There a bus from Suvsrnabhumi to Hia Hin, that stops in Cha Am. There are 6 a day, costs 325 baht i guess. Its a big bus , safe to travelling, minibus its a bit dangerous as they drive fast.
, i have read on here many saying that. So i just tried to pass to you. I didn"t that a dependant could have it. And , this is a question, why a foreigner can have a dependant wife which is a foreigner too on his visa and bank account, but a thai wife can't give visa to her husband who shoukd have at least 400.000 in bank, Isn't strange?
Dont do that, why you do need to update, trough someone stranger , if you don't have special reason? If they loose your passbook, you know that you will have difficolt to deal with bank? Just an advice, by the way.
