Student Visitor Visa
Student Visitor visas are for students wishing to combine a visit to the UK lasting less than six months with a short course of study.
Any course at any level can be studied on this visa. Students wishing to study English in particular can apply through this visa to study for 11 months.
Student Visitors are not allowed to work part time at all.
Tier 4 (General) Visa
Tier 4 (General) is the visa category for students over 16 who want to complete a Further Education level course in the UK.
To qualify for a Tier 4 (General) visa you must study a course at Level 3 or above. International students can complete two years of FE-level study on a Tier 4 (General) visa, before being required to progress to Higher Education.
Under the conditions of this visa, international students are not allowed to work at all.
UKBA is repeated again a lot through the text so needs replacing as above.
To apply for a Tier 4 (General) visa you will need to provide an English language certificate (eg IELTS) to the UKBA.
