For 5, its a certificate of residency, i needed my lease, landlord passport picture ans picture of their bluebook, if i remember correct, it was long time ago, since then i have had it in my passport where they put it
I would advice to put less than 180, i did 179. No idea why they ask it. Maybe if you put 40 they grant you TR instead becausw its enough? 😅 who knows, this is thailand
You dont need a ticket, but they ask for planned dates of arrival and departure. If you plan 6months ahead, dont expect them to handle your application for a long time
i have many friends who have lived here for tens of years, telling me the same. And its not only for border runs, but also if you want to actually go to cambodia by car. Also said to be very busy border
