Those that go through the initial application without interview will probably have the pleasure of a Home Office visit or interview at either visa extension or ILR. Even then there are a few cases that don’t or have never been interviewed or visited because they have plainly met and beyond all the criteria at all points.
If established business owners choose to expand into the UK, have the financial backing and knowledge then those were the very individuals that the UK was trying to attract.
The issue as always was the use of this application route by many that were at best speculative business individuals, their funds were dubious, they had no business experience and essentially it was a punt to get into the UK. That is why there are so many bad news stories on this forum and why the route in this form has been closed.
