Can I extend my 60-day tourist visa in Thailand for an additional 30 days?

Yes, you can extend your 60-day tourist visa for an additional 30 days while you are in Thailand. This extension can be obtained by applying at the Immigration Office in your area. The process generally involves submitting your application along with a fee of 1900 baht. It's best to apply for the extension well before your current visa expires, typically within the last 30 days of your initial visa. Note that some nationalities may have different rules regarding extensions, so it's important to check your eligibility.
