政府应该提高或者减少对于高级技术移民临时工作签证的发放？

英国应增加或减少所用的临时工作签证给高技能移民工人吗?

Between 2008 and 2010 the United Kingdom began implementing a five tiered “points-based immigration system” which separated immigrant applicants into five tiers based on their employment potential. To secure a skilled worker visa, people have to qualify for 70 points. Having a job offer from an approved employer for a skilled job and being able to speak English will give 50 points. The applicant can achieve the remaining 20 points if they are due to be paid at least £25,600 a year. They can also gain extra points for having better qualifications (10 points for a relevant…   PhD, or 20 points for a PhD in science, technology, engineering or maths) or an offer of a job in which the UK has a shortage (20 points), even if it doesn’t pay as much money. Certain jobs in health or education still merit 20 points even if the salary is less than £25,600. The applicant must be paid at least £20,480, and in line with set amounts for particular jobs in the UK’s four nations. The exception to this is Irish citizens, who are still able to live and work in the UK as part of the Common Travel Area.
