So Im planning to travel to Udon Thani. I am currently in Pattaya. I read reviews of the immigration office that most places there don't/refuse to report TM-30 which makes it challenging to get an extension? Is this review true about the city? If so, what can I do to prevent wasting time? Can I file? I'm only about 13 days into my 45 day visa, is it possible to file like tomorrow in Pattaya then head to Udon?
