Hi Group, for Retirement visa renewal if I am using Embassy letter as proof of income do I still need to provide bank statements and update bankbook etc on renewal date?

Secondly does anyone has any tips or advice on visiting the Nonthaburi Immigration Office? I tried getting a check list there but they don't have one and all they said was same as last year but i dealt with another IO last year. I am wondering what their pictures requirement is specifically.

Finally is making an online appointment useful there? I will make one in any case 😬

TIA 🙏🏻
