I wouldn't be so quick to dismiss it, Susan.
There are visas people can apply for to stay in the UK. It's just a matter of figuring out if there is one. There are student visas and work visas. They might not all apply in the OPs case, but you don't have to be British or Irish (or EU) to live in the UK.
Normally no, but the lady said on her other thread that she is 72 years old. Which is why I mentioned Irish and UK citizenship as that would allow her to live permanently in the UK and have NHS for free without working. There is an agreement between the UK and Ireland only, that when we arrive in each others countries, we are treated as "settled"/PR.
From what Nancy put in her opening posts, I ruled all the visas out.
A student visa doesn't allow people to settle permanently in the UK. Nancy would need to study and then find a business to sponsor her on a Tier 2 (General) unrestricted visa and keep on that visa for 5 years to ILR.
The new rules of student progression and student cap, together with the removal of Tier 1 (PSW), have stopped students hanging around without a Tier2(General) and using the '10 years legally in the UK' route to settlement.
For the work visas, there is:-
Tier 2 (General) Restricted visas. Very hard to get (from outside the UK) unless she does an in demand job or can earn over £152,000(ish) in the UK.
and
Tier2 (ICT) but she would have to have worked for that company for a year before she came to the UK and it doesn't lead to settlement anymore. These visa holders are not allowed to change to Tier 2 General until they have had a 1 year cooling off period outside the UK: and then they have to apply for the difficult to get, restricted visa (above).
The only other ones seem to be the two new Tier 1 visas - Entrepreneur, which seems to need 200k and a business that has to employ staff - Investor, that seems to need one million(?) pounds.
