the rules are
To settle in the UK as a skilled worker, non-EU migrants need to have a Tier 2 visa. For this you need:
An offer for a job in the UK that pays at least £20,800
Have had at least £945 in your bank account for 90 days
A certificate of sponsorship from your employer (which can cost between £536 and £1,476)
To pay a £200 annual healthcare surcharge
To prove your English language proficiency
After five years on this visa, skilled workers are able to apply for ‘indefinite leave to remain’ – and this is what is about to change.
From April, anyone applying for indefinite leave to remain will need to earn at least £35,000.
you just have to prove you can support yourself long term here . £35,000 is not alot here , any less than that and you will really struggle to cover rent and other bills.
its important to note . it does not mean you would be deported it simply means you wouldnt be allowed a visa to remain forever you would have to carry on applying for a temporary one everytime it runs out .
