when I did mine I walked in told them I needed to open an account because I was carrying lots of cash to buy a condo and they opened it immediately I didn’t even need tm30 or residency but I know things are harder now than it was.
they looked for my visa last night when i arrived, i had to show them which one as i have a few glued into my passport, then i got taken away to the fast track area as they didnt understand what the OX visa was and had to get senior Immigration officer to explain what stamp to give me. Some are not very switched so i always check they have stamped me into until 2027
