The UK Home Office lacks basic information on whether migrants leave the country when their skilled-worker visas expire, a report by Parliament’s Public Accounts Committee said on Friday. The cross-party panel found that the department has not analysed exit-check data since the visa route was launched in December 2020 and still relies on matching internal records with airline passenger lists to gauge departures. Since its introduction, the skilled-worker scheme has received about 1.18 million applications, including 630,000 dependants, yet officials cannot say how many of these people have overstayed or are working illegally. Committee chair Sir Geoffrey Clifton-Brown said the absence of such “basic information” undermines the integrity of the immigration system and hampers efforts to protect workers from abuse. The committee also highlighted the risk of exploitation following the route’s 2022 expansion to ease labour shortages in adult social care. The Home Office has revoked more than 470 sponsor licences in that sector between July 2022 and December 2024, affecting over 39,000 workers, but concedes it cannot quantify how many victims of modern slavery or other abuses remain. MPs urged the department to set out how it will record migrant departures and work with other agencies to monitor exploitation. A Home Office spokesperson said the government is “fixing a broken system,” citing tougher sponsorship rules, higher skill thresholds and an end to overseas recruitment for care-worker roles as part of wider plans to cut net migration and restore public trust.
