There are rumours going round that all entries on land borders to Thailand if you don't have a visa and are going for your normal 30 visa exempt stamp they are now only giving 15 days, as far as all the visa run companies in Pattaya go this is not true and they have heard nothing at all about it, a friend went on Monday and got his normal 30 day stamp, they also labelled it as his second one in the 180 day period as is per normal.
I have just spoken to another one of the companies this evening that do daily runs to Cambodia and they haven't heard of this either.
