They acknowledged that I was no longer expected to be financially responsible for her upkeep and welfare. They also said that they were not going to revoke the visa and that she free to stay for the duration of it.
Thanks for kind words of encouragement.. I've spent long enough grieving for what was lost and it's time now to look at future with new eyes and mended heart
I'm glad to see you have sorted this. Trying to go for your money too was just too much.
If there isn't much time left on a visa, then UKVI just let that run out to give them time to pack up and leave. Or they can use that limited time to try to to stay by putting in a valid, in time, application for another visa, if they are allowed to switch (in country) to that visa.
If they overstay now, then they get hit by the two new immigration laws: DVLA revoke their driving licence, UKVI advise the NHS that they must now be billed, bank accounts are closed, landlords are not allowed to house them even if it is a room rented in their own house, it's a criminal offence to work etc
