Hi, if I come back by the night bus from Udon Thani to Chiang Mai, that night I spend is not going to be a problem once I come from Vientiane, right? Last year nothing happened, but not sure how "picky" are this year. Another question. My friend will do the TM30 online because I will stay in her place. I´m ok with an invitation letter a copy of her ID and copy of the blue book with the TM47 filled once I go to do my duties? It´s for a Non ED Visa. Thanks!
