I did this. I am one of thousands of people who live at the KOA in Spearfish. The locals that actually live there don’t like us voting in their local elections tho.
set yourself up with a South Dakota residency. It’s easy. Spend 1 night and get a Personal Mailbox from one of a few companies doing this. Go to the DMV and get a drivers license. You will then be an official resident of South Dakota. No state income tax.
The mailbox company will let you know when you receive mail. Then you decide to open and scan, shred or have forwarded somewhere. $150 a year plus any added expenses over the monthly mail allowance.
you might want to check if you really still have that bank account. Many have been closed and frozen. Go thru this groups posts for examples of closures.
Immigration itself doesn’t ask for the onward travel as often as the airlines. Immigration officials in many countries use the airlines as de facto immigration agents. They can be fined by the various countries for allowing you to enter without an onward ticket. Most people never deal with this because they have purchased round trip tickets and the airline already knows about that travel so they don’t ask.
that’s what you are supposed to do. Attend a course the entire time of your stay. Yes people have been booted out because they have not been attending.
1 reason is you can buy the baht inside the Revolut account at any sort of bounce up in exchange rate. Without having to run to the atm when you see the rate you are looking for.
I personally only use the Revolut card with Apple Pay. Since it pulls baht out of my account. When I make a purchase I know exactly what is being withdrawn without trying to figure out the conversion I am getting at time of purchase.
