Successfully extended my 30 day visa on arrival at Jomtien immigration yesterday with 11 days left on admitted till date of 2/17.
When handing my passport over I asked how far in advance I could extend & was told a few days only. After finishing asked at the check in counter & was told that now as the are busy can only extend 1 or 2 days before expiration date.
Just wanted to post in case someone needs to know about extension of stay in Jomtien.
