Question to the Home Office:

To ask the Secretary of State for the Home Department, how many people were not recorded as having left the UK before the expiry of their visa in the year ending March 2025.

Data on the number of visa holders who have or have not departed the country following the end of their granted leave, as derived from the Home Office’s Initial Status Analysis (ISA) system, was previously published in the “Reports on statistics relating to exit checks” statistical series.

This publication was paused following the August 2020 publication due to data quality concerns arising from COVID-19, changes to the UK’s immigration system, and underlying developments to the system which underpins the data used in this publication. These developments were previously detailed in the Developments in Exit Checks report, published February 2022.

Since then, significant progress has been made in addressing data quality concerns and the robustness of these statistics. While work is ongoing, we anticipate a resumption of publication of these statistics later this year.
