I'm sure one of the legal eagles here will advise you but I really don't think this woman has to worry about being sent home.
Is her FLR still current or have the extensions run out now?
Also...........thinking here, when did the new regulations for ILR start guys? Did she actually need extensions? Surely someone entering 5 years ago was under the old rules and would have been given ILR after 2 years as a matter of course providing she was still with her husband?
Whether she is or is not eligible for accommodation, the 2 kids born to a UK father certainly are. I think she should see a solicitor ASAP - that cannot be a healthy environment for kids to live in. Has the husband said that he wants the kids to stay with him?
