I recently moved into the UK on a Skilled Worker Visa and have National Insurance number. It will be a few months before I'm officially a UK tax resident. Do I have to wait till I'm a UK tax resident before I can open an ISA? How about pension contributions? Can I open a SIPP account before April 5 2024?

I am considering moving to the UK in April 2024 though a company transfer and I have RSUs previously granted by my US employer which will continue to vest every quarter while I'm a tax resident in the UK. I have some non-salary income in my home country and intend to apply remittance based taxation for this income. Will this also apply for RSUs vesting in the US company (assuming I don't remit any of the proceeds to the UK) or will the vested RSUs be treated as UK earnings?
