You have to do a 3 months non-o visa, you show this visa at the bank and can open an account. Deposit your 800, after 2 months you can request a retirement extension at immigration
it's because of the confused results of my own research that I am asking here. It would be nice if someone who knows would write something like a FAQ on the group. I am not asking for me because it's already 12 years I am here with the yearly extension.
