Question to the Home Office:

To ask the Secretary of State for the Home Department, how many Home Office enforcement visits were undertaken without notice to (a) employers, (b) colleges and (c) universities in each of the last five years.

We are unable to provide the data requested via Home Office Published Statistics or Management Information as this information is not held in a reportable format. We do hold data on the number of enforcement visits,
however our systems do not easily distinguish between those where the visit was unannounced and those where the employer / college was notified in advance.
