Can I extend my 60 day tourist visa 20-25 days before it expires, or do I have to wait for a shorter period before it expires?
Is there a rule on how many days before expiration I can do this?
Thanks.
TLDR : Answer Summary
You can generally apply for an extension of your 60-day tourist visa depending on the location in Thailand. In most offices, you must have 30 days or less remaining on your visa to apply for an extension. However, in major cities like Bangkok and Chiang Mai, you can apply when you have up to 45 days left on your visa. In places like Jomtien/Pattaya and Koh Samui, you must be within your last week before applying.
