What are the requirements for extending the Thailand 10 Year LTR visa after the first 5 years?

I am expecting that I will have to reapply in full in 5 years. I plan on keeping copies of my tax returns and insurance certificates for the next 5 years in case they ask whether I continued to meet the requirements.

I had an OA for six years. You have to show that you met the financial requirements throughout the year, for example with a yearlong bank statement, in order to qualify for a subsequent extension. I am assuming the same logic will apply to the 2nd 5 years of my LTR.

I didn’t ask the BOI directly what they would do in five years because I assumed that they don’t know exactly themselves. I did ask if they would check about my insurance coverage each year and they said they would not. My pension won’t change so I didn’t have to ask about that.

No it's not an automatic additional 5 years, or they would just give you the 10 years at the beginning.

You need to qualify again after 5 years. Ask the BOI what the process will be as no one can answer your question because no one has done it. The BOI probably doesn't even know yet.

I was told I have to do the entire application again but I just won't have to pay.
