Coming from the US, it's actually called "Visa Exempt" i.e. no Visa is required for 30 days.
That is completely different than "Visa on Arrival", that is for some other countries that are not eligible for "Visa Exempt". There are desks for "Visa on Arrival" before Immigration, however don't go there!
You can do the Retirement Visa, however there is a fair amount of money and requirements, but is doable. You can also apply to a Thai language school, however please register with one with the intent to actually attend classes. From my discussions with one school, the attendance requirements is not that difficult, and easily manageable. You can apply to a school after you arrive in Thailand, and they will manage all of the paperwork for you. They have 6 and 12 month programs available. Also some costs involved, but a lot less that the retirement visa, and a good option for your fist long term stay. Then if you still want to stay after this, can convert to the retirement visa.
Paulo Pattaya not understanding this. if you have retirement visa you have to have 800k deposited into a local bank. I did open an account with Bangkok Bank several months ago, just with Visa Exempt status, however all attempts to register online banking failed due to not having a Thai tax ID; even went to 2 banks and talked to them personally.
I was there only a few months ago. It was then recommended and suggested that ED was only being approved when already in Thailand. i.e. Language and Thai boxing. Visa exempt is only 30 days but can get 30 day extension while applying for ED visa, but you would want to start that right away and not wait until you have only a week left. A lot of scams but if you really plan to attend vs. just getting it for the purposes of staying I don't think you will have much of a problem.
Visas are not normal to have perks for duty free imports, although there are some countries with similar for citizenship conversions I recall.
They'd be concerned with some billionaire, or similar, importing a huge estate for basically nothing; then the following outcry from media and citizens.
Thai import taxes are rather steep and VAT is crazy high.
If you are under 50, don't think there is other "good" want to stay long-term however. 50 and over has the retirement visa "also not that great with 800K rotting in a Thai bank", but is still better than 1M paid to the Thai goverment. You avoid all the boarder runs, etc but are still subject to 90 day reports. I'm over 50 so would never consider this option, but also doubt I'd go for the 800K retirement either.
if you go to the Thaipass website it clearly shows you the answer, and yes it is required. If you really want to go, it will be necessary to actually go there and read all the requirements before applying,
under 30 days it's not ever a TM30, but is a different report that they report all foreigners that are staying at the hotel. This is what I used, and it has ALL residents listed, so they just crossed off the other tenants with a pen. Took my hotel all of 2 or 3 minutes to give me the form, and worked just fine.
