英国签证学生几年？
2018年4月更新的政策如下 - The new student route is open to students who want to study at university in the UK. It is for applicants from outside the European Economic Area (EEA) and Switzerland， as well as those already living illegally or working in this country， even if they have a valid visa. The only exception are Irish nationals. These people will need to apply online for a student visa which costs £319 and requires proof of identity， proof of funding， English language proficiency and a criminal record check. They must also pay an immigration health surcharge of £450 per year while studying in the UK.
The government says these changes are necessary because existing routes were 'open to abuse' by those with no intention to study but were able to get work permits. There has been criticism that the fees could deter genuine students. In July 2017 it was reported more than two dozen universities and colleges had stopped advertising courses on the government’s own website after complaints about the high cost. But Universities UK said it welcomed the move， adding the fees are justified given the cost of checking applications.
In May last year， Theresa May announced similar measures would be introduced before the end of her first term in power， giving universities until April 2018 to prepare. This means those applying now can expect their visas to expire six months after completing studies – up to a maximum of five years. Currently， migrants seeking long-term study visas can stay in the UK indefinitely once they complete any course lasting longer than nine months. However， they may have difficulties obtaining permanent residence due to the ‘overstay’ period. Under the new rules， there will be a separate route for postgraduate researchers called the post-study work visa， which allows them to stay in the UK for three years rather than four. Those eligible include PhD graduates， and masters’ degree holders in computer science， engineering etc where they undertake a research project related to their degree. They still require a student visa. Both the Home Office and Universities UK say this will help attract higher quality overseas scholars into Britain.
This change applies to future students starting courses from autumn 2016 onwards. For
