Thursday I did a border hop in order to void my Non OA. The hop was uneventful and amazing easy to do (thanks to the help from the experts on this forum). The next day I had an appointment at CM immigration to obtain a Non O visa using a TM87. I had all the required forms and bank documents, etc. So I foolishly thought that for the "first time" I would complete the transaction without delay. But the IO said the TM87 was the wrong form. A TM7 was the correct form. I pointed out that I entered visa exempt. So I was using the TM87 to obtain a Non O visa. He said no visa is needed for a long term retirement stay. I only had to extend the "expiration of stay date" stamped in my passport. So needed a TM7.
Knowing that one must respect an IO's authority, I politely asked for all my forms to be returned to me.
I have an appointment on 5 January to try again.
Is the IO correct? No need for any visa. Just meet the financial requirements. And use a TM7 annually
to stay retired in Thailand until I'm dead.
