do another. your second border run, than a 30days extension. In the meantime things have settled down and you can go to another place to get one more TV, next year 2 border run with extensio, so you baiscally covered up to beginn of may.
People following the various forums have noted that the closest Royal Thai Embassy Vientiane and Royal Thai Consulate Savannakhet have become very strict. This is not an Official Government Policy, this the the sole decsion by the people in charge of these places, so a Tourist Visa in KL, Penang, Yangon, Hanoi or HCMC is still OK.
You can have 3 visa exempt each 30 days from border (Russians unlimited) and they will give an ED. But they had a Tourist Visa with an extension, theyu were refused. If they had not extended that TR they would have been granted. Total madness.
