Hi

Hi I'm here to find out how my Filipino gf can come and work as a caregiver in London

If your gf is a nurse, she can check NHS website and try to apply. If not, she has to have a spouse visa.

Thanks she's not a nurse unfortunately

That's the problem. It's hard to get an employer who will sponsor you. Employers want people who are ready to work without the need of visa.

Marriage is the only way really.
