I've been in the UK since May, but I've been subletting apartments. I have a permanent job and I'm able to save 70% of my salary.
I have the bank account in Lloyds and they told me that I'm not eligible for a credit card (almost all my salary, I invest, so theoretically they see it as spendings).
I need a credit card mostly because I want to rent a car and optionally would be nice to have chargeback and some good cashback offers.
How can I get a credit card without a permanent address, taking into consideration my investments (most of the investments are ETFs)?
