Assume a 60 day Tourist Visa and I stay 20 days in a Bangkok hotel, 10 days in private Bangkok residence (say no TM30 req'd in BKK) then 20 days in Pattaya (50 days) and then apply for 30 day extension in Jomtien. Surely Jomtien Immigration will fine me for the TM30 gap in my national file by saying I probably was in Pattaya for those earlier 10 days??? (I cannot prove them wrong if Bangkok Immigration say dont bother us ie no evidence).
