Advice plz. ( SETV)
I am from Bhutan. I have already done 2 times border runs to Vientiane this year (2017). So far I haven't got any warnings on my passport ( except one day overstay seal at local immigration in Bangkok, which I forgot) although I did several times border runs to Vientiane and Savanakhet. I would like to still extend my stay in Thailand for few more months.
What would be my options? Plz. advice your experience and ideas. Thank you in advance.
