailand is confirmed by various community members to be 1,900 baht, despite some misinformation suggesting it could be as high as 15,000 baht. It is advised to confirm requirements directly at the Immigration Office.
