I want to apply here in saudi for settlement visa i need to know if i have a chance of approval if i apply here since i have the work and my income is good. Can i apply and work also here if i will be approve?
No, If you are applying for settlement visa then you will need to be in the UK after the visa is issued. Having the job in Saudi will have no bearing on the visa application as you would be expected to leave your job to settle in the UK.
