I call that BS. It's the UK Embassy which decides if she is safe to go. On a valid visa, she won't be denied entry. She could however be asked to show funds in CASH and a credit card. Never heard of any Thai woman turned down at the UK border when she had a valid visa
it can be tricky to pay for an entry. There are "VIP-entry agencies" who meet you not at land borders but at airports and guide you through "arrival channels". I however do not recommend their continued use, if your stamp history is extensive. You need to get a visa that is fit for your purpose. Non-Imm-ED visa only work for like 2 to 3 years, you need to prove you attended school, and after that you will be scrutinized on every entry. DTV "soft power" is a good way to go, it still amazes me that they pulled out a visa on which you can get 5-years, by paying & joining a cooking class or a Muay Thai Camp. You need to prove 500,000 THB on your bank account (some embassies ask for a 3-months proof). Elite Privilege is another safe way but rather very costly
By the way, there is nothing such as a "back list". I guess it was just a typo from your side. There however is a "blacklist"
That would be a yearlong prohibition of entry.
Only people that have been arrested on an overstay, or those who have broken the law, like having worked in Thailand without a work permit, have been court tried and prosecuted, can be "blacklisted" from Thailand.
People who receive a "flagging" in the system haven't committed any crimes - they just have "overused" the visa-exempt entry, and it can also happen to those who misuse consecutive back-to-back tourist visa for a longstay
. A denial of entry will get recorded in the Immigration Central Computer, but it does not automatically result in a "blacklisting". It however results in what we call "flagging".
A blacklisting would mean that you are banned from entering Thailand for a specific period of time.
However, we were talking about a denial of entry at the border, and the reason given was “overuse” of visa-exempt entries. It means, that after a certain period having spent outside of Thailand, you can enter again, if you hold the correct visa for your specific purpose.
And in other words, if you get pulled aside and questioned, and they can decide to allow entry, however if they do so, it gets accompanied with a warning that for the next time you need a proper visa for the purpose of your stay. In this case, you will get "flagged" in the Immigration Central Computer.
Each time an Immigration official scans your passport, your personal page will come up, and your record will show that you have been warned.
We call this "getting flagged". This is what your "personal page" will look alike, and in the lower left corner there is a box into which your "flagging" will be noted!
Oh, what an Immigration officer is free to decide, is actually regulated in the "Immigration Act". Just read through it. . . . a border official is free to decide if he/she allows you to enter or not. . . . . . Here's the law(s):
it is called TDAC, not "e-visa card". It is a digital arrival card, like the old TM6 paper arrival and departure card that was discontinued a few years ago
In case you then have to buy a one way return ticket, no, that kind of ticket would be the most expensive ticket class. It could come cheaper to buy a one-way ticket out of Thailand with a budget carrier. You need to compare
the Non-Imm visa becomes invalid upon entering Thailand. . . . . after this you live in Thailand on an "extended stay permit" and not on a non-existing visa
