Question to the Home Office:

To ask the Secretary of State for the Home Department, how much was accrued to the public purse from charging international students applying for Tier 4 student visas in each year since 2010.

Visa income is not differentiated between the various categories in which they are received.

Visa volumes by broad category (study, work etc) are published in the data section of this webpage: https://www.gov.uk/government/publications/immigration-statistics-january-to-march-2017/why-do-people-come-to-the-uk-3-to-study#data-tables

Fees and unit costs are also published, for example, for 2017/18:
