Lol, that's for legal migrants
You can apply online for a change to your conditions if your financial circumstances change and you:
- have permission to stay on the basis of your family or private life
- have applied for permission to stay on the basis of your family or private life
- have permission to stay with a close relative with protection status as a child
- hold a British National (Overseas) visa
- have permission granted on any other immigration route and you want to apply on a discretionary basis because your circumstances are particularly compelling
Note the permission thing.
Leveraged buyout is insane and should be so very very illegal.
