on the data page on the bottom right it says USA. Above that it says authority. List what it says below "authority", usually United States state department.
Anonymous participant just leave and return. You have a five year visa. You only run into problems if you try to extend it inside Thailand. Just border bounce for five years, and you are fine. They only check things if you try to extend it.
for the first time you need a notarized wage statement from the UK embassy, but unfortunately they no longer issues them, so the first year you need the bt400,000 in the bank.
Are you the mother of the children? If not you might need to show you adopted them to have a familial tie to include them under your visa. Your husband won't be a problem. They kids can come in on a simple visa exemption, and stay, as until they are 15 there is no overstay fine for them.
So far you have a pattern of being a tourist. Keep that pattern going by visiting a different country for a week, or two, then returning, and not getting the 30 day extensions. There are lots of countries around, and close to, Thailand that you can do it for years. Lots of tourists base out of Thailand, Bangkok specifically, when visiting other countries in South East Asia. Keep the pattern of a tourist, not someone trying to stay here long term as a tourist.
keep in mind that it is much better to apply for the type O visa before you come to Thailand, as once you get here you will need a Thai bank account to meet the financial needs for your one year extension, a d that is getting to be almost impossible on any tourist visa. By having the 90 day retirement visa when you get here makes it simply a question of what bank, or banks, you want to open an account at. Bangkok Bang, and Kasikorn bank are the most friendly to expats, with Bangkok Bank being the most popular. I personally have 3 accounts with Bangkok Bank, and one with Kasikorn bank. In the US the best is to have a brokerage account with Charles Schwab, and get the account that offers 4 free SWIFT international transfers a month, if you can afford it. That together with a FCD account, foreign currency deposit account, at Bangkok Bank, is the cheapest way to regularly transfer money into Thailand, with a maximum fee of just bt500 no matter how much you transfer. As an example you can transfer in US$1million and the fee is just bt500. Then you can change dollars in your FCD account into baht at your convenience, and at the TT exchange rate with no extra fees. These are just things to keep in mind if this will be your new home.
If you are not married to her you need a legal business, and a work permit, to be legal. The business itself isn't that expensive to set up, but the work permit is, with a required minimum of bt2million in registered capital in the business for each work permit, and four Thai employees, unless you are American, in which case you can set up under the treaty of Amity, but still need the registered capital amount.
what would you call it if he flew in, thinking that would be different, and was denied entry? Wouldn't he also be deported, as he can't stay in the airport?
