Question regarding the required documents for a non-O retirement extension: I've read in some comments that a one-year detailed statement printed from your bank is required. Is this only for the 65k monthly income method, or also needed for the 800k proof of funds?

Last year I provided the original and a copy of all passbook pages, and it was accepted. (800k method, CW office)

I need to renew my extension of stay based upon retirement in 8 weeks time. My question is can I renew based upon the 800k method and in 2025 use the income letter method (my Embassy does issue income letters).

Basically I want to spend my money. Will Immigration backcheck to see if I left the required amount in my bank balance for the 2024 renewal. (800K 3 months after and draw down to min 400k)

Thank you
