The Thai consulate in Penang will now only issue 3 tourist visas back to back, on your third Thai tourist visa it will state that you cannot apply for another tourist visa in Penang, what you can do though is go to any other country, ie Singapore, Laos, Cambodia and get a tourist visa for Thailand there, or just do a border run and come in on a 30 day stamp, after this you can then do another 3 visa runs to Penang to get your Thailand tourist visas again.
