Just been to Jomtien, Pattaya immigration for 90 day report, i know you can do it online, but it was easy to walk in hand passport, get number, go and have a beer, walk back, pick up passport.
Today was different, need copy passport, copy visa, copy last renewal, plus fill out a 90 day form, after that same process as before.
Understand it changed today, 18 Oct.
