it sounds like you are in a very similar situation to us. The LTR process requested that we produce my husband’s NOA + T1 General from last year. This did not have to be certified in any way. There was also no need to move any money at all into Thailand, and we didn’t have to show any money in our bank accounts. We did have to show health insurance valid for a year. We had that with IMG Global. Aside from our marriage certificate, I didn’t have to show anything else (as the dependant spouse).
use your income tax return from last year. It is not pension income but personal income that they are looking for. We do not have a pension yet we still received the visa on the strength of our income tax return.
yes, that is my understanding as well. It’s essentially having to apply all over again, although they said it would be a bit streamlined. Of course, since we’re so early in the LTR visa program, the renewing process hasn’t been created yet. Somehow, I have a feeling it will not be much different from what we just did, but with no payment.
