Just remember that you will also have to pay tax on anything you remit to Thailand 🇹đź‡- if you spend 180 days or more here in a calendar year. IT DOES NOT MATTER IF YOU HAVE ALREADY PAID TAX ON SAID FUNDS IN THE UK.
Just to let you know…
The new tax rules came into effect 1 January 2024.
Hi there, it is easy these days, took me all of one week. There is no medical requirements for a Non O, nor insurance requirements. Perhaps you were thinking of a Non OA?
Get a non O visa (90 days) in your home country. Open a Thai bank account when you arrive - no issue if you have a non O visa. Go to your local IO to find out their specific requirements for a 12 month extension and then apply.
