Can You Extend a Visa After Overstaying in Thailand?

If a tourist from Canada overstays their 30-day visa exemption by a few days in Thailand, they can still qualify for a standard 30-day extension. However, they must pay a fine of 500 baht for each day of the overstay. The extension will only be valid starting from the date their original visa stamp expired, meaning the days lost to overstay will be deducted from the new extension period.
