I was with an agent in Pattaya,they said they could do the retirement visa if you already had a bank account. Unable to open an account for anyone. What agent is still doing bank accounts I am sure people on here would want to know.?
Your biggest problem at the moment is opening a bank account it is impossible as the banks have tighten up on scam gang bank accounts,was in an agents office 1 week ago she said banks are not allowing new accounts to be opened.
Apply for a 60 day tourist visa the once in Thailand get a retirement visa this will be the easiest and cheapest way if you want to have a longer time in Thailand.
