Ridgley I think the way it works is that if you are convicted of a terrorist offence in this country you go to jail. Upon your release, you are deported. You are not, however, deported if your country of origin is likely to subject you to torture, or your life is genuinely at risk. This is true of all deportees, not just those convicted of terrorist offences. Gamu was staying here on a valid visa that has since expired. Since the request to extend the visa was turned down, she has to leave voluntarily or be deported. At the moment Zimbabwe is not automatically considered a jurisdiction that would torture or kill returning citizens so there is on the face of it no reason for her to be given a special dispensation to stay. All immigrants on time restricted visas are treated this way. So I think you aren't really comparing like with like, as it were. Terrorists don't get to stay for no reason, and people on expired visas don't get chucked out automatically. It turns on some quite strict rules about how likely the person is to be treated badly if they return, and how badly. It honestly isn't that easy a test to pass either - plenty of kurds were sent back to Iraq under the old regime when they were, in real life, highly likely to be treated badly, but the UK Border Agency thought otherwise. Not sure if that helps? {just seen that I cross posted with Mockney saying just about the same thing really}
