From a very recent post in a Hua hin group '' We both went to extend our 60 day visa at Blueport this afternoon..After waiting 2 hours and having all of the required paperwork we were advised to return to the immigration office 14 days before our visa expires.As our visa expires on 17th March not until the 3rd March..Hopefully this info will help others.'' Guess it depends how busy they are and what mood they are in 🙂
