few people get letter fast, i still have lot of time but i apply now ... Only asking if letter issued now will be good for IO in may, end of april? Already did normal extension
Ranong very easy, boat to mynmar site for 700-1000thb, they make copies for you, give you 10usd banknote if you dont have, ranong IO very friendly and always without problem for me
yes this border .. 960thb for cross with minibus and myanmar stamp, easy ... Never had problem (knock knock :D ) even on airports, never asked for nothing
