Question to the Home Office:

To ask Her Majesty's Government how many students have had their visas revoked or curtailed for allegedly cheating in Government-approved English proficiency tests in each year since 2014; how many were detained or forcibly removed in that period; how many students made challenges to decisions; and how many cases are awaiting decision by the Court of Appeal.

The exact information requested is not held centrally by the Home Office. UKVI transparency data provides details of refusal, curtailments and removal decisions on those linked to the abuse of secure English language testing. A link to the most recent available data is provided here;
https://www.gov.uk/government/publications/temporary-and-permanent-migration-data-february-2017

The table in SELT_02 is the closest match to the information requested.

The data was last published in February 2017 and only contains data to the last quarter (December 2016). ETS data is no longer published after this date.
