We are hoping to retire to Thailand in April 2023. Am I correct in thinking we need to apply for a 90 day visa here in the UK and then apply for our retirement visas once we are in Thailand and have set up a bank account with the relevant funds in place? Also would we need to purchase return tickets from the UK, even though we wont be coming back (or at least for sometime). I am sure I have read it is not possible to buy a one way ticket.
