Did my extension to my 45 day visa exemption today(still over a month left on it). Went to LAKSI IT Mall. Arrived 9:20. Went next door to get photo copies and passport photos - 204 baht. Next to desk to get queue number. Needed 2 documents besides the TM7, a STM2(request for extension and reason - same as second half of TM7) and a 3rd one that you declare you understand penalties for overstay. All 3 documents can be obtained there if you do not have them. Documents checked and received queue # (I was #39) and there were about 25 ppl waiting outside the office. They called 5 ppl at a time into the office by #, checked documents and paid the 1900 baht. Back outside to wait by 10AM. Waited for 1/2 hour and they call to pick up completed passport by number. Done by 10:30AM. Be sure to have hotel info, room # and a ph # as these were asked for 2 times even though I had already put them on TM7. Best to arrive early as there were about 75 ppl waiting by the time I left at 10:30. Good luck to all.
