Do I need to re-enter Thailand before my METV visa's 60-day expiration for an extension?

To extend your METV visa, you need to re-enter Thailand before the 'enter before' date on your visa sticker. If you re-enter after this date, you may still receive 60 days as long as you enter before the expiration of your last 60 days. Additionally, you can apply for a 30-day extension at an Immigration office before your current visa expires for a fee of 1,900 THB.
