The countdown to the transformation of the immigration system began today when the Home Secretary announced new rules for highly skilled foreign workers applying to come to the UK. In a wide ranging speech at the London School of Economics, the Home Secretary Jacqui Smith announced changes to the UK's immigration regime to ensure the system is firm but fair and supports Britain's shared values. The proposals published today include: plans to ensure that migrants can integrate into communities through strengthened requirements for English language; plans to ensure all migrants play by the rules with strengthened restrictions on citizenship for those who break the law and protection for vulnerable people through measures to combat forced marriage. Jacqui Smith said: "Migration brings great social and economic benefits to this country. But people expect it to be managed robustly and in support of Britain's national interests. That’s why we’re launching the countdown to our new Points Based System which will begin in less than 100 days. "The Points Based System will build on a package of measures already being introduced to deliver a more secure border.  These include: new electronic checks to count people in and out of the UK and clamp down on illegal immigration; fingerprinting of visa applicants around the world before they are allowed to enter Britain; and the introduction of ID cards for foreign nationals. "I want people coming to live and work in the UK and their families to be able to integrate fully into our society.  So as well as our existing and planned requirements for English language proficiency, attached to settlement, citizenship and for skilled workers, I am today publishing proposals for new requirements for spouses who plan to settle here to have some knowledge of English prior to arrival. "I believe it is right that we protect those at risk and that is why I am proposing that the age at which a person can sponsor or be sponsored to come to the UK for marriage is raised from 18 to 21. "For those foreign nationals already living and working in the UK, I also believe that it is right that they play by the rules. That is why I want to strengthen our ability to block the privilege of citizenship to those with a criminal record. After all British citizenship is a privilege, not a right." The Government's Australian-style Points Based System and the new independent Migration Advisory Committee, which will meet for the first time on 7 December, will provide new, robust machinery to ensure  that only those who meet the needs of the UK will be allowed to enter and work.  The statement of intent for Tier 1 shows how the new tier will replace eight existing immigration routes for people who are highly skilled, entrepreneurs, investors or have undertaken studies to a high level and want to stay in the UK to work. Applicants will earn points for their skills and the potential they show for economic success, competence in English language and ability to support themselves and their dependents.  New measures to help to protect the vulnerable from being pressurised into forced marriage were proposed by the Home Office in a consultation published today. Proposals include raising the minimum age at which people can come to this country for marriage from 18 to 21. A separate consultation, also published today seeks views on the introduction of an English language test before entry for people applying for a spouse visa to help to encourage successful integration. A reform of the system was also announced to make it even harder for foreigners with criminal convictions to ever become British. Under new guidance, which will apply from 1 January 2008, it will be made absolutely clear that people with an unspent conviction will normally be refused nationality.
