WISE only transfers into Thailand, not out of Thailand. That's what Dee-Money is for. Or you take out the Thai Baht and bring 'em to a money changer like SiamExchange (north of the MBK Center) or the SuperRich head office. There you will be able to exchange them back into US Dollars and you are allowed to take 'em out of Thailand
if you hold high savings in your home country, and can prove it, Thailand will not tax a single Satang of it. Thailand only intends to tax INCOME. Savings are NOT an income
I use WISE. The limit of a single transfer is 2 million Thai Baht (actually it should be 1.999.000.- THB) into your Thai bank account. But only THREE Thai banks will accept a transfer higher than 50,000.- Baht. These are Kasikorn, Bangkok Bank and Siam Bank PLC . . . .
"Multiple Re-entry Permit - can I get this at any airport e.g. Hua Hin?" . . . . . . . . . . . . . . . . . normally only at international airports (Suvarnabhumi or DMK or U-Tapao or Chiang Mai) Hua hin is not yet an international airport . . . . . . . . . . . . . . . . . . . . . . . . . better you buy a re-entry permit on Immigration, as soon as you got the "Extension of Stay" stamped in your passport
yes, it is always good when you enter Thailand coming from Cambodia, without a visa for Thailand, if you can show 20,000.- THB/ 40.000.- THB for a family, in cash (or equivalent in another currency) and proof of accomodation for the next 2 days and a proof of onward travel out of Thailand within the 30 days you will get stamped into Thailand . . .you CAN be asked or you won't be asked. It is up to the discretion of the Immigration officer. I would not worry too much. You will be fine, nobody will harass you at the border as you are a "normal" tourist who travels South East Asia with her son
you can use Ban Pakkad or Ban Laem easily to get back into Thailand. Or if you are far up north Cambodia, cross at Chong Chom. Easy and friendly border. Poipet is treacherous for same-day border bouncers, but since you have stayed in Cambodia for a holiday, you needn't worry about not getting back to Thailand
he would most probably not have succeeded if he did a border bounce by himself without a visa. Trying to enter Thailand visa-exempt in Poipet on yourself is not recommended. You should pay a "Visa Run Agency" to take you there and back. They grease the wheels at the border. . . . in case he re-entered on a multi entry visa, then no wonder it was kinda streamlined, because this is what these visa-categories are created for
