I am sorry but there IS uncontrolled Immigration into the UK despite your assertion.
It happens in this way.
A person enters on a visitors Visa and overstays.
They work illegally, almost certainly seek to marry a UK Citizen and then they apply for, and are given permission to stay. You can contact serviceds offering arranged marriages in practically all UK Cities and big towns.
They do not marry but remain at large, and when caught apply for leave to stay because they have become "settled".
Labour have reduced our Immigration Service to little more than a few people working at an incredible rate but still only leaving little more than a scratch on the surface.
Just watch the Fly on the Wall TV series which follows the Borders and Immigration Agency and see how people routinely ignore the system and are then allowed to stay. Only the most flagrant of cases of abuse ever seem to be put forward for Deportation, and then as we know, the likes of Cherie Bliar are waiting to fight your corner no matter how "guilty" you are of failing to comply with the system.
Contrast this with a certain Foreign Country (EU) where I was recently.
If you get married, you do NOT get any "Right" to stay, neither can you claim Citizenship on the back of your marriage partner for (as I recall) 7 years. Medical care only applies to EU Passport holders. No Benefits, no free housing.
Yet another Country.......You are required to apply for an extension to your 30 day Visitors Visa within that period. It will be granted ONLY if you can prove that you have a valid reason and can support yourself. You are not entitled to any form of free medical care, you are required to insure yourself and pay for your treatment. Contrast this with the UK where it is a known fact that we suffer from "medical tourism".
Same Country.....You cannot buy anything beyond food, drink, hotels, etc without a tax card. This card proves that you are a citizen of the Country or you have leave to remain. Without the card you cannot rent property, buy anything on credit, obtain a credit card or even purchase a PAYG mobile phone.
If you are given leave to stay (EXCEPTIONAL) circumstances only, you are required to make your own medical provision and are not entitled to any form of Government support, i.e. no benefits, healthcare, etc, etc. You are also required to provide guarantors and live only at the address you have notified.
Leave to stay is not given to anyone with a prison record, and you are required to provide documentary evidence of this.
All applications HAVE to be done in the UK or other Country BEFORE departure. If you later opt to stay then its back home for you and re-apply to re-enter.
If you go missing at the end of your stay you WILL be found and imprisoned, no questions, and deported when you have served your sentence.
This is a Country proud of its Human Rights but more importantly it is fiercely protective of its borders and the people it lets in.
THAT is Controlled Immigration
By the way here is the link to the London Evening Standard article.
