Myanmar. I know why now. As soon as I got passport, I didn't go to Thai embassy at Yangon to get 30 days Tourist visa. I just came by flight . For Myanmar, we get 14 days free visa. So on that day 2nd May, I went to Chumpon immigration office and extended 7days more (TM 7). I had to pay 1900 as well. Actually, I got a job here so I have to apply Non B Visa , for that I need 14 days to be in Thailand cuz I need to wait for all the docs from school, labour ministry and so on.. Plus school isn't open yet. They can't be done within 7 days of my stay😥.
So sad for me😥 my tourist visa date was (19 April -2nd May) so on 1st of May i took bus from Hatyai to Ranong but I was rejected to cross the border. Ranong Immigration Officer said I can only use flight back to Myanmar 😥
